android - Exception has occurred. MissingPluginException (MissingPluginException(No implementation found for method setLibraryNa

I am trying to run my app in Android after implemented the Amplitude in flutter app but when app opens it crashes it exception Exception has occurred. MissingPluginException (MissingPluginException(No implementation found for method setLibraryName on channel amplitude_flutter)) in Android only it is working well in iOS can anyone solve this i really don't know where is the exactly problem is

my main.dart

import 'package:vezigo/Models/app_imports.dart';

@pragma('vm:entry-point')
Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  try {
    await Firebase.initializeApp();
    print("Handling a background message: ${message.messageId}");
  } catch (e) {
    print("Error handling background message: $e");
  }
}

Future<void> _firebaseMessagingAppOpenHandler(RemoteMessage message) async {
  try {
    await Firebase.initializeApp();
    print("Handling a App open message: ${message.messageId}");
  } catch (e) {
    print("Error handling App open message: $e");
  }
}

final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
    FlutterLocalNotificationsPlugin();

void initializeNotifications() async {
  const AndroidInitializationSettings initializationSettingsAndroid =
      AndroidInitializationSettings('');

  final InitializationSettings initializationSettings =
      InitializationSettings(android: initializationSettingsAndroid);

  await flutterLocalNotificationsPlugin.initialize(initializationSettings);
}

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  final prefs = await SharedPreferences.getInstance();
  await prefs.setBool('apiCalledThisLaunch', false);
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );

  FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);
  FirebaseMessaging.onMessageOpenedApp.listen(_firebaseMessagingAppOpenHandler);
  FirebaseMessaging.onMessage.listen((RemoteMessage message) {
    print(
        'Received a message while in the foreground: ${message.notification?.title}');
  });
  SystemChrome.setPreferredOrientations([
    DeviceOrientation.portraitUp,
    DeviceOrientation.portraitDown,
  ]);

  AnalyticsService();
  runApp(
    MultiProvider(
      providers: [
        ChangeNotifierProvider(create: (context) => ProfileProvider()),
        ChangeNotifierProvider(create: (context) => SignupProvider()),
        ChangeNotifierProvider(create: (context) => Cart()),
        ChangeNotifierProvider(create: (context) => AddressProvider()),
        ChangeNotifierProvider(create: (context) => FavoriteProvider()),
      ],
      child: const MyApp(),
    ),
  );
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: ThemeData(

      home: const SplashScreen(),
      routes: {
        '/cart': (context) => const CartScreen(),
      },
    );
