Question

我已使用 flutter_local_notifications ，推送通知已成功接收，当我单击它时，我试图重定向到特定屏幕，但它始终重定向到主屏幕。

下面是我的代码。

@override
void initState() {
  // TODO: implement initState
  super.initState();

  // initialise the plugin. app_icon needs to be a added as a drawable resource to the Android head project
  var initializationSettingsAndroid =
      new AndroidInitializationSettings('app_icon');
  var initializationSettingsIOS = new IOSInitializationSettings();
  var initializationSettings = new InitializationSettings(
      initializationSettingsAndroid, initializationSettingsIOS);
  flutterLocalNotificationsPlugin.initialize(initializationSettings,
      onSelectNotification: onSelectNotification);

  _firebaseMessaging.configure(
    onMessage: (Map<String, dynamic> message) {
      print('on message $message');

      var data = message['data'] as Map;
      var msg1 = data['message'] as String;
      var response = json.decode(msg1) as Map;

      String str_title = response['title'] as String;
      String str_body = response['body'] as String;

      _showNotification(str_title, str_body, msg1);
    },
    onResume: (Map<String, dynamic> message) {
      print('on resume $message');
    },
    onLaunch: (Map<String, dynamic> message) {
      print('on launch $message');
}

_showNotification功能代码

void _showNotification(String title, String body, String pay_load) async {
    var androidPlatformChannelSpecifics = new AndroidNotificationDetails(
    AppConstant.notify_channel_id,
    AppConstant.notify_channel_name,
    AppConstant.notify_channel_desc,
    importance: Importance.Max,
    priority: Priority.High);
    var iOSPlatformChannelSpecifics = new IOSNotificationDetails();
    var platformChannelSpecifics = new NotificationDetails(
    androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
    await flutterLocalNotificationsPlugin
    .show(0, title, body, platformChannelSpecifics, payload: pay_load);
}

onSelectNotification功能代码

Future onSelectNotification(String payload) async {
  if (payload != null) {
    debugPrint('notification payload: ' + payload);
  }

  // here set and put condition for property id
  var response = json.decode(payload) as Map;

  Navigator.push(
    context,
    MaterialPageRoute(
        builder: (context) =>
            PropertyDetailScreen()),
);

PropertyDetailScreen 是我在单击通知时要重定向的屏幕，但是它始终重定向到主屏幕，因此请指导我哪里我出错了，或者为什么我的代码不起作用。

按以下说明使用GlobalKey尝试

在内部声明

class _MyAppState extends State<MyApp> {
    final GlobalKey<NavigatorState> navigatorKey = GlobalKey(debugLabel: "MainNavigator");
    }

在MaterialApp中分配

MaterialApp(
              navigatorKey: navigatorKey,
              supportedLocales: [
                Locale('en', 'US'),
                Locale('ar', ''),
                Locale('it'),
                Locale('fr'),
                Locale('es'),
                Locale('de'),
                Locale('pt'),
              ],
    );

用作navigatorKey.currentState.push(MaterialPageRoute(builder: (context) => YourClassName()));

Flutter-推送通知点击重定向到特定屏幕不起作用
