Updates Windows engine's data structures to use a map of views. This is a refactoring with no semantic changes. Flutter Windows's APIs restrict users to 0 or 1 view only - it is not possible to create multiple views yet. _One small step for Windows. One giant leap for multi-view._ Part of https://github.com/flutter/flutter/issues/143765 Part of https://github.com/flutter/flutter/issues/142845 [C++, Objective-C, Java style guides]: https://github.com/flutter/engine/blob/main/CONTRIBUTING.md#style
Windows Platform Embedder
This code is the glue between the Flutter engine and the Windows platform. It is responsible for:
- Launching the Flutter engine.
- Providing a view for the Flutter engine to render into.
- Dispatching events to the Flutter engine.
For more information on embedders, see the Flutter 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!
