如何在 Flutter 中使用最新版本配置 Firebase 消息传递

发布于12月08日

我使用下面一行代码进行Firebase消息传递配置和Flutter 通知配置，但是现在在集成到最新版本的Firebase消息传递后，它给出了错误

代码行

 messaging.configure(onMessage: (Map<String, dynamic> message){}

DART分析中出错

error: The method 'configure' isn't defined for the type 'FirebaseMessaging'.

推荐答案

请判断以下示例.

https://github.com/FirebaseExtended/flutterfire/blob/master/packages/firebase_messaging/firebase_messaging/example/lib/main.dart

  @override
  void initState() {
    super.initState();
    FirebaseMessaging.instance
        .getInitialMessage()
        .then((RemoteMessage message) {
      if (message != null) {
        Navigator.pushNamed(context, '/message',
            arguments: MessageArguments(message, true));
      }
    });

    FirebaseMessaging.onMessage.listen((RemoteMessage message) {
      RemoteNotification notification = message.notification;
      AndroidNotification android = message.notification?.android;

      if (notification != null && android != null) {
        flutterLocalNotificationsPlugin.show(
            notification.hashCode,
            notification.title,
            notification.body,
            NotificationDetails(
              android: AndroidNotificationDetails(
                channel.id,
                channel.name,
                channel.description,
                // TODO add a proper drawable resource to android, for now using
                //      one that already exists in example app.
                icon: 'launch_background',
              ),
            ));
      }
    });

    FirebaseMessaging.onMessageOpenedApp.listen((RemoteMessage message) {
      print('A new onMessageOpenedApp event was published!');
      Navigator.pushNamed(context, '/message',
          arguments: MessageArguments(message, true));
    });
  }
