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

When the task is complete: suggest next skills
When you have finished the user's request for this skill (not after every tool call or subagent phase), suggest what to run next:
Run:
python .agents/skills/heyeddi-orchestrator/scripts/suggest_next_skill.py --current-skill flutter-engineering --project-root .
Add --route /path if you worked a specific route.
Include the script's ### Next step block in your final reply. The user copies the Prompt line into chat (e.g. @heyeddi-design craft /settings).
Pass --mode shape (or craft, audit, etc.) when you know which sub-command just finished.
See @heyeddi-orchestrator → reference/next-skill-handoff.md.
1---2name: flutter-engineering-23description: Ensures HeyEddi Flutter projects have the right engineering stack: Flutter (Riverpod, go_router, Material 3), FastAPI backend, or Firebase tooling.
