   FlutterEngine 的automaticallyRegisterPlugins为true，在FlutterEngine构造方法中会自动调用GeneratedPluginRegistrant.registerWith, 从而将所有plugin都注册到这个FlutterEngine下，FlutterEngine.destroy时会将调用plugin的onDetachedFromEngine方法，这样会影响到一些单例plugin出现异常；例如jpush_flutter

   我也碰到了这个问题，有没有什么好的解决办法啊

   将ForegroundTask的init中创建FlutterEngine(context), 改为FlutterEngine(context, null, false)

   怎么修复啊？FlutterForegroundTask.init方法里没有FlutterEngine(context)参数啊？ flutter_foreground_task: ^9.1.0，

     /// Initialize the [FlutterForegroundTask].
     static void init({
       required AndroidNotificationOptions androidNotificationOptions,
       required IOSNotificationOptions iosNotificationOptions,
       required ForegroundTaskOptions foregroundTaskOptions,
     }) {
       FlutterForegroundTask.androidNotificationOptions =
           androidNotificationOptions;
       FlutterForegroundTask.iosNotificationOptions = iosNotificationOptions;
       FlutterForegroundTask.foregroundTaskOptions = foregroundTaskOptions;
       FlutterForegroundTask.isInitialized = true;
     }

   你都搜错文件了，ForegroundTask.kt这个
