点按的弹出式本地通知无法正常工作

Question

我使用Flutter_isolate包在后台处理本地通知。 一切都很好，将显示通知弹出窗口。但是，当我点击弹出通知时，什么也没有发生（没有错误显示）。有人可以帮助我处理点击本地通知事件吗？

无错误显示。在调试模式下没有任何反应

Future<bool> _showNotification(Event event) async {
    FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
    new FlutterLocalNotificationsPlugin();
    var initializationSettingsAndroid = new AndroidInitializationSettings('app_icon');
    var initializationSettingsIOS = new IOSInitializationSettings();
    var initializationSettings = new InitializationSettings(
    initializationSettingsAndroid, initializationSettingsIOS);
    flutterLocalNotificationsPlugin.initialize(initializationSettings,
    onSelectNotification: onSelectNotification);
    var androidPlatformChannelSpecifics = AndroidNotificationDetails(
   'CHANNEL ID', 'CHANNEL NAME', 'CHANNEL DESCRIPTION',sound: 'message_vocal_rdv',importance: Importance.Max,
  priority: Priority.High);
  var iOSPlatformChannelSpecifics = new IOSNotificationDetails(sound: "slow_spring_board.aiff");
  var platformChannelSpecifics = NotificationDetails(
  androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
  await flutterLocalNotificationsPlugin.show(0, 'Octogone Group', 'Notification rendez-vous', platformChannelSpecifics,
  payload: 'Hello Word');
  return true;
}
Future onSelectNotification(String payload) async {
   if (payload != null) {
      debugPrint('payload is' + payload);}
  await _navigationService.navigateTo(
  NotificationDetailsRoute, arguments: payload);
}
