Interface PluginRegistry

All Known Implementing Classes:

FlutterActivity, FlutterActivityDelegate, FlutterFragmentActivity, FlutterPluginRegistry, ShimPluginRegistry

public interface PluginRegistry

Container class for Android API listeners used by ActivityPluginBinding.

This class also contains deprecated v1 embedding APIs used for plugin registration.

In v1 Android applications, an auto-generated and auto-updated plugin registrant class (GeneratedPluginRegistrant) makes use of a PluginRegistry to register contributions from each plugin mentioned in the application's pubspec file. The generated registrant class is, again by default, called from the application's main Activity, which defaults to an instance of FlutterActivity, itself a PluginRegistry.
