2026-10-13 errors flutter flutter-3-47

Fix: pubspec.lock shows as modified after flutter upgrade or switching Flutter versions

The Flutter SDK pins versions of meta, vector_math, test_api and matcher, so every SDK change re-resolves your lockfile, and flutter upgrade runs pub upgrade on the project you stand in. Pin one Flutter version per repo and enforce the lockfile in CI.

2026-10-02 errors flutter flutter-3-44

Fix: Undefined name 'awaitNotRequired' from material_ui or cupertino_ui on Flutter 3.44

material_ui 1.3.0 and cupertino_ui 1.1.0 use an annotation Flutter 3.44 does not export. Both are retracted, but a lockfile keeps them. Downgrade, then upgrade, to land on 1.2.0 and 1.0.2.
