# android_view
|
||||||
|
|
||||||
|
An example of an Android app that integrates a Flutter add-to-app module at a
|
||||||
|
view level. For more information on how to use it, see the [README](../README.md)
|
||||||
|
file located in the [/add_to_app](/add_to_app) directory of this repo.
|
||||||
|
|
||||||
|
## 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).

*

* 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.
