flutter SKILL.md skillA

flutter from lynricsy/hyperskills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add lynricsy/hyperskills/flutter@v2026.10.15

Pins v2026.10.15 in mdr.lock. Pin the fingerprint instead.

Develops cross-platform Flutter apps with Dart, widgets and state management.

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

## Scope

Covers Flutter application and Dart package work: widget composition and layout,
the three state-management stacks in real use, navigation and deep links,
testing at every layer, performance, localization, networking and
serialization, Dart 3 language features, analyzer/tooling hygiene, and the
Dart↔native boundary (platform channels, Pigeon, FFI).

Not covered: writing native iOS/Android UI or platform SDK code beyond the
channel boundary — use the `apple` or `android` skill. Other cross-platform
stacks: React Native and Expo belong to the `react-native` skill. Also out of
scope: Flutter web hosting/CI/store release, Firebase and other vendor SDKs,
and game engines (Flame). For visual/UX design decisions or web frontends, use
the `frontend-design` skill instead.

Paths below are relative to this skill's directory.

## Core rules

1. Detect the stack before touching state: read `pubspec.yaml`. `flutter_riverpod` /
   `hooks_riverpod` / `riverpod_annotation` → Riverpod; `flutter_bloc` → Bloc/Cubit;
   neither → `ChangeNotifier` + `ListenableBuilder`. Two state solutions in one app
   means two sources of truth for the same screen.

How to install

The exact contents, by fingerprint

mdr add lynricsy/hyperskills/flutter@sha256:a495ea1310feef6d

The line at the top of this page pins the label v2026.10.15, 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.
