dart-flutter-patterns SKILL.md skillA
dart-flutter-patterns from affaan-m/ecc is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add affaan-m/ecc/dart-flutter-patterns@git:20260517.ec9ace9Pins git:20260517.ec9ace9 in mdr.lock. Pin the fingerprint instead.

本番環境対応のDartおよびFlutterパターンは、null安全性、不変状態、非同期構成、ウィジェットアーキテクチャ、人気のある状態管理フレームワーク（BLoC、Riverpod、Provider）、GoRouterナビゲーション、Dioネットワーキング、Freezedコード生成、クリーンアーキテクチャをカバー。.
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パターン
## 使用時期
次の場合にこのスキルを使用：
- 新しいFlutter機能を開始し、状態管理、ナビゲーション、またはデータアクセスのイディオマティックパターンが必要
- Dartコードのレビューまたは作成とnull安全性、シール型、非同期構成のガイダンスが必要
- 新しいFlutterプロジェクトをセットアップしBLoC、Riverpod、またはProviderのうち選択
- 安全なHTTPクライアント、WebView統合、ローカルストレージを実装
- FlutterウィジェットEt、Cubit、またはRiverpodプロバイダーのテストを作成
- GoRouterを認証ガードでワイヤリング
## 動作方法
このスキルは、懸念事項で整理されたコピーペーストの準備ができたDart/Flutterコードパターンを提供：
1. **Null安全性** — `!`を避ける、`?.`/`??`/パターンマッチングを好む
2. **不変状態** — シール型、`freezed`、`copyWith`
3. **非同期構成** — 並行`Future.wait`、`await`後の安全な`BuildContext`
4. **ウィジェットアーキテクチャ** — クラスに抽出（メソッドではなく）、`const`伝播、スコープ付きリビルド
5. **状態管理** — BLoC/Cubityベント、Riverpodノーティファイアおよび派生プロバイダー
6. **ナビゲーション** — `refreshListenable`経由の反応型認証ガード付きGoRouter
7. **ネットワーキング** — インターセプタ付きDio、ワンタイム再試行ガード付きトークンリフレッシュ
8. **エラーハンドリング** — グローバルキャプチャ、`ErrorWidget.builder`、crashlyticsワイヤリング
9. **テスト** — ユニット（BLoC test）、ウィジェット（ProviderScopeオーバーライド）、モック上のフェイク
## 例
```dart
// シール状態 — 不可能な状態を防止
sealed class AsyncState<T> {}
final class Loading<T> extends AsyncState<T> {}
final class Success<T> extends AsyncState<T> { final T data; const Success(this.data); }
final class Failure<T> extends AsyncState<T> { final Object error; const Failure(this.error); }

How to install
mdr add affaan-m/ecc/dart-flutter-patterns@sha256:6deb8f8377fe0219The line at the top of this page pins the label git:20260517.ec9ace9, 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.
