如何在FlutterbackgroundServices方法中接收插座事件[Flutter]

Question

我正在使用节点JS中的服务器运行socket.io，我想做的是，当应用程序在后台时，它仍然从插座接收事件，只能发送事件，但不会接收事件。

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  socketConnection.socket.connect();
  await FlutterBackgroundService.initialize(onStart); //here start executing the onStart method
  runApp(MyApp());
}


onStart() async {
  WidgetsFlutterBinding.ensureInitialized();
  final service = FlutterBackgroundService();
  if (await service.isServiceRunning()) {
    socketEvents();//socket events method
  }
}

socketEvents() {
  log(socketConnection.socket.connected.toString()); //here I want to know if it is connected and it always shows me **false**, but it does connect
  socketConnection.socket.on('noty_event', (data) async {
    log(data['msg'].toString()); //I want to show in the console when an event arrives but it does not show anything
  });
}
