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.
