Interface ActivityPluginBinding

public interface ActivityPluginBinding

Binding that gives ActivityAware plugins access to an associated Activity and the Activity's lifecycle methods.

Method Details

getActivity

@NonNull
Activity getActivity()

Returns the Activity that is currently attached to the FlutterEngine that owns this ActivityPluginBinding.

getLifecycle

@NonNull
Object getLifecycle()

Returns the Lifecycle associated with the attached Activity.

Use the flutter_plugin_android_lifecycle plugin to turn the returned Object into a Lifecycle object. See (https://github.com/flutter/plugins/tree/master/packages/flutter_plugin_android_lifecycle). Flutter plugins that rely on Lifecycle are forced to use the flutter_plugin_android_lifecycle plugin so that the version of the Android Lifecycle library is exposed to pub, which allows Flutter to manage different versions library over time.
