未处理的异常：MissingPluginException（在通道 Awesome_notifications 上找不到方法初始化的实现）

我已经在 main.dart 中初始化了 Awesome_notifications 插件当我热重启时，在调试控制台中我收到此错误：

    E/flutter ( 4447): [ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: MissingPluginException(No implementation found for method initialize on channel awesome_notifications)
E/flutter ( 4447): #0      MethodChannel._invokeMethod

这是我的代码：

主程序.dart

Future<void> main() async {
  WidgetsFlutterBinding();
  await Hive.initFlutter();
  if (!Hive.isAdapterRegistered(AddEventModelAdapter().typeId)) {
    Hive.registerAdapter(AddEventModelAdapter());
  }
  AwesomeNotifications()
      .initialize('resource://drawable/res_notification_app_icon', [
    NotificationChannel(
      channelKey: 'schedule_channel',
      channelName: 'scheduled_channel',
      channelDescription: 'descroiption',
      locked: true,
      importance: NotificationImportance.High,
    ),
  ]);

  runApp(const MyApp());
}

每当您在 pubspec.yaml 中添加插件时，您需要停止应用程序并重新运行再次因为该插件包含两个平台上的本机代码。

如果还是不行，那就执行 flutter clean 并运行。
