Dart Type Bridger

When to use

  • Flutter agent needs accurate API payload shapes
  • Local openapi.json (or another OpenAPI file under the project root)
  • Firestore rules or schema file exists for Firebase projects

Instructions

  1. Ensure a local OpenAPI file at openapi.json. Prefer the scaffolded file. If the API is running and the file is missing/stale, export to disk first (do not pass a URL into this skill):

    curl -fsS http://127.0.0.1:8090/openapi.json -o openapi.json
    
  2. FastAPI models: python scripts/sync_openapi.py --project-root <root>: writes lib/models/api_models.dart from local openapi.json only (optional --openapi path/rel.json).

  3. Firebase: python scripts/fetch_firestore_schema.py --project-root <root>

  4. Import generated models in repositories: never guess field names.
