flutter_reorderable_grid_view 5.5.2

flutter_reorderable_grid_view: ^5.5.2 copied to clipboard

🐛 Bug Fixes

• fixed an issue where reordering stopped working after changing device orientation

🏄‍♂️ Improvements

• Updated not recommended MediaQuery calls:
  • MediaQuery.of(context).size → MediaQuery.sizeOf(context)
  • MediaQuery.of(context).orientation → MediaQuery.orientationOf(context)
• Thanks to hajajmaor for reporting this! (#163)

🐛 Bug Fixes

• forgotten assert in the builder constructor was added (thanks to FaFre, see #159)
• added mounted check before calling .forward() to prevent AssertionError (thanks hajajmaor, see #158)

🏄‍♂️ Improvements

• default value of automaticScrollExtent updated to 150.0 (was previously 80.0)
• updated README to clarify when to use a ScrollController (see #152)
• general code refactoring
• added new parameter onReorderedPositions
  • similar to onReorder, but allows you to handle reordering logic yourself
  • thanks to FaFre for the PR (#153)

🐛 Bug Fixes

• fixed an issue in Reorderable.builder when removing children
  • the error occurred because reordering finished with items outside the index
  • fixed by adding a new parameter itemCount to ReorderableBuilder.builder
  • this value ensures only rendered children are used for reordering
  • thanks to yoyoNTNU for identifying the issue (#155)

🐛 Bug Fixes

• when dragging an item to a DragTarget widget, the onDragEnd callback was not being called, causing the reorder process to remain incomplete
  • fixed it by using the onDragCompleted callback of Draggable
  • added a new example file: drag_target_example.dart

🐛 Bug Fixes

• dragging is now restricted to a single contact at a time
  • previously, initiating a drag with multiple contacts was possible, but only one contact would be dragged
  • this issue has been resolved to prevent confusion
  • special thanks to wuhangandroid and Gloomy699 (#57)
• Fixed issue with longPressDelay set to Duration.zero or enableLongPress set to false (#141)
  • Previously, child widgets with an onTap function wouldn't respond
  • This should now work correctly, but note that using a delay of less than 55ms may still cause the issue

⭐️ New Features

• added a generic type for ReorderableBuilder
  • eliminates the need to cast reorderListFunction in onReorder
  • special thanks to KevenMelo (#142)

ℹ️ Information

• added a new example for DefaultTabController
  • it was unclear how the ReorderableBuilder works with DefaultTabController and TabBarView
  • special thanks to isenbj and emavgl (#78)

🐛 Bug Fixes

• fixed reordering issue:
  • reordering didn't work correctly after adding a new item
  • special thanks to OICQ469 (#135)
• fixed fade in
  • the fade in didn't appear when a new child was added

🐛 Bug Fixes

• fixed PageView.builder issues:

  • resolved problems when using PageView.builder, improving stability during reordering
  • special thanks to FanYuanBo888 (#121) and billizzard2 (#113) for reporting and contributing

• resolved reordering issue with scrolling:

  • fixed a bug where scrolling to the top while dragging and then back to the bottom caused issues with reordering children
  • thanks to davidmartos96 for identifying this issue (#127)

• fixed drag and drop after resizing:

  • addressed an issue where drag and drop would stop working correctly after resizing the grid
  • acknowledgements to khjde1207 for the report (#91)

⭐️ New Features

• added parameter reverse
  • if your GridView uses the flag reverse, ensure to also use it for ReorderableBuilder
• improved the scrolling behavior while dragging

⭐️ New Features

• enhanced the visual appearance of the feedback widget when starting a drag
• improved behavior when enableLongPress is set to false:
  • previously, the feedback widget only appeared after moving the dragged widget
  • now, the feedback starts immediately when pressing the widget, as LongPressDraggable is consistently used whether enableLongPress is true or false
  • this change also deprecates enableLongPress, as it's no longer needed. To achieve the same effect as enableLongPress = false, simply set longPressDelay to Duration.zero

🐛 Bug Fixes

• Fixed an issue where dragging didn't work correctly with CarouselSlider (thanks to charmosz – Issue #118).
  • The solution ensures the scroll position of the ScrollController is always used when it's added to ReorderableBuilder and linked to a scrollable widget.

• there were performance issues (Issue #107)
  • because setState was called many times, it rerendered all children
  • I improved it by only rendering the updated children when they are built
  • this version can be used to test it

🐛 Bug fix

• Dragging not working in release mode on Android (thanks to shubham-gupta-16 - Issue #105)
  • changed behavior of Listener to HitTestBehavior.deferToChild

This release introduces a complete overhaul of the package, delivering significant performance optimizations, bug fixes, and new features.

⭐️ New features

• Improved Reorderable.builder performance: Now only renders visible children, similar to GridView.builder, significantly enhancing performance
• Horizontal direction support (Issue #53):
  • GridView now supports both horizontal and vertical directions
• New fadeInDuration parameter (Issue #68):
  • Default: 500ms
  • Controls the animation duration when a new child appears
• Draggable and LongPressDraggable now support data attachment
• New onDraggedChildUpdated callback (thanks for the PR Bader-AI):
  • Called whenever a dragged child updates its position during dragging
  • Avoid modifying children during this callback to prevent erratic behavior
• New releasedChildDuration parameter:
  • Defines the duration for a child to settle into its new position after being released
  • Default 150ms
• New positionDuration parameter (thanks to naderhezzy - Issue #94):
  • Adjusts the animation duration when a child's position changes (e.g., when adding/removing items)
• New nonDraggableIndicies parameter (thanks to Bader-Al for the PR #93):
  • Specifies indices of non-draggable items, though they remain movable while dragging other items

⚡️ Breaking Changes

• onReorder function now includes a reorder callback that must be invoked within the onReorder handler
  • This improves performance, especially when working with large lists
  • Refer to the updated examples for guidance
• onDragStarted and onDragEnd callbacks now include the index of the dragged child in their parameters

🐛 Bug fix

• locked children were still draggable, now they are locked (thanks to gmarizy - Issue #97)

🐛 Bug fixes

• fixed issue when deleting the dragged child (thanks to khjde1207 - Issue #88)

⭐️ New features

• added parameter positionDuration (thanks to naderhezzy - Issue #94)
  • changes the animation duration when a child updates his position e.g. when adding or removing a child
• added parameter nonDraggableIndicies (thanks to Bader-Al for the PR #93)
  • you can specify the indices of children that cannot be dragged but are still movable while dragging

🐛 Bug fixes

• fixed animation when releasing a dragged item
• fixed item animations when adding or removing them

⭐️ New features

• you can add data to Draggable or LongPressDraggable
  • use the widget CustomDraggable for that
  • more info is added to the read me
• added new callback onDraggedChildUpdated (thanks for the PR Bader-AI)
  • always called when the dragged child updated his position while dragging
  • you should use this without changing the children, otherwise this could lead to weird behavior while using drag and drop
• added new parameter releasedChildDuration
  • can be used to define the duration when a dragged child was released and is moving to his new position
  • default value is 150ms

🐛 Bug fixes

• there were issues that required to add initDelay to fix wrong behavior while drag and drop
  • this should be fixed by calculating the positions differently to before
  • before the positions were calculated related to the global widget
  • now the positions are only calculated to the local widget
  • this fixes wrong calculated positions
  • fixes issue of naw2nd in Issue #83 when using a BottomModalSheet

🐛 This release contains some bugfixes (optimization)

• while dragging there were issues when the user scrolled with another finger
  • the dragged item was dropped if when it shouldn't

🐛 This release contains some bugfixes

• fixed drag and drop after using functionality "scrolling while dragging" (thanks to tsquillario for pointing out that issue)
• fixed disappeared children after using functionality "scrolling while dragging"

⭐️ New features

• updated two functions
  • onDragStarted
    • added index to parameter
    • index is the index where the drag started
  • onDragEnd
    • added index to parameter
    • index is the index where the drag ended

🐛 This release contains some bugfixes

• onDragStarted wasn't called and should work now
• onDragEnd wasn't called and should work now

⭐️ New features

• added support for horizontal direction (Issue #53)
  • with this, you can use your GridView in both directions
  • currently there might be still small bugs
• added parameter fadeInDuration (Issue #68)
  • default value is const Duration(milliseconds: 500)
  • this parameter is responsible for the animation when a new child appears and describes the duration of the animation
• parameter initDelay is working again

• 🐛 This release contains some bugfixes
  • drag and drop combined with lockedIndices and GridView.builder should work now
• ⭐️ Optimized reordering items
  • the callback onReorder is offering a function as parameter after reordering items
  • the reason for that change is a performance issue, especially having big lists
  • to ensure that everyone is using the same reordering process, I moved the logic to the package inside a function
• 🧑‍💻
  • refactored some code and added comments to some parts
