Create, evolve, test, or prepare reusable Dart packages and Flutter plugins for distribution. Use when the package itself, its public API, platform support, federation, example app, compatibility, or publication readiness is the deliverable; route app-owned native bridges to flutter-platform-integration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Flutter Package Development Treat reusable packages as versioned contracts consumed by independent projects. Preserve SDK bounds, package architecture, supported platforms, and release conventions unless migration is requested. ## Preflight Inspect `pubspec.yaml`, public exports, examples, tests, platform folders, CI, changelogs, and consumers. Choose the smallest viable shape: - Dart package for reusable Dart-only logic. - Flutter package for reusable widgets without native code. - Plugin or FFI package when native platform implementations are required. - Federated plugin only when independent platform ownership or release cadence justifies multiple packages. Do not convert app-owned bridges into packages merely because code reuse is possible. ## Load references conditionally - Read [public API and package quality](references/public-api-and-quality.md) for exports, deprecations, semver, and consumer compatibility. - Read [plugins and federation](references/plugins-and-federation.md) for platform interfaces, registration, FFI, and federated architecture. …

How to install
mdr add thiennc-tesoglobal/flutter-skills/flutter-package-development@sha256:e5e11341a72fd406The line at the top of this page pins the label git:20261103.d4e0895, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
