Detailed Description

Resources made available to all plugins registered with a given io.flutter.embedding.engine.FlutterEngine.

The provided BinaryMessenger can be used to communicate with Dart code running in the Flutter context associated with this plugin binding.

Plugins that need to respond to Lifecycle events should implement the additional io.flutter.embedding.engine.plugins.activity.ActivityAware and/or io.flutter.embedding.engine.plugins.service.ServiceAware interfaces, where a Lifecycle reference can be obtained.

getApplicationContext()

Context io.flutter.embedding.engine.plugins.FlutterPlugin.FlutterPluginBinding.getApplicationContext ( )

getBinaryMessenger()

BinaryMessenger io.flutter.embedding.engine.plugins.FlutterPlugin.FlutterPluginBinding.getBinaryMessenger ( )

                                                {
      return binaryMessenger;
    }

getEngineGroup()

FlutterEngineGroup io.flutter.embedding.engine.plugins.FlutterPlugin.FlutterPluginBinding.getEngineGroup ( )

inline

Accessor for the FlutterEngineGroup used to create the FlutterEngine for the app.

This is useful in the rare case that a plugin has to spawn its own engine (for example, running an engine the background). The result is nullable since old versions of Flutter and custom setups may not have used a FlutterEngineGroup. Failing to use this when it is available will result in suboptimal performance and odd behaviors related to Dart isolate groups.
