ios - 如何在 iOS 上使用 Firebase 和 Flutter 获取推送通知？

Question

我尝试了许多不同的教程，例如这个https://medium.com/flutterpub/enabling-firebase-cloud-messaging-push-notifications-with-flutter-39b08f2ed723

但是我无法在我的 iPhone 上接收任何推送通知。它在 Android 上完美运行。

我使用 firebase_messaging:^4.0.0+4 和 flutter_local_notifications:^0.6.1

问题是尽管使用 getToken() 收到 token ，但在 iOS 中没有调用任何监听器(onMessage、onResume 或 onLaunch)

没有错误信息。我找不到这种行为的原因。如果有人能帮助我，我会很高兴。

谢谢。

_firebaseMessaging.configure(
      onMessage: (Map<String, dynamic> message) async {
        print("IM HERE ON MESSAGE");
        print('on message $message');


        String message_as_String = json.encode(message);
        print(message_as_String);
        String title = "test";
        String body = "test";
        String screen = "test";


        var androidPlatformChannelSpecifics = new AndroidNotificationDetails(
            'your channel id', 'your channel name', 'your channel description',
            playSound: false, importance: Importance.Max, priority: Priority.High);
        var iOSPlatformChannelSpecifics =
        new IOSNotificationDetails(presentSound: false);
        var platformChannelSpecifics = new NotificationDetails(
            androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
        await flutterLocalNotificationsPlugin.show(
          0,
          body,
          title,
          platformChannelSpecifics,
          payload: screen,
        );
      },
      onResume: (Map<String, dynamic> message) async {
        print('on resume $message');
        String screen = message["screen"];

      },
      onLaunch: (Map<String, dynamic> message) async {
        print('on launch $message');
      },
    );
    if (Platform.isIOS) iOS_Permission();
    _firebaseMessaging.getToken().then((token){
      print(token);
    });
  }

flutter_local_notifications 的文档说明如下:

NOTE: this plugin registers itself as the delegate to handle incoming notifications and actions. This may cause problems if you're using other plugins for push notifications (e.g. firebase_messaging) as they will most likely do the same and it's only possible to register a single delegate.

几个问题:

• 为什么要同时使用这两个包？
• 您是否在 Xcode 中的 Target 下的 Background Modes 中启用了Remote notifications？
• 您是否为 iOS 上的通知创建了证书？ (APNS:苹果推送通知服务(link)

让我知道你的结果如何 :)
