| # Windows Platform Embedder |
| |
| This code is the glue between the Flutter engine and the Windows platform. |
| It is responsible for: |
| |
| 1. Launching the Flutter engine. |
| 2. Providing a view for the Flutter engine to render into. |
| 3. Dispatching events to the Flutter engine. |
| |
| For more information on embedders, see the |
| [Flutter architectural overview](https://docs.flutter.dev/resources/architectural-overview). |
| |
| > [!CAUTION] |
| > This is a best effort attempt to document the Windows embedder. It is not |
| > guaranteed to be up to date or complete. If you find a discrepancy, please |
| > [send a pull request](https://github.com/flutter/engine/compare)! |
