The sample corpus

Every sample in src/data/samples/ is complete, self-contained Dart that passed flutter analyze with zero errors/warnings in a scratch app before landing here (test-category samples also pass flutter test). Categories: rendering, animation, architecture, async, platform, navigation, performance, testing, ui-patterns, and connectivity (BLE, MQTT, provisioning, serial, firmware↔app protocol, OTA — the device-companion layer for REC's embedded products).

Setup

git clone https://github.com/RoanokeControls/flutter-coder.git
cd flutter-coder
npm install
npm run build
npm test        # corpus integrity suite

Register in Claude Code

Add to ~/.claude.json under mcpServers:

{
  "flutter-coder": {
    "type": "stdio",
    "command": "node",
    "args": ["/path/to/flutter-coder/dist/index.js"]
  }
}

Or copy .mcp.json to your Flutter project root for project-level registration.

Staying current

npm run check-updates probes Flutter/Dart releases and the tracked pub.dev packages against the committed baseline in data/version-state.json, exiting 1 when static content may be stale. A scheduled cloud routine runs it on the 1st of every month and opens a GitHub issue with the findings. See CLAUDE.md for the maintenance playbook.

    └── patterns.ts           # State management patterns + codegen templates
scripts/check-updates.mjs     # Monthly freshness probe (exit 1 = actionable)
data/version-state.json       # Committed baseline the probe diffs against
test/corpus.test.mjs          # Integrity suite (ids, categories, deprecated-API bans)

Hybrid approach: live fetching from official APIs (pub.dev, api.flutter.dev, api.dart.dev, docs.flutter.dev) combined with curated, analyzer-verified static data for samples, error solutions, and guidance. All live fetches use an in-memory TTL cache.
