方法"get"不是为在 Flutter 中使用 Hive 的类型'Object'定义的

Question

当我试图通过使用Hive库从WordPress网站缓存新闻时，我正面临着这种问题，我在代码中得到了这个问题，方法'get'没有为'Object'类型定义"箱子吗?。获得";．这是我第一次在Flutter上使用Hive如何解决这个问题?

import 'package:hive_flutter/hive_flutter.dart';
import 'package:hive/hive.dart';
const String SETTINGS_BOX = "settings";
const String API_BOX = "api_data";
///
Future main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
await SystemChrome.setPreferredOrientations([
DeviceOrientation.portraitUp,
DeviceOrientation.portraitDown,
]);
SystemChrome.setSystemUIOverlayStyle(
const SystemUiOverlayStyle(
statusBarColor: Color(0xFF0D47A1),

),
);
setupLocator();
await Hive.initFlutter();
await Hive.openBox(SETTINGS_BOX);
await Hive.openBox(API_BOX);
runApp(MyApp());
}
/// ignore: must_be_immutable
class MyApp extends StatelessWidget {
late final List<Article> posts;
var data;
@override
Widget build(BuildContext context) {
print(Hive.box(SETTINGS_BOX).get("welcome_shown"));
return ValueListenableBuilder(
valueListenable: Hive.box(SETTINGS_BOX).listenable(),
builder: (context, box, child) => box?.get('welcome_shown', defaultValue: false)
? HomePage()
: MultiProvider(
providers: [
Provider(create: (context) => FavoriteListModel()),
ChangeNotifierProxyProvider<FavoriteListModel, FavoritePageModel>(
create: (context) => FavoritePageModel(),
update: (context, favoritelist, favoritepage) {
if (favoritepage == null) {
throw ArgumentError.notNull('favoritepage');
}
favoritepage.favoritelist = favoritelist;
return favoritepage;
},
),
],
child: MaterialApp(
initialRoute: "/splashScreen",
routes: {
"/splashScreen": (_) => SplashScreen(),
"/presentationScreens": (_) => OnboardingScreens(),
"/homepage": (_) => HomePage(),
},
),
),
);
}
}

您是否注册了盒子适配器?

await Hive.initFlutter();
Hive.registerAdapter(<YOUR ADAPTER>);
