- Fully migrated core cherrypick_generator and submodules to new analyzer element2 system:
- Updated all GeneratorForAnnotation overrides to use Element2, ClassElement2, MethodElement2, FieldElement2 and new annotation/metadata access patterns.
- Migrated signature and bodies for helpers, parsers, annotation validators, meta utils, and type parsers.
- Fixed tests to use readerWriter instead of deprecated reader argument.
- Refactored usage of now-absent 'metadata', 'parameters', 'fields', 'methods', 'source', and similar members to use correct *.firstFragment.* or API alternatives.
- Cleaned up old imports and unused code.
test(generator): update generator integration tests
- Updated test calls to use correct TestReaderWriter type and bring test infra in line with current build_runner/testing API.
build: update dependencies and pubspec to support latest analyzer/build ecosystem
- Raised Dart SDK and package constraints as required for generated code and codegen plugins.
- Updated pubspecs in root/examples as needed by build warnings.
docs: add plots and assets (new files)
BREAKING CHANGE:
- Requires Dart 3.8+ and analyzer that supports element2.
- All downstream codegen/tests depending on Element API must migrate to Element2 signatures and data model.
