java.lang.IllegalArgumentException：服务未注册：ls@1ff721a

如何解决java.lang.IllegalArgumentException：服务未注册：ls@1ff721a

我正在使用 firebase_messaging 7.0.3 和 flutter_local_notifications 4.0.0 在 android 中发送通知，一切正常，我也使用 sqlite 来保存通知，除非后台模式我可以看到通知来，否则它仍然可以正常工作但看起来像我为保存通知而创建的函数没有调用。

代码句柄通知

    _firebaseMessaging.configure(
  onBackgroundMessage: Platform.isIOS ? null : myBackgroundMessageHandler,onMessage: (Map<String,dynamic> message) async {
    MessageNotification notification = MessageNotification(
        id: null,title: message['notification']['title'],body: message['notification']['body'],status: 'U',createdDate: formatted);
    await dbHelper.save(notification);

    showNotification(
        message['notification']['title'],message['notification']['body']);
    messages = await dbHelper.getMessages();
    if (messages.isEmpty) {
      messages = [];
    }
    update();

    print("onLaunch: $message");
  },onLaunch: (Map<String,dynamic> message) async {
    print("onLaunch: $message");
    showNotification(
        message['notification']['title'],message['notification']['body']);
  },onResume: (Map<String,dynamic> message) async {
    print("onResume: $message");
    showNotification(
        message['notification']['title'],message['notification']['body']);
    messages = await dbHelper.getMessages();
    update();
  },);

}

代码处理后台保存

Database db;
const String ID = 'id';
const String TITLE = 'title';
const String BODY = 'body';
const String STATUS = 'status';
const String CREATEDDATE = 'createdDate';
const String TABLE = 'Message';
const String DB_NAME = 'message2.db';
Future<dynamic> myBackgroundMessageHandler(Map<String,dynamic> message) async {
  print('on background running');
  MessageNotification notification = MessageNotification(
      id: null,title: "Hello",body: "hello",createdDate: "2020-10-2020");

  await db.insert(TABLE,notification.toMap());


  return Future<void>.value();

  // Or do other work.
}

应用程序.java

public class Application extends FlutterApplication implements PluginRegistrantCallback {
@Override
public void onCreate() {
    super.onCreate();
    FlutterFirebaseMessagingService.setPluginRegistrant(this);
}

@Override
public void registerWith(PluginRegistry registry) {
    FirebaseMessagingPlugin.registerWith(registry.registrarFor("io.Flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
    FlutterlocalnotificationsPlugin.registerWith(registry.registrarFor("com.dexterous.Flutterlocalnotifications.FlutterlocalnotificationsPlugin"));
    PathProviderPlugin.registerWith(registry.registrarFor("io.Flutter.plugins.pathprovider.PathProviderPlugin"));
    SqflitePlugin.registerWith(registry.registrarFor("com.tekartik.sqflite.SqflitePlugin"));
}

}
