我如何仅使用本地通知并防止使用Firebase Messaging在iOS上使用Flutter上的Firebase Messaging进行自动弹出式

Question

我正在尝试使用iOS设备上的颤音上的本地通知，它可以正常工作，但是该通知弹出窗口两次显示，因为一个来自我的flutterlocalnotificationplugin.show（...），一个是捕获通知时自动显示。

就我而言，我想仅使用局部通知显示通知，因此我必须防止显示自动通知。我试图在没有“通知”对象的情况下发送通知，而只使用“数据”对象发送：在这种情况下，自动通知不会出现，但是未从方法firebasemessaging.onmessage中捕获事件。 listan（（EmeloteMessage Message）异步{...}），因此本地通知也无法正常工作。

在颤音上：

FirebaseMessaging.onMessage.listen((RemoteMessage message) async {


      await FirebaseMessaging.instance
          .setForegroundNotificationPresentationOptions(alert: false);

      FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
          FlutterLocalNotificationsPlugin();

      const IOSInitializationSettings initializationSettingsIOS =
          IOSInitializationSettings();

      final InitializationSettings initializationSettings =
          InitializationSettings(
        iOS: initializationSettingsIOS,
      );
      await flutterLocalNotificationsPlugin.initialize(
        initializationSettings,
        onSelectNotification: (payload) async {
          print("selected");
        },
      );

      Future<String> _downloadAndSaveFile(
          String url, String fileName) async {
        final Directory directory =
            await getApplicationDocumentsDirectory();
        final String filePath = '${directory.path}/$fileName';
        final http.Response response = await http.get(Uri.parse(url));
        final File file = File(filePath);
        await file.writeAsBytes(response.bodyBytes);
        return filePath;
      }

      final String bigPicturePath = await _downloadAndSaveFile(
          message.data['image'], 'bigPicture.jpg');
      final IOSNotificationDetails iOSPlatformChannelSpecifics =
          IOSNotificationDetails(attachments: <IOSNotificationAttachment>[
        IOSNotificationAttachment(bigPicturePath)
      ]);
      NotificationDetails platformChannelSpecifics =
          NotificationDetails(iOS: iOSPlatformChannelSpecifics);
      await flutterLocalNotificationsPlugin.show(0, message.data['title'],
          message.data['body'], platformChannelSpecifics,
          payload: 'item x');
    }

    print("Notification arrived");
  });
}

在服务器上（PHP）：

 $fields = array(

         'notification'    => [
            'content_avaible' => true,
            'body'     => $message,
            'title'    => $title,
            'priority' => "high",
            "image" =>  'image' => "https://foo.bar/image.png"
        ],
        "apns" => [

            "payload" => [
                "aps" => [
                    "mutable-content" => 1
                ]
            ],
            "fcm_options" => [
                 'image' => "https://foo.bar/image.png"
            ]
        ],
        'registration_ids'    => $alltokens,
        'data' => [
            'image' => "https://foo.bar/image.png"
        ],
    );
    $headers = array(
        'Authorization: key=' . API_ACCESS_KEY_IOS,
        'Content-Type: application/json'
    );
    $curlCall = curl_init();
    curl_setopt($curlCall, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
    curl_setopt($curlCall, CURLOPT_POST, true);
    curl_setopt($curlCall, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($curlCall, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curlCall, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curlCall, CURLOPT_POSTFIELDS, json_encode($fields));
    $result = curl_exec($curlCall);
    curl_close($curlCall);
