In this version, we have made extensive use of the intl package with a comprehensive set of new extensions to provide robust localization and formatting capabilities.

• Intl Extensions:
  • General:
    • Map: intlSelectLogic, intlSelect
    • Num: pluralize, getPluralCategory
    • String: setAsDefaultLocale, setAsSystemLocale, translate, genderSelect, getGenderCategory
  • DateFormat:
    • DateTime: tryFormat, format, and various formatting methods.
    • String: dateFormat, toDateFormatted, toDateFormattedLoose, toDateFormattedStrict, toDateFormattedUtc, localeExists.
  • Bidi Extensions:
    • TextDirection: toBidiFormatter
    • String: Various bidi text manipulation methods.
  • NumberFormat Extensions:
    • String: toNumFormatted, toIntFormatted, toDoubleFormatted.
    • Num: formatAsCurrency, formatAsCompact, and various other formatting methods.

Enhancements and Fixes #

• Enhanced number and date conversion functions (toNum, tryToNum, toInt, tryToInt, toDouble, tryToDouble, toDateTime, tryToDateTime) to include optional format and locale parameters.
• Fixed an issue in makeEncodable on Maps where sets were not properly converted to JSON-encodable lists.
• Consolidated several DateTime manipulation methods to ensure consistency and accuracy.
• Addressed various minor bugs and inconsistencies in existing extension methods.
• Enhanced documentation across several methods to improve clarity and usability.

Breaking Changes #

• toDateWithFormat replaced with toDateFormatted() on String.
• lastDayOfWeek and firstDayOfWeek are now methods with an optional startOfWeek parameter to customize the first day of the week (defaults to Monday). Improved time zone handling and added tests.

• New Feature: Added the toWords getter on String, which converts any String to a List<String>, handling complex cases more effectively than the native split() method.

  • Example Usage:

    print("FlutterAndDart_are-AWESOME".toWords); // [Flutter, And, Dart, are, AWESOME]
    

Enhancements

• String Case Conversions:
  • capitalizeFirstLetter: Now only capitalizes the first letter, preserving the rest of the case.
  • NEW: capitalizeFirstLowerRest: Provides the previous behavior, capitalizing the first letter and lowercasing the rest.

Added

• Expanded String Case Conversions: Added comprehensive case conversion extensions:

  • toPascalCase: PascalCase (UpperCamelCase).
  • toTitleCase: Title Case.
  • toCamelCase: camelCase (dromedaryCase).
  • toSnakeCase: snake_case (snail_case, pothole_case).
  • toKebabCase: kebab-case (dash-case, lisp-case, spinal-case).
  • toScreamingSnakeCase: SCREAMING_SNAKE_CASE (MACRO_CASE, CONSTANT_CASE, ALL_CAPS).
  • toScreamingKebabCase: SCREAMING-KEBAB-CASE (COBOL-CASE).
  • toPascalSnakeCase: Pascal_Snake_Case.
  • toPascalKebabCase: Pascal-Kebab-Case.
  • toTrainCase: Train-Case (HTTP-Header-Case).
  • toCamelSnakeCase: camel_Snake_Case.
  • toCamelKebabCase: camel-Kebab-Case.
  • toDotCase: dot.case.
  • toFlatCase: flatcase.
  • toScreamingCase: SCREAMINGCASE (UPPERCASE).

• Nullable String Handling: Added extensions for case conversion of nullable strings:

  • lowercaseFirstLetter: Lowercases only the first letter of the string, preserving the rest of the case.
  • capitalizeFirstLowerRest: Capitalizes the first letter of the string and lowers the rest.
  • tryToLowerCase: same as the native toLowerCase() but for nullable strings.
  • tryToUpperCase same as the native toUpperCase() but for nullable strings.

• String Utility:

  • isBlank: Alias for isEmptyOrNull, checks if a string is null, empty, or solely whitespace.

• Updated the README.

Initial release of dart_helper_utils, which includes all the Dart utilities from flutter_helper_utils up to version 4.1.0

Added

• ConvertObject class now accepts raw JSON strings for List, Set, and Map conversions, e.g., tryToList<int>("[1,2,3]").
• New TimeUtils class for measuring and comparing execution times, with methods like:
  • executionDuration: Calculates the duration of a task (synchronous or asynchronous).
  • executionDurations: Measures execution times for a list of tasks.
  • compareExecutionTimes: Compares the execution durations of two tasks.
  • throttle: Creates a throttled function that invokes the function at most once per specified interval.
  • runPeriodically: Executes a function periodically with a given interval.
  • runWithTimeout: Executes a function with a timeout, cancelling if it exceeds the specified duration.

Notes

• Future updates and feature changes for Dart-specific utilities will be added to the dart_helper_utils package.
• If you were using Dart-specific utilities from flutter_helper_utils, migrate to dart_helper_utils. If you are using both Flutter and Dart utilities, you can continue using flutter_helper_utils as it exports dart_helper_utils internally.
• This package aims to provide comprehensive Dart utilities for non-Flutter projects.
