Production-ready Dart and Flutter patterns covering null safety, immutable state with Freezed, async composition, widget architecture, state management (BLoC, Riverpod, Provider), GoRouter navigation with auth guards, Dio networking, error handling, and testing. Use when writing or reviewing Dart and Flutter code — state, widgets, navigation, networking, or architecture.
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
# Dart/Flutter Patterns ## When to Use Use this skill when: - Starting a new Flutter feature and need idiomatic patterns for state management, navigation, or data access - Reviewing or writing Dart code and need guidance on null safety, sealed types, or async composition - Setting up a new Flutter project and choosing between BLoC, Riverpod, or Provider - Implementing secure HTTP clients, WebView integration, or local storage - Writing tests for Flutter widgets, Cubits, or Riverpod providers - Wiring up GoRouter with authentication guards ## How It Works This skill provides copy-paste-ready Dart/Flutter code patterns organized by concern: 1. **Null safety** — avoid `!`, prefer `?.`/`??`/pattern matching 2. **Immutable state** — sealed classes, `freezed`, `copyWith` 3. **Async composition** — concurrent `Future.wait`, safe `BuildContext` after `await` 4. **Widget architecture** — extract to classes (not methods), `const` propagation, scoped rebuilds 5. **State management** — BLoC/Cubit events, Riverpod notifiers and derived providers 6. **Navigation** — GoRouter with reactive auth guards via `refreshListenable` …

How to install
mdr add wankimmy/bossku-superpowers/dart-flutter-patterns@sha256:43b6e45cc3f15d8dThe line at the top of this page pins the label git:20261012.feb2361, 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.
