3. **Set Up Environment Variables**:
- Copy the `.env.example` file to create a new `.env` file:
- Client config is compile-time via `--dart-define-from-file` (not a bundled `.env` asset).
- Copy the example file and fill in **client-safe** values only:
```
cp .env.example .env
```
- Update the `.env` file with your Supabase credentials (as described in the BACKEND.md guide):
```

GEMINI_API_KEY=<YOUR_GEMINI_API_KEY>

coderabbitai[bot] marked this conversation as resolved.
- Do **not** put `SUPABASE_SERVICE_ROLE_KEY` in `dart_defines.json` (server-only).
- `dart_defines.json` is gitignored.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Complete the Dart define migration in this guide.

The setup now uses dart_defines.json, but SupabaseService is still documented as loading environment variables at Line 232, the troubleshooting step still points to .env at Line 338, and the iOS release command at Line 307 omits --dart-define-from-file=dart_defines.json. Users following those steps can start the app without required AppConfig values. Update these instructions and all iOS build and run commands.

As per path instructions, documentation examples must match the codebase.

Keep GEMINI_API_KEY out of the Flutter client.

AppConfig.geminiApiKey is compiled into the app, and AIService sends it directly to Gemini. Route chat requests through a server-side endpoint and keep the key in server secrets. Remove GEMINI_API_KEY from client configuration examples and requirements.
