+ * [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.

+ * 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
