How to use Flutter Method Channel in background (app minimised/closed)

I am collecting information/discussion that redirects us to run flutter engine in background.

void callbackDispatcher() {WidgetsFlutterBinding.ensureInitialized();print("Our background job ran!");

}

void main() { static const MethodChannel _channel = const MethodChannel("channel-name"); Future<void> initialize(final Function callbackDispatcher) async {  final callback = PluginUtilities.getCallbackHandle(callbackDispatcher); await _channel.invokeMethod('initialize', callback.toRawHandle()); }}

As stated here How to run Flutter in the background?

When a background job is started by native the Flutter engine is not active. So we are unable to run Dart.Can Android/iOS starts the Flutter engine in the background?Yes! We’ll first need to register a Dart callback function which will only be invoked whenever a background job is started by the native code.This callback function is referred to as a callbackDispatcher.

Also please check out these stackoverflow discussions.
