How to save a List<Object> and retrieve using Hive?

Step 1: Add those dependencies on pubspec.yaml file

dependencies:
  hive: ^2.2.3
  hive_flutter: ^1.1.0

dev_dependencies:
  hive_generator: ^1.1.3
  build_runner: ^[latest version]

Step 2: Make the class like this

part 'wallpaper.g.dart';

@HiveType(typeId: 0, adapterName: "WallpaperAdapter")
class Wallpaper{

  @HiveField(0)
  final String date;

  @HiveField(1)
  final String url;

  Wallpaper({required this.date, required this.url});

}

Step 3: Run the command on terminal

1. flutter packages pub run build_runner build

                      or

2. flutter packages pub run build_runner watch --delete-conflicting-outputs

Step 4: Now register the adapter on main.dart

  void main() async {

  WidgetsFlutterBinding.ensureInitialized();
  await Hive.initFlutter();
  Hive.registerAdapter(WallpaperAdapter());
  await Hive.openBox('myBox');

  runApp(MyApp());
}

Step 5: Now restart your application and let's enjoy 😊
