stop background service is not working

[ranjitIN]

i am using flutter_background_service: 2.4.6 scenario: assume i start a service by clicking of the button and i terminate the app. Now i want to stop the service after reopening the app.

code: Main.dart

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  //initializeService();
  runApp(const MyApp());
}

const notificationChannelId = "conection_service";
const notificationId = 888;

Future<void> initializeService() async {
  final service = FlutterBackgroundService();

  const AndroidNotificationChannel channel = AndroidNotificationChannel(
      notificationChannelId, "Connection Service",
      description: "This channel is used for Connection Service",
      importance: Importance.low,
      playSound: false
      );

  final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
      FlutterLocalNotificationsPlugin();

  await flutterLocalNotificationsPlugin
      .resolvePlatformSpecificImplementation<
          AndroidFlutterLocalNotificationsPlugin>()
      ?.createNotificationChannel(channel);

  await service.configure(
      iosConfiguration: IosConfiguration(),
      androidConfiguration: AndroidConfiguration(
          onStart: onStart,
          isForegroundMode: true,
          notificationChannelId: notificationChannelId,
          initialNotificationTitle: "Connection Service",
          initialNotificationContent: "Initializing",
          foregroundServiceNotificationId: notificationId));
}

// to ensure this is executed
// run app from xcode, then from xcode menu, select Simulate Background Fetch
@pragma('vm:entry-point')
Future<bool> onIosBackground(ServiceInstance service) async {
  WidgetsFlutterBinding.ensureInitialized();
  DartPluginRegistrant.ensureInitialized();
  SharedPreferences preferences = await SharedPreferences.getInstance();
  await preferences.reload();
  final log = preferences.getStringList('log') ?? <String>[];
  log.add(DateTime.now().toIso8601String());
  await preferences.setStringList('log', log);
  return true;
}

@pragma('vm:entry-point')
void onStart(ServiceInstance service) async {
  WidgetsFlutterBinding.ensureInitialized();
  StreamController controller = StreamController();
  int totalconnectedSensors = 0;
  // Only available for flutter 3.0.0 and later
  DartPluginRegistrant.ensureInitialized();
  // For flutter prior to version 3.0.0
  // We have to register the plugin manually

  /// OPTIONAL when use custom notification
  final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
      FlutterLocalNotificationsPlugin();

  if (service is AndroidServiceInstance) {
    service.on('setAsForeground').listen((event) {
      service.setAsForegroundService();
    });

    service.on('setAsBackground').listen((event) {
      service.setAsBackgroundService();
    });
  }

  service.on('stopService').listen((event) {
    service.stopSelf();
  });

  controller.stream.listen((event) {
    flutterLocalNotificationsPlugin.show(
    888,
    'Polar Connection Service',
    'Connected Sensors: $event',
    const NotificationDetails(
      iOS: DarwinNotificationDetails(
          threadIdentifier: "thread1", subtitle: "Service is running"),
      android: AndroidNotificationDetails(
        'Polar Connection Service',
        'Running connection Service',
        icon: 'ic_bg_service_small',
        ongoing: true,
        playSound: false,
      ),
    ),
  );
  });

  Timer.periodic(const Duration(seconds: 1), (timer) async {
    controller.add(totalconnectedSensors++);
    print("Total connectes Sensor $totalconnectedSensors");
  });
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const Home(),
    );
  }
}

calling start service

MaterialButton(
                                  onPressed: () async {
                                    var service = FlutterBackgroundService();
                                    if (await service.isRunning()) {
                                      service.invoke("stopService");
                                    } else {
                                      initializeService();
                                    }
                                  },
                                  color: Colors.blue,
                                  child: const Text(
                                    "Start Service",
                                    style: TextStyle(color: Colors.white),
                                  )),

I have managed by writing line twice

 service.on('stopService').listen((event) {
    service.stopSelf();
    service.stopSelf();
  });
