#Cg engine plugin android registration#
This registration is done for you automatically with a GeneratedPluginRegistrant, but it is important to understand that every FlutterEngine maintains its own set of Flutter plugins. For example, if a Flutter app requires access to a camera, that capability is achieved by registering a camera plugin with a specific FlutterEngine instance. The fundamental concept of “adding a plugin” to a Flutter app means applying that plugin to a single FlutterEngine. Additionally, an Android app may contain multiple FlutterEngines at the same time.

It also means that a FlutterEngine sets up a number of standard platform channels that all Flutter apps require it includes support for platform views, it knows how to paint a texture with a Flutter UI, and it handles all other fundamental requirements to execute a single Flutter/Dart app. This means that a FlutterEngine controls a Dart isolate (your Dart code that begins with an entrypoint like main). A FlutterEngine object represents a single Flutter execution context. We’ll discuss that API and how to use it.įirst, it is important to understand the FlutterEngine class within the v2 Android embedding. During the development of the v2 Android embedding it became clear that the existing API for Flutter plugins was insufficient to handle the new capabilities of the v2 Android embedding. The v2 Android embedding includes support for standard Android lifecycle events and the separation of Flutter execution from the Android UI, which were missing in the v1 Android embedding. It includes classes like FlutterActivity, FlutterFragment, FlutterView, and FlutterEngine. This is the Android code that is responsible for integrating Flutter within an Android app. In December of 2019, Flutter published a new version of its Android embedding. And finally, we made great strides in testing plugins, with more to come. Furthermore, as we push Flutter to support multiple platforms, we enabled federation, making it possible for multiple teams with different expertise to bring their code together into a seamless experience for the Flutter developer using the plugin. We updated the pubspec.yaml format to make it possible to clearly specify Android and iOS support but also web, macOS, Windows, and Linux. We introduced the Android Plugin API 2.0, which provides a more robust and full-featured way to implement Android support in your plugins.
