Flutter engineering

Skill HeyEddi-com/skills/evals/runs/2026-07-04T22-58-59Z/flutter-backend-bridger-users/.cursor/skills/flutter-engineering

Ensures HeyEddi Flutter projects have the right engineering stack — Flutter (Riverpod, go_router, Material 3), FastAPI backend, or Firebase tooling. Audits gaps, scaffolds as needed, runs flutter test/analyze, documents local dev servers. Use when frontend is Flutter or before design/feature work on a HeyEddi mobile/web app.From its SKILL.md

Flutter Engineering

Baseline Flutter engineering for HeyEddi apps. Detects which stacks apply and adds the correct tooling — Vue projects should use @project-engineering instead.

Subagents (default)

Delegate scaffold/audit/test scripts to Task shell; repo discovery to explore. Main chat picks stack from audit JSON. See reference/subagents.md.

Stacks

Stack	When	Tooling added
Flutter	Mobile / web frontend	`pubspec.yaml`, Riverpod, go_router, Material 3, widget tests
FastAPI	REST API backend	`backend/`, pytest, `openapi.json`, uvicorn on 8090
Firebase	Firestore / Auth	`firebase.json`, rules, emulators

Declare intent in .heyeddi/stack.json:

{
  "frontend": "flutter",
  "backends": ["fastapi"],
  "web_port": 8085,
  "api_port": 8090
}

Or "backends": ["firebase"] or ["fastapi", "firebase"].

Workflow

audit_scaffold — per-layer JSON (flutter / fastapi / firebase).
scaffold_stack --stack auto — fills gaps (flutter, fastapi, firebase, or full).
ensure_flutter + ensure_python (via @project-engineering) as needed.
dev_server_info — Flutter web :8085, API :8090, Firebase emulators :4000.
Implement features (@design-handoff-flutter, @flutter-patterns, @dart-type-bridger).
run_tests + run_backend_tests + verify_build.

Local dev servers

Stack	Command	URL
Flutter web	`flutter run -d web-server --web-port=8085 --web-hostname=127.0.0.1`	http://127.0.0.1:8085
Flutter mobile	`flutter run`	device / emulator
FastAPI	`cd backend && poetry run uvicorn app.main:app --reload --port 8090`	http://127.0.0.1:8090/docs
Firebase	`firebase emulators:start`	http://localhost:4000

Set FLUTTER_WEB_URL (or DEV_SERVER_URL) for @visual-auditor when auditing Flutter web.
