- Method Detail
  - activity
```
Activity activity()
```
    Deprecated.
    
    Returns the Activity that forms the plugin's operating context.
    Plugin authors should not assume the type returned by this method is any specific subclass of Activity (such as FlutterActivity or FlutterFragmentActivity), as applications are free to use any activity subclass.
    When there is no foreground activity in the application, this will return null. If a Context is needed, use context() to get the application's context.
    This registrar is for Flutter's v1 embedding. To access an Activity from a plugin using the v2 embedding, see ActivityPluginBinding.getActivity(). To obtain an instance of an ActivityPluginBinding in a Flutter plugin, implement the ActivityAware interface. A binding is provided in ActivityAware.onAttachedToActivity(ActivityPluginBinding) and ActivityAware.onReattachedToActivityForConfigChanges(ActivityPluginBinding).

  - context
```
Context context()
```
    Deprecated.
    
    Returns the Application's Context.
    This registrar is for Flutter's v1 embedding. To access a Context from a plugin using the v2 embedding, see FlutterPlugin.FlutterPluginBinding#getApplicationContext()
    For instructions on migrating a plugin from Flutter's v1 Android embedding to v2, visit http://flutter.dev/go/android-plugin-migration
  - activeContext
```
Context activeContext()
```
    Deprecated.
    
    Returns the active Context.
    This registrar is for Flutter's v1 embedding. In the v2 embedding, there is no concept of an "active context". Either use the application Context or an attached Activity. See context() and activity() for more details.
    For instructions on migrating a plugin from Flutter's v1 Android embedding to v2, visit http://flutter.dev/go/android-plugin-migration
    
    Returns:
    
    the current Activity, if not null, otherwise the Application.
  - messenger
```
BinaryMessenger messenger()
```
    Deprecated.
    
    Returns a BinaryMessenger which the plugin can use for creating channels for communicating with the Dart side.
    This registrar is for Flutter's v1 embedding. To access a BinaryMessenger from a plugin using the v2 embedding, see FlutterPlugin.FlutterPluginBinding#getBinaryMessenger()
    For instructions on migrating a plugin from Flutter's v1 Android embedding to v2, visit http://flutter.dev/go/android-plugin-migration
  - textures
```
TextureRegistry textures()
```
    Deprecated.
    
    Returns a TextureRegistry which the plugin can use for managing backend textures.
    This registrar is for Flutter's v1 embedding. To access a TextureRegistry from a plugin using the v2 embedding, see FlutterPlugin.FlutterPluginBinding#getTextureRegistry()
    For instructions on migrating a plugin from Flutter's v1 Android embedding to v2, visit http://flutter.dev/go/android-plugin-migration
  - platformViewRegistry
```
PlatformViewRegistry platformViewRegistry()
```
    Deprecated.
    
    Returns the application's PlatformViewRegistry.
    Plugins can use the platform registry to register their view factories.
    This registrar is for Flutter's v1 embedding. To access a PlatformViewRegistry from a plugin using the v2 embedding, see FlutterPlugin.FlutterPluginBinding#getPlatformViewRegistry()
    For instructions on migrating a plugin from Flutter's v1 Android embedding to v2, visit http://flutter.dev/go/android-plugin-migration
  - view
```
FlutterView view()
```
    Deprecated.
    
    Returns the FlutterView that's instantiated by this plugin's activity.
    This registrar is for Flutter's v1 embedding. The FlutterView referenced by this method does not exist in the v2 embedding. Additionally, no View is exposed to any plugins in the v2 embedding. Platform views can access their containing View using the platform views APIs. If you have a use-case that absolutely requires a plugin to access an Android View, please file a ticket on GitHub.

  - lookupKeyForAsset
```
String lookupKeyForAsset(String asset)
```
    Deprecated.
    
    Returns the file name for the given asset. The returned file name can be used to access the asset in the APK through the AssetManager API.
    TODO(mattcarroll): point this method towards new lookup method.
    
    Parameters:
    
    asset - the name of the asset. The name can be hierarchical
    
    Returns:
    
    the filename to be used with AssetManager
  - lookupKeyForAsset
```
String lookupKeyForAsset(String asset,
                         String packageName)
```
    Deprecated.
    
    Returns the file name for the given asset which originates from the specified packageName. The returned file name can be used to access the asset in the APK through the AssetManager API.
    TODO(mattcarroll): point this method towards new lookup method.
    
    Parameters:
    
    asset - the name of the asset. The name can be hierarchical
    
    packageName - the name of the package from which the asset originates
    
    Returns:
    
    the file name to be used with AssetManager
  - publish
```
PluginRegistry.Registrar publish(Object value)
```
    Deprecated.
    
    Publishes a value associated with the plugin being registered.
    The published value is available to interested clients via PluginRegistry.valuePublishedByPlugin(String).
    Publication should be done only when client code needs to interact with the plugin in a way that cannot be accomplished by the plugin registering callbacks with client APIs.
    Overwrites any previously published value.
    This registrar is for Flutter's v1 embedding. The concept of publishing values from plugins is not supported in the v2 embedding.

  - addRequestPermissionsResultListener
```
PluginRegistry.Registrar addRequestPermissionsResultListener(PluginRegistry.RequestPermissionsResultListener listener)
```
    Deprecated.
    
    Adds a callback allowing the plugin to take part in handling incoming calls to Activity#onRequestPermissionsResult(int, String[], int[]) or androidx.core.app.ActivityCompat.OnRequestPermissionsResultCallback#onRequestPermissionsResult(int, String[], int[]).
    This registrar is for Flutter's v1 embedding. To listen for permission results in the v2 embedding, use ActivityPluginBinding.addRequestPermissionsResultListener(PluginRegistry.RequestPermissionsResultListener).

```
    Deprecated.
    
    Adds a callback allowing the plugin to take part in handling incoming calls to Activity.onActivityResult(int, int, Intent).
    This registrar is for Flutter's v1 embedding. To listen for Activity results in the v2 embedding, use ActivityPluginBinding.addActivityResultListener(PluginRegistry.ActivityResultListener).
    For instructions on migrating a plugin from Flutter's v1 Android embedding to v2, visit http://flutter.dev/go/android-plugin-migration
    
    Parameters:

    For instructions on migrating a plugin from Flutter's v1 Android embedding to v2, visit http://flutter.dev/go/android-plugin-migration
    
    Parameters:
    
    listener - a PluginRegistry.NewIntentListener callback.
    
    Returns:
    
    this PluginRegistry.Registrar.
  - addUserLeaveHintListener
```
PluginRegistry.Registrar addUserLeaveHintListener(PluginRegistry.UserLeaveHintListener listener)
```
    Deprecated.
    
    Adds a callback allowing the plugin to take part in handling incoming calls to Activity.onUserLeaveHint().
    This registrar is for Flutter's v1 embedding. To listen for leave hints in the v2 embedding, use ActivityPluginBinding.addOnUserLeaveHintListener(PluginRegistry.UserLeaveHintListener).

    Parameters:
    
    listener - a PluginRegistry.UserLeaveHintListener callback.
    
    Returns:
    
    this PluginRegistry.Registrar.
  - addViewDestroyListener
```
PluginRegistry.Registrar addViewDestroyListener(PluginRegistry.ViewDestroyListener listener)
```
    Deprecated.
    
    Adds a callback allowing the plugin to take part in handling incoming calls to Activity.onDestroy().
    This registrar is for Flutter's v1 embedding. The concept of View destruction does not exist in the v2 embedding. However, plugins in the v2 embedding can respond to ActivityAware.onDetachedFromActivityForConfigChanges() and ActivityAware.onDetachedFromActivity(), which indicate the loss of a visual context for the running Flutter experience. Developers should implement ActivityAware for their FlutterPlugin if such callbacks are needed. Also, plugins can respond to FlutterPlugin.onDetachedFromEngine(FlutterPlugin.FlutterPluginBinding), which indicates that the given plugin has been completely disconnected from the associated Flutter experience and should clean up any resources.
    For instructions on migrating a plugin from Flutter's v1 Android embedding to v2, visit http://flutter.dev/go/android-plugin-migration
    
    Parameters:
    
    listener - a PluginRegistry.ViewDestroyListener callback.
    
    Returns:
    
    this PluginRegistry.Registrar.
