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.
37 indexed changes across 10 versions: 6 breaking change, 2 removed, 1 deprecated api, 28 bug fix.
8 high-impact items. Start with: Added missing dispose() for some disposable objects in Flutter; Added AppLifecycleState.hidden; Moved ReorderableListView's localized strings; ….
Read the 6 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.
A source diff proves code changed; it does not by itself show that a public API is breaking. Use it to corroborate the announcements above.
Missing calls to 'dispose()' are added for some disposable objects. For example, ContextMenuController did not dispose OverlayEntry, and EditableTextState did not dispose TextSelectionOverlay.
A new `hidden` state was added to the `AppLifecycleState` enum to denote when the application is not visible.
`ReorderableListView`'s localized strings were moved from material localizations to widgets localizations. These strings were deprecated in material localizations.
The `Editable.onCaretChanged` callback is removed. With this change, `EditableText` behavior for scrolling the selection into view changes.

The `IgnoringPointer` widget allows you to designate an area of the UI where you don't want to accept pointer events, for example, when you don't want to allow the user to enter text in a text field.
`RouteInformation.location` and related APIs were deprecated in the favor of `RouteInformation.uri`.
