@override
Future<void> popRoute() {
  Completer<void> completer = Completer();
  String uuid = Uuid().v4();
  String receiverKey = 'pop_route_response';
  receiverMap[receiverKey] = (key, data) {
    receiverMap.remove(receiverKey);
    completer.complete();
  };
  communicationDelegate?.sendMessage("pop_route_request_$uuid", null);
