Flutter在应用程序前台接收FCM推送通知（iOS）

Question

我正在我的 Flutter 项目中使用 FCM。当应用程序在前台并从 FCM 接收到通知时，我想显示一个 AlertDialog。这个功能在 Android 上可以工作，但在 iOS 上无法正常工作。有谁能帮助我吗？

以下是我的代码片段：

FirebaseMessaging _firebaseMessaging = FirebaseMessaging();
    _firebaseMessaging.configure(
      onMessage: (Map<String, dynamic> message) async {
        print("FCM: onMessage: " + message['notification']['body']);
        //showNotification(message['notification']['title'], message['notification']['body']);
        print("FCM: onMessage: $message");
        setState(() {
          return notification = true;
        });

        AwesomeDialog(
          context: scaffoldKey.currentContext,
          title: message['notification']['title'],
          desc: message['notification']['body'],
          btnOkOnPress: () {
            Navigator.pop(scaffoldKey.currentState.context);
          },
        ).show();

        //notification sound
        playSound();
      },
      onLaunch: (Map<String, dynamic> message) async {
        print("FCM: onLaunch: $message");
      },
      onResume: (Map<String, dynamic> message) async {
        print("FCM: onResume: $message");
      },
    );

    _firebaseMessaging.requestNotificationPermissions(
        const IosNotificationSettings(sound: true, badge: true, alert: true));
    _firebaseMessaging.onIosSettingsRegistered
        .listen((IosNotificationSettings settings) {
      print("Settings registered: $settings");
    });

FCM在前台不会很好地工作，您需要使用其他类似的工具，例如flutter_local_notifications。
