Choose two real stable releases. Boring Doc lists every indexed change between them with its evidence, impact and migration instructions, and can fetch the verified source diff from GitHub.
21 indexed changes across 4 versions: 8 breaking change, 1 removed, 1 deprecated api, 11 bug fix.
9 high-impact items. Start with: Default drag scrolling devices; Change the enterText method to move the caret to the end of the input text; GestureRecognizer cleanup; ….
Read the 8 official migration guides first, apply `dart fix` where available, then upgrade and run your test suite. Deprecations can be scheduled; removals cannot.
Prefer stepping through stable series sequentially; each breaking-change page has a checklist, before/after code and the official guide. Verify with `flutter analyze`, `flutter test` and a profile-mode run on each target platform.
Tick “Fetch verified source diff” above (or load it now) to corroborate these announcements with the git history between the two tags.
`ScrollBehavior`s now allow or disallow drag scrolling from specified `PointerDeviceKind`s. `ScrollBehavior.dragDevices`, by default, allows scrolling widgets to be dragged by all `PointerDeviceKind`s except for `PointerDeviceKind.mouse`.
The `WidgetTester.enterText` and `TestTextInput.enterText` methods now move the caret to the end of the input text.
`OneSequenceGestureRecognizer.addAllowedPointer()` was changed to take a `PointerDownEvent`, like its superclass. Previously, it accepted the more general `PointerEvent` type, which was incorrect.
The `package:flutter_lints` defines the latest set of recommended lints that encourage good coding practices for Flutter apps, packages, and plugins. Projects created with `flutter create` using Flutter version 2.5 or newer are already enabled to use the latest set of recommended lints. Projects created prior to that version can upgrade to it with the instructions in this guide.
The `AnimationSheetBuilder.display` and `sheetSize` methods are deprecated, and should be replaced with `AnimationSheetBuilder.collate`.
The following methods have been replaced by APIs in the `flutter_test` package:
Flutter now renders all web platform views in a consistent location of the DOM, as direct children of `flt-glass-pane` (regardless of the rendering backend: `html` or `canvaskit`). Platform views are then _"slotted"_ into the correct position of the App's DOM with standard HTML features.
