我正在使用flutter应用程序上的firebase_messaging包，它可以完美地工作，除了当应用程序在后台，我得到一个通知，它只打开应用程序，从来没有做什么，我要求它打开应用程序后做。

Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  // If you're going to use other Firebase services in the background, such as Firestore,
  // make sure you call `initializeApp` before using other Firebase services.
  await Firebase.initializeApp();

  print("Handling a background message: ${message.messageId}");
  final dynamic data = message.data;
  print("data is $data");
  if(data.containsKey('request_id')) {
    print("we are inside ..!");
    RegExp exp = RegExp(r'\d+');
    var id = int.parse(exp.firstMatch(data['request_id']!)!.group(0)!);
    OpenRequestsController openRequestsController = Get.isRegistered<OpenRequestsController>()?Get.find():Get.put(OpenRequestsController());
    OpenRequest matchingRequest = openRequestsController.openRequestsList.firstWhere((request) => request.id == id);
    print("the request from the list is $matchingRequest");
    openRequestsController.openRequestDetails(matchingRequest,false);

  }
}

这里发生的是，它试图运行整个功能时，消息被接收，而不是当点击。和ofc它失败，因为应用程序还没有在前台运行
