How to store data after 24 hours in flutte?r / How to update UI after some time when app is closed/k-CodePudding

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 not the count the time when app is close it only work when *application is open. *

Can anyone please tell me that how can we execute the function after a specific time even app is close?

*Here is my 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.
