Unable to get token using huawei_push

I have followed the steps in documentation to configure the huawei_push package in plugin. I want to integrate push notification. I am getting error when i use this code

void _onTokenEvent(String event) {
    token = event;
    if (token != null) {
      print("TokenEvent: " + token!);
    }
  }

  void _onTokenError(PlatformException error) {
    print("TokenErrorEvent: " + error.toString());
  }

  static Future<void> getToken() async {
    try {
      Push.enableLogger();

      await Push.getToken("");

      print('Huawei push token ::  ${HosNotificationHelper.token} ');

      Push.disableLogger();
    } catch (e) {
      print(e.toString());
      print('THISIS EXCEPTION');
    }
  }
