I am making an app with flutter. I want to store data after 24 hours and update UI in app. I try with Timer.periodic() but it does not count the time when app is close. It only works when the application is open.

Is it possible to execute a function after a specific time even if the app is closed?

Here is my current code:

void callbackDispatcher() async{
  Workmanager().executeTask((task, inputData) {
    switch(sdDaily){
      case 'StoreDataDaily':
       storeData.storeDailyData();
        break;
      default:
    }
    return Future.value(true);
  });
}

void main() async{
  WidgetsFlutterBinding.ensureInitialized();
  Directory directory = await path_provider.getApplicationDocumentsDirectory();
  print(directory.path);
  Hive.init(directory.path);
  await Hive.initFlutter(directory.path);
  Hive.registerAdapter(UserAdapter());
  Hive.registerAdapter(WaterAdapter());
  Hive.registerAdapter(WeekAdapter());
  Get.put(UserController());
  Get.put(WaterController());
  await Hive.openBox<User>('data');
  await Hive.openBox<Water>('water_data');
  await Hive.openBox<Week>('week_data');
  await notificationPlugin.showNotification();
  await Workmanager().initialize(callbackDispatcher, isInDebugMode: true);
  var uniqueId = DateTime.now().second.toString();
  var userBox = Hive.box<User>('data');
  if(userBox.get(0)?.status == 1){
    await Workmanager().registerOneOffTask(uniqueId, sdDaily,);
  }

  runApp(const MyApp());
}

You can use : flutter_background_service. to execute background services and it'll also help you sending a custom notification when you are actually going to store that data later.

You can use firebase cloud funcitons to do schedule tasks or whatever you want to do even if app is closed or killed.
