# Flutter — SDK detail

Official docs are the **Flutter client SDK** (`launchdarkly_flutter_client_sdk`). Use a **mobile key** for typical **iOS, Android, and desktop app** builds; use a **Client-side ID** (and public env naming for web) for **Flutter web**. Multi-target apps: see [Generate integration plan](../../../sdk-install/plan/SKILL.md).

**Primary:** [Flutter SDK reference](https://launchdarkly.com/docs/sdk/client-side/flutter) — `pubspec`, initialization, and API.

**Also useful:**

- pub.dev: [launchdarkly_flutter_client_sdk](https://pub.dev/packages/launchdarkly_flutter_client_sdk)
- GitHub: [flutter-client-sdk](https://github.com/launchdarkly/flutter-client-sdk)
- Example app: [flutter_client_sdk example](https://github.com/launchdarkly/flutter-client-sdk/tree/main/packages/flutter_client_sdk/example)
- API docs: [Flutter SDK API](https://pub.dev/documentation/launchdarkly_flutter_client_sdk/latest/)
