world_countries 3.9.4

world_countries: ^3.9.4 copied to clipboard

NEW FEATURES

• This version introduces named (Dart 3.10 dot-shorthand compatible) constructors for ISO classes, refactoring the ISO data files to use a factory constructor pattern with extension types. The changes transform the direct constructor calls into a more structured factory-based approach while maintaining backward compatibility. For example, instead of using CountrySvk(), you can now use WorldCountry.svk(). This change enhances code readability and aligns with modern Dart practices.

const country = CountrySvk(); // Old way (still supported).
const country = WorldCountry.svk(); // New way, or just .svk() in Dart 3.10.

print([WorldCountry.svk(), WorldCountry.cze()]); // Collections, 3.9 way.
// You can also use the new dot-shorthand syntax introduced in Dart 3.10:
print(<WorldCountry>[.svk(), .cze()]); // Collections, 3.10 way.

CHORE

• Bulgarian currencies array updated to reflect current usage of both BGN and EUR in Bulgaria.

DOCUMENTATION

• Added benchmarks & regression verification documentation.

• Deprecates ANG, BGN, and ZWL currencies with appropriate migration paths.

FIX

• Corrected Slovak country name for CIV to "Pobrežie Slonoviny".
• Corrected English currency name for KGS to "Kyrgyzstani Som".
• Corrected English currency name for GYD to "Guyanese Dollar".

REFACTOR

CHORE

• Enable and fix 10 new Dart Code Metrics rules (from the 1.32.0: October Update).

DOCUMENTATION

• Improved documentation in README.

NEW FEATURES

• MaybeWidget gains a new optional buildWhen predicate parameter (all constructors) allowing additional conditional logic beyond simple null checks. When provided and returns false, the widget (or list / nullable result) is skipped and the fallback (orElse / empty list / null) is used.
• New static factory MaybeWidget.orNull - builds and returns a widget only when the provided value is non-null (and an optional buildWhen predicate, if supplied, returns true); otherwise it returns null (instead of inserting an empty placeholder). This is ideal for concise conditional inclusion in collection literals or nullable child parameters.
• Improve Norfolk Island (NF) flag.
• Added isZero getter on num? (in helpers library).
• Added nullable maybeScaffold and maybeMessenger getters (in extensions on BuildContext, helpers library).

REFACTOR

• Adjust title alignment in default searchSuggestions builder (with new ListTile parameters, provided in Flutter SDK v3.35.4).
• Multiple improvements in metadata - including @useResult (and other) annotations and updated interfaces.
• Added assert statements to copyWith methods for validation.
• Updated flag properties from isSimplified: true to isSimplified: null across multiple countries.

DOCUMENTATION

• Improve example/demo web. Revamped Settings page with Material 3, sliver app bar, toolbar with reset, and a scaled flag preview. Added new controls for aspect ratio, border (radius, width, color) and shadow (spread, blur, opacity, offsets).
• Added demo website to homepage in pubspec.yaml.
• Enhanced documentation for flag's isSimplified property with detailed explanations.

NEW FEATURES

• List tiles support Material state controllers.
• Text fields gain select-all-on-focus and locale-specific hint options.
• Added Guernsey flag painter (GgyPainter) and export, so GGY is no longer a "simplified" flag.

REFACTOR

• Deprecated static method TypedLocaleDelegate.maybeOf(context) in favor of TypedLocaleDelegate.of(context).
• Made Shape implementations final; added deprecations for legacy helpers (to be replaced with modern switch expressions).
• Selectively disable anti-aliasing for axis-aligned rectangles (e.g., BLR vertical line, SAU sabre) to avoid blur; keep AA for diagonals.

FIX

• Corrected the dense CountryTile title alignment so it centers with the flag.
• Oman flag default aspect ratio corrected (from 2 to 7/4).
• Fixed white rectangle position in Belarusian flag (on smaller sizes).
• CountryName's short flag (true) in toString() override returns common name, same way, as in parent's (TranslatedName class) override.

CHORE

• The Dart SDK was bumped to v3.9.2.

DOCUMENTATION

• Improved example app and demo website (with Settings menu).

FIX

• Updated country data with recent population, Gini, and capital information.
• Fixed demonyms, borders, and native names for select countries.
• Corrected Welsh official country name for Curaçao.
• Corrected Korean localization for British Indian Ocean Territory, Dominica, Mongolia, Wallis and Futuna and South Georgia.
• Corrected subunitToUnit value for Hungarian Forint.

NEW FEATURES

• Added platform dispatcher extension for convenient access to country, language, and script information from platform locales.
• Flag anti-aliasing is now smarter - it's defined on element painters level, so rectangle elements are no longer anti-aliased.
• Added copyWith extension for IsoFlag, also exposed flag data maps map and alternativeMap via public getters for easier access.
• Added a new property FlagElementsType? baseElementType to flag data FlagProperties indicating the base geometric or symbolic element of each flag, enhancing metadata and classification.
• Also added an isSimplified property to flag definitions, allowing users to distinguish between simplified and fully detailed flags.
• Updated language metadata to better reflect writing systems and script directionality for many languages.

REFACTOR

• Deprecated ineffective anti-aliasing override flagAntiAliasOverride properties and improved anti-aliasing handling in flag rendering.
• Optimized flag painting performance for stripes and stars, reducing redundant object creation and improving rendering efficiency.
• Deprecated fullFlags list in favor of new isSimplified property.
• Marked certain currencies as deprecated and updated related comments.
• Standardized code normalization using new ISO code extension types, replacing older string and object extension methods.
• Deprecated legacy constant lists in favor of centralized static lists for ISO classes.
• Corrected country and language associations in documentation for currencies and languages.
• Deprecated functional-style pattern matching methods and boolean type-check getters across ISO/sealed models. Users are advised to use switch expressions or direct equality/type checks instead.
• Deprecated extensions providing is* getters in favor of direct type checks.
• Standardized method return types for map serialization to use stronger, standard Dart Map types.
• Simplified code by removing redundant comments and improving null-aware syntax usage.

• Added or updated test cases to cover new behaviors and deprecation handling.

FIX

• Adjust height and width factors for Afghanistan flag properties and update ShahadaPainter translation logic.

NEW FEATURES

• Introduced adaptive flag selection for language and currency pickers (via .adaptiveFlag constructor), automatically displaying the most relevant flag based on locale or user context. For example - they automatically show the most relevant flag based on the user's device locale, like showing the Austrian flag 🇦🇹 for the German language if the user is in Austria.
• All pickers now support customizable flag maps and adaptive flag logic for enhanced visual customization (via flagsMap parameter).
• ClearButton now extends IconButton so it supports all its super parameters, plus several params from the AnimatedCrossFade widget.
• Added new flag definitions for international and constructed languages (e.g., European Union, Esperanto, Ido, Interlingue, Interlingua, Volapük).
• Introduce IsoFlag widget and DecoratedFlagWidget base class.
• Unified flag widget interfaces to support foreground child widgets, explicit sizing, and improved decoration options.
• Added height and width parameters to the BasicFlag.

• Introduced methods to prioritize and customize country associations for languages and currencies.
• Improved diagnostics and theming for flag widgets, including support for custom overlay widgets.
• Added new extension methods and interfaces for easier flag and country data access.

CHORE

• The Dart SDK was bumped to v3.8.1.
• The meta package has been added as an explicit dependency, but it has the same version constraints as the current stable Flutter SDK version (3.32.4).

TEST

• Add tests for comparable boolean getters in ISO standardized classes.
• Add unit tests for regional code and ISO standardized extensions.
• Add unit tests for ListItemTile extension functionality.

NEW FEATURES

• Added support for custom search result building in all pickers and searchable widgets via a new onSearchResultsBuilder parameter, enabling advanced search algorithms like fuzzy search.
• Introduced customizable localization formatting for ISO translations with a new L10N formatter callback. Kudos to @MaxLap.
• Added the regionalCode getter to the BasicTypedLocale to provide a convenient alias for the countryCode property, improving consistency when working with regional locales.

DOCUMENTATION

• Update dartdoc documentation for countries to use backticks for ISO code formatting.
• Enhanced documentation with new FAQ sections and detailed examples on customizing search and localization.

REFACTOR

• Search performance has been significantly improved in pickers (that feature a search bar) and the search delegate, by implementing search map caching.
• Replaced text-based flag rendering with vector path drawing for Iraq, Afghanistan, Saudi Arabia and U.S. Virgin Islands flags, improving rendering consistency on all platforms.
• Deprecated flagTextStyleOverride getter and setter (visible for testing) as text-based painters were removed.

TESTS

• Updated goldens for Iraq, Afghanistan, Saudi Arabia and U.S. Virgin Islands flags.
• Expanded test coverage for custom search algorithms and localization formatting features.

This is a DevEx release without significant changes for the users, that aims to improve developer experience when working with flags in DevTools.

NEW FEATURES

• To enhance debugging, widgets like CountryFlag, BasicFlag, MaybeWidget, etc. now override debugFillProperties, providing detailed information, including values and rationales. Crucially, this allows you to visualize emoji flags directly in dev tools, replacing generic widget names.

CHORE

• Example app runners update.

DOCUMENTATION

• Highlight importance of TypedLocaleDelegate usage in app's localizationsDelegates, for pickers L10N and improved search functionality. Thanks @wildsurfer!

REFACTOR

• Enhanced translation fallback mechanism in pickers. Previously, translations would only use the first available locale. Now, the system tries multiple sources in sequence:
  1. Direct translation provided to the picker.
  2. Theme-level translation from PickersThemeData.
  3. Global app translation from localizationsDelegates via TypedLocaleDelegate.
• Added assertion messages to help developers identify missing translations more easily.
• Improved translation debugging through more descriptive error messages.

This is maintenance release without significant changes for the users, that aims to fix dropped pub score after Flutter v3.29.0.

CHORE

• Dart SDK bumped to v3.7.0.
• Code has been formatted with the new Dart formatter.
• Deprecated scribbleEnabled is replaced with stylusHandwritingEnabled parameter in AdaptiveSearchTextField.

NEW FEATURES

• Added two new offstage constructor and static list method, to MaybeWidget. MaybeWidget.offstage - Preserves layout space but hides the widget if the provided value is null. Ideal if you want to conditionally toggle visibility without removing the widget from the tree. MaybeWidget.list - Builds either a single widget or multiple widgets if value is not null, or returns an empty list if it is null. Gives you a flexible way to handle conditional UI blocks or spread-like usage in the Flex widgets.

REFACTOR

• Nullable maybeCommonNameFor method now accepts nullable mainLocale parameter - if null is provided, null will be returned.

🎉 Second anniversary and new major release!

NEW FEATURES

• Introduced new methods for working with common names and common name maps: commonNamesMap on ISO collections and commonNameFor/maybeCommonNameFor on ISO objects. These methods are significantly faster than the old translations - related methods because they work directly with locale-specific maps instead of iterating through all translations of each ISO object.
• The translations getter is now a computed field. This means it will only generate the translations when they are requested, rather than storing them all in memory. It's recommended to cache the results of the getter to avoid redundant calculations. Because of that - translation and maybeTranslation methods are no longer recommended for retrieving localization data.
• The commonNamesCacheMap is deprecated because it relies on the memory-intensive translations getter.
• New localization delegates on IsoTranslated objects simplify complex queries for object localizations.
• Bool getters on IsoStandardized objects can now be applied to null values. For example, maybeIso.isRus will return false if maybeIso is null, without the need for additional null-checks.

REFACTOR

• Improved generics handling in localization methods.
• Update and use stable L10N packages.

FIX

• Replaced deprecated Color methods .withOpacity with new .withAlpha
• Changed official name for Portugal: "República português" > "República Portuguesa".
• Change the capital of Indonesia for Nusantara: "Jakarta" > "Nusantara".

BREAKING CHANGES

• The package now requires Flutter v3.27.1 or higher.
• The IsoTranslated<T, N, L> class now uses three generic types instead of two. If you used this class directly in your code, simply add the additional generic <L extends BasicLocale> to your reference.
• BasicPicker, BaseTileThemeData and BaseTileThemeData are now inherited from IsoTranslated instead of Translated class.
• IsoLocale is now deprecated in favor of TypedLocale that now implements BasicTypedLocale instead of BasicLocale.
• Generic and base keyword on TypedLocale class are removed, you can still use new regionalCode parameter to provide non-typed region/country info there.
• The default toString() implementation of BasicLocale now uses Flutter's Locale-like output format. You can still access the old output by setting the short flag to false.
• The sealed_country_translations library is removed. Migrate to the l10n_countries package or use l10n getter in ISO objects that provides the same data without holding all translations in memory. This sub-library and its content (except for supported locales lists - they will be moved to the main library) will be removed in the next major package version.
• From now on, you will most likely need to explicitly provide a localizationsDelegates: const [TypedLocaleDelegate()], to your app, for pickers L10N and improved search.
• Country translation methods requires BasicTypedLocale instead of BasicLocale, if you didn't used country value - this change will not affect you, same applies to TypedLocale. If you provided non-typed country data there - please change from:

BasicLocale(*, countryCode: "US");
// or
TypedLocale(*, country: "US");

to:

BasicTypedLocale(*, regionalCode: "US"); // or BasicTypedLocale(*, country: CountryUsa());
// or
TypedLocale(*, regionalCode: "US"); // or TypedLocale(*, country: CountryUsa());

NEW FEATURES

• Added new method for the FunctionalPlatform - maybeWhen (in addition to hash-map like method maybeWhenConst that works with mostly immutable object returns (instead of closures in the new method)).
• Improved showInSearch method pop handling.
• A searchSuggestions method might be affected by the SDK bug fixed in v3.27.0. As a temporary workaround, you can create your own instance of SearchController and dispose of it manually.
• Updated the postal code pattern format for Paraguay.
• Updated International Olympic Committee (IOC) country code for Bahrain.
• Improvements of toString() method implementations in models and addressing new lints + DCM reports.
• Added "polski" to the Polish language's namesNative array.

NEW FEATURES

• Added FlagExtension on WorldCountry to provide flag-related properties and colors:
  • flagStripeColors: Retrieves the stripe colors of the flag from FlagProperties.
  • flagElementsColors: Retrieves the element colors of the flag from FlagProperties.
  • flagColors: Combines flagStripeColors and flagElementsColors into a single list of colors.
  • flagProperties: Retrieves the FlagProperties associated with country (from the default WorldCountry.list).

BREAKING CHANGES

• Package requires Flutter version 3.19+, because it now uses Semantics identifier property in all picker's tiles (this property was introduced in that SDK version). This identifier describes the node for UI automation tools that work by querying the accessibility hierarchy, such as Android UI Automator, iOS XCUITest, or Appium. It's not exposed to users.
• All previously deprecated code, marked with the @Deprecated annotation, has been removed. Including color font emojis (you can still use them on your own via EmojiFlag.custom constructor, example code is provided in the example project).

NEW FEATURES

• All pickers are updated with accessibility in mind, ensuring seamless integration with screen readers and assistive technologies. Feel free to use SemanticsDebugger to check it.
• CountryFlag now offers alternativeMap parameter that you can use to provide alternative look of the country flag. By default it contains updated Afghanistan flag (with official design from year 2021) and alternative French Guiana flags.
• CountryFlag now have non-required child property.

REFACTOR

• New asserts in the constructors and optimizations in several country flag painters.

TESTS

• Added tests for new flag asserts and update goldens with arabic fonts.

NEW FEATURES

The package now uses CountryFlag from the world_flags package to display flags in the default country and phone code pickers. This approach offers several benefits:

• More customization: CountryFlag provides greater flexibility for customizing the appearance of flags.
• Improved performance: These flags offer better performance compared to the assets.
• Platform independence: They work seamlessly across different platforms.
• No assets required: Since they are drawn using Flutter's CustomPainter, they don't require additional platform dependant and heavy font assets.

Asset based EmojiFlags are being deprecated, but you can still use them until the next major update, you will be also able to use them after v2.0.0 with EmojiFlag.custom if needed.

MaterialApp(
  ...
  theme: ThemeData(
    extensions: const <ThemeExtension>[
      /// The `emojiFamily` will work until v2.0.0, with old, assets based flags.
      CountryTileThemeData(emojiFamily: EmojiFamily.twemoji),
      /// Instead you can migrate to FlagThemeData, where you can specify way more properties.
      FlagThemeData(
        decoration: BoxDecoration(borderRadius: BorderRadius.all(Radius.circular(4))),
      ),
    ],
  )
);

NEW FEATURES

• 🎉 All translations in the eco-system packages now support all GlobalMaterialLocalizations and GlobalCupertinoLocalizations locales.
• 🦾 Countries translations now also support all GlobalMaterialLocalization + GlobalCupertinoLocalizations locales.
• The locale parameter in the maybeTranslation method is now nullable.
• The permissive constructors are now even more permissive, only name and code parameters remain required.
• Changed Vatican city unMember field to false and fix Cape Verde coordinates Link to MR
• Added new DurationExtension to the helpers library.
• Added new TypedLocaleExtension with a copyWithTranslationsCache(Async) method.
• Added asyncTranslationCacheProcessing parameter for the TypedLocaleDelegate.
• Added withTranslationsCache constructor for TypedLocale and IsoLocale.
• Set default value for startWithSearch in the country and phone code pickers also to false, to unify behavior across the pickers.

NEW FEATURES

• 🦾 Language translations now also support all GlobalMaterialLocalization + GlobalCupertinoLocalizations locales.
• You can now provide translation caches list in TypedLocaleDelegate and it's new selectiveCache constructor. This is useful when you don't want to cache the translations for the specific unused ISO objects. For example you are only using country pickers, so you might not need currency an language translations. In this case you can provide only countriesForTranslationCache for the countries translation cache.
• The TypedLocale (so and IsoLocale) has new fields for storing translations cache (see the point above).
• The TypedLocale (so and IsoLocale) are now inherited from BasicLocale (so and JsonEncodable), so they can be used in the translations directly.
• Added copyWith method in in TypedLocale (so and IsoLocale).
• Added new internationalName getter in IsoStandardized interface, representing the international name of the ISO object.
• Added new UpperCaseMap class, that UpperCaseIsoMap extends, a simple version of UpperCaseIsoMap without key length checks and IsoStandardized values requirement.
• The map in the RegionalBloc is now UpperCaseMap (with all it's benefits).
• Added new maybeFromAcronym factory method in the RegionalBloc.
• Added new BasicLocale class, that TranslatedName extends. Representing a type-safe world locale (language, country/region code and script).
• Deprecated maybeTranslate and translate methods for translated classes (use maybeTranslation and translation instead).
• Added new commonNamesCacheMap method for all ISO based sealed classes collections, which allows to create a cache map of common names translations for the given BasicLocale.

BREAKING CHANGES

Because of the BasicLocale changes (described above), translation() and maybeTranslation() methods on the Translated classes now require BasicLocale input. If you are not using those methods directly, then you don't need to change anything, otherwise you will need to do small adjustment - wrap the content of those methods with a BasicLocale.

Before:

print(iso?.maybeTranslation(LangPor()));

After:

print(iso?.maybeTranslation(BasicLocale(LangPor())));

Or just:

1. Enable Regular Expressions in your IDE's Find and Replace panel.
2. In the Find field, enter the regex: (translation\()(.*)(\))
3. In the Replace field, enter: $1BasicLocale($2)$3
4. Execute the replace operation.

NEW FEATURES

• Use of UX/UI interpretation of Hick's Law for conditionally showing search bar in the SearchableIndexedListViewBuilder - If no showSearchBar value specified, it uses PickersThemeData.showHeader value as before but instead of falling back to default hardcoded false value it fallbacks to items count condition if (items.length > 5).
• PickersThemeData.showHeader is now nullable.
• Fix thousands separator for CHF.
• codeOther is no longer nullable (in all IsoStandardized classes).
• Added new compile-time constant and case-insensitive code maps (UpperCaseIsoMaps) in every ISO class (accessible as static constants via .map, .codeMap, .codeNumericMap, etc.).
• Factory constructors and methods now using those maps if no (optional) array is provided there.
• Factory constructors and methods in IsoStandardized classes now allow non-String inputs - any Object, for example you can now use StringBuffer or Enum instances directly:

 enum IsoEnum {de, fr, ar} // On .fromCode(IsoEnum.de) call it will use "DE" input.

or you can basically use any custom class with toString() override:

class CustomIsoCodeClass {
 const CustomIsoCodeClass({String code = '123', this.foo}) : _code = code;
 final String _code;
 final Foo? foo;

 @override
 String toString() => _code; // Has to override toString() with ISO value.
}

// On .fromAnyCode(CustomIsoCodeClass(code: ' 321 ')) call it will use "321" input.

REFACTOR

• Refactored asserts in maybeMapIsoCode method.
• Fixed typos in CHANGELOG and README.

NEW FEATURES

• Added new static maybeFrom* methods and refactored old ones. They are also now accept any Object? input instead of just String?.
• Added new and refactored old tests with a performance in mind.
• Added new firstIsoWhere* extensions on ISO iterables.
• Improved annotations.
• Added is* boolean getters for all ISO objects, for example:

if (isoObject.isFra) return _onFrench();

is more readable and shorter equivalent of this check:

if (isoObject == const LangFra()) return _onFrench();

NEW FEATURES

• Added new constructor called permissive - which allow the creation of custom class instances that are not fully compatible with the ISO standard.

• Translated class is now sealed - which means you can now directly compare instances of different ISO classes directly (for example in switch statements).

• Added theme extensions that you can specify in your ThemeData to provide global theme to your pickers. You can find PickersThemeData, CountryTileThemeData, CurrencyTileThemeData and LanguageTileThemeData:

MaterialApp(
  ...
  theme: ThemeData(
    /// And also [CurrencyTileThemeData], [LanguageTileThemeData], [CountryTileThemeData]...
    extensions: const <ThemeExtension>[
      PickersThemeData(primary: true), // Specify global pickers theme.
    ],
  )
);

This way you can specify for example that all your pickers lists are primary and define globally use of Twemoji as main flags font emoji family in all Country/Phone pickers in the app.

🎉 First anniversary and first stable release!

NEW FEATURES

• Added new getter for TranslatedName name called common, which might be useful in some cases when name is being used by a parent class.

• Added a lot of translations from the Symfony.

• Currencies translations now support all GlobalMaterialLocalizations and GlobalCupertinoLocalizations locales.

• Updated LICENSE.

• Added CLI tool for removing unused emoji font families on the Web platform dart run world_countries:clean_build [--keep twemoji,notoemoji,openmoji]

• Added fromSubtags constructors for IsoLocale and TypedLocale classes.

• Added defaultLocaleMapResolution for a TypedLocaleDelegate that maps:

  • fil Filipino (Pilipino) to tl Tagalog.
  • gsw Swiss German Alemannic Alsatian to de_CH German (Switzerland).
  • bs_Cyrl Bosnian (written in the Cyrillic script) to sr Serbian.

BREAKING CHANGES

• Removed code marked as Deprecated in previous releases.
• Replaced old FiatCurrency.list with a new FiatCurrency.listExtended.
• Removed FiatCurrency.regularList (please use FiatCurrency.list instead).
• Marked Croatian Kuna as Deprecated (currencies).
• Moved helpers of world_country package to separate library: BuildContextExtension, FunctionalPlatform, NameTextInput, ClearButton and UiConstants. To migrate just use IDE suggestions or manually replace old references:

import "package:world_countries/world_countries.dart";

to a new one:

import "package:world_countries/helpers.dart";

NEW FEATURES

• Added new interface IsoTranslated which combines Translated and IsoStandardizedinterfaces.
• Added standard* static constants in the WorldCountry class referencing different names of the ISO 3166-1 standard.
• Added standard* static constants in the FiatCurrency class referencing different names of the ISO 4217 standard.
• Improved documentation in README, added FAQ and demo web-site (Flutter WASM).

REFACTORING

• Removed NavigatorContextExtension from exports, so you don't need to specify it no longer via hide.

NEW FEATURES

• Added new factories to ISO classes - fromAnyCode, which do the length and type checks and redirects to other fromCode\* constructors
• Added new static methods to ISO classes - maybeFromAnyCode, which works same way as fromAnyCode, but doesn't throws StateErrors if no currency object is found.
• Added maybeMapIsoCode method to String extensions, which is used under the hood of (maybe)fromAnyCode.
• Added the TypedLocaleDelegate class, which can be used in the localizationsDelegates (such as in MaterialApp). It attempts to convert the string-based Locale to a strongly typed TypedLocale, which is then used in all pickers to provide translations for country/currency/language names. The detected TypedLocale? is also accessible via TypedLocaleDelegate.maybeOf(context) or simply context.maybeLocale.
• All pickers can have a local translation override via the translation parameter (which will be used instead of the TypedLocale translation).
• Translated classes now also have translate() and maybeTranslate() methods to translate it's data (country/currency/language names).

REFACTOR

• Slightly changed UI of default picker's tiles - added padding on top of the leading widget and swapped title with subtitle (because of translations provided to title).
• Named classes now has boolean flag (short, defaults to true).
• TranslatedName class by default returns .name value on toString().
• Refactored dollar symbols in toString() methods.

BREAKING CHANGE

• Country and phone code pickers now using TypedLocale as translation parameter (to migrate just wrap your previous language there with IsoLocale()).

This is a general update that synchronizes underlying Dart package updates (related to translations and interfaces), as a preparation for a bigger upcoming update for localization delegates.

NEW FEATURES

• WorldCountry class now contains way more translations of language name to other languages (79 translations for each language minimum).
• Refactored factory constructors - there is an optional parameter to provide custom list.
• Added regularList getter for the list of regular currencies (excludes 10 currencies from the specialPurposeList).
• FiatCurrency class now contains translations of language name to other languages (79 translations for each language minimum).
• Those translations are also accessible from the translation and maybeTranslation methods.
• Added TranslatedName class for the translations.
• Implement new abstract interfaces for currencies: Named and Translated.
• Added a new sealed class called Script, based on the ISO 15924 standard.
• The NaturalLanguage class now contains information about scripts (writing systems) and translations of the language name to other languages.

FIX

• Fixed several English currency names.

NEW FEATURES

• New searchSuggestions method in every picker (for use in suggestionsBuilder of SearchAnchor)
• Added search suggestions for search anchors.
• Added copyWith, toJson etc. to the WorldCountry, FiatCurrency, NaturalLanguage classes.
• Added copyWith, toJson etc. to all country-related sub-classes.
• Added new interfaces (IsoStandardized, JsonEncodable) and typedef (JsonMap) to the model.
• Refactoring in existing functional methods (sorting params to match list sorting).
• Translations are now List<TranslatedName> instead of List<CountryName>, however CountryName is just an extension on top of TranslatedName (you can reference to name instead of common and fullName instead of official). There will be way more translations provided in upcoming version 0.7.0.
• Renaming of extensions to follow the eco-system naming pattern.

REFACTOR

• Added new mixins.
• Improve example and docs.

• Factory constructors and static methods for data classes creation now implicitly trimming and comparing uppercase string inputs.
• Fixing old ignores and new linter rules.
• Updates in dev_dependencies.
• Added new data sealed classes related to world blocs.
