*
* Omitted features from the [io.flutter.embedding.android.FlutterActivity] include:
* * **State restoration**. If you're integrating at the view level, you should handle activity
* state restoration yourself.
* * **Engine creations**. At this level of granularity, you must make an engine and attach.
* and all engine features like initial route etc must be configured on the engine yourself.
* * **Splash screens**. You must implement it yourself. Read from
* `addOnFirstFrameRenderedListener` as needed.
* * **Transparency, surface/texture**. These are just [FlutterView] level APIs. Set them on the
* [FlutterView] directly.
* * **Intents**. This doesn't do any translation of intents into actions in the [FlutterEngine].
* you must do them yourself.
* * **Back buttons**. You must decide whether to send it to Flutter via
* [FlutterEngine.getNavigationChannel.popRoute()], or consume it natively. Though that
* decision may be difficult due to https://github.com/flutter/flutter/issues/67011.
* * **Low memory signals**. You're strongly encouraged to pass the low memory signals (such
* as from the host `Activity`'s `onTrimMemory` callbacks) to the [FlutterEngine] to let
* Flutter and the Dart VM cull its own memory usage.
*
* Your own [FlutterView] integrating application may need a similar wrapper but you must decide on
* what the appropriate intersection between the [FlutterView], the [FlutterEngine] and your
* `Activity` should be for your own application.

# flutter_module_using_plugin
An example Flutter module that uses a native plugin, intended for use in the
Flutter add-to-app samples. For more information on how to use it, see the
[README.md](../README.md) parent directory.
## Getting Started
For more information about Flutter, check out
[flutter.dev](https://flutter.dev).
For instructions on how to integrate Flutter modules into your existing
applications, see Flutter's
[add-to-app documentation](https://flutter.dev/docs/development/add-to-app).
