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 6 versions: 3 breaking change, 1 removed, 17 bug fix.
4 high-impact items. Start with: Scribble Text Input Client; Raw images on Web uses correct origin and colors; Required Kotlin version; ….
Read the 3 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.
Adds three methods, `showToolbar`, `insertTextPlaceholder`, and `removeTextPlaceholder` to the `TextInputClient` interface to allow the iOS 14 Scribble feature to insert and remove text placeholders and show the toolbar.
How raw images are rendered on Web has been corrected and is now consistent with that on other platforms. This breaks legacy apps that had to feed incorrect data to `ui.ImageDescriptor.raw` or `ui.decodeImageFromPixels`, causing the resulting images to be upside-down and incorrectly colored (whose red and blue channels are swapped.)
To build a Flutter app for Android, Kotlin 1.5.31 or greater is required.
In accordance with Flutter's Deprecation Policy, deprecated APIs that reached end of life after the 2.5 stable release have been removed.
