chore: update Flutter to 3.38.1 and bump Dart SDK versions

- Update Flutter version from 3.32.0 to 3.38.1 in .fvmrc
- Bump Dart SDK minimum version in pubspec.yaml files:
  - Root: 3.2.0 -> 3.8.0
  - cherrypick_annotations: 3.8.0 -> 3.9.0
  - cherrypick/example: 2.12.0 -> 3.2.0
  - examples/postly: 3.8.0 -> 3.9.0
- Apply code formatting fixes in cherrypick_generator
- Update dependencies in pubspec.lock files
