Flutter: Hive database is working well but when restarting the app the data is disappeared

[MohammadSamiAbdelfattah]

This is Hive setup in main function that I open a box and also put the registerAdapter as I said in the question that everything is okay but when restarting the app data lost

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await Hive.initFlutter();

  Hive.registerAdapter(QuestionModelAdapter());
  await Hive.openBox<QuestionModel>("saveQuestion");

  runApp(const MyApp());
}

This is the class I used in hive class.

import 'package:hive/hive.dart';

part 'question.g.dart';

@HiveType(typeId: 0)
class QuestionModel {
  @HiveField(0)
  String title;

  @HiveField(1)
  List<dynamic> options;

  QuestionModel({
    required this.title,
    required this.options,
  });
}

Version

• Platform: Android
• Flutter version: [2.0.0]
• Hive version: [2.0.4]

this two function solves void _eventBoxPutter() async { await _eventBox.put(_eventKey, _events); refreshItems(); }

/// this refresh items by getting again from box void refreshItems() { _events = _eventBox.get(_eventKey) ?? {}; _recycleEvents = _deletedBox.get(_deletedEventKey) ?? <Event>[]; selectedDay.refresh(); update(); }

The same issue is happening also with simple String objects, where an adapter is not needed.
