The method 'onSelectNotifications' isn't defined using flutter local notification plugin

Question

in flutter_local_notification 12.0.2

The onSelectNotification parameter is not anymore. So what is the alternative of this. So that we can handle callback when we click on notification.

Answer 1

you can stream the notification

import 'package:rxdart/rxdart.dart';
...
// use this 
class MyNotifManager {
static final onNotifications = BehaviorSubject<String?>();
...

// then add the payload to your local notification
// exampel for  the foreground notif

  onDidReceiveNotificationResponse: (payload) async {
        onNotifications.add(payload.payload); // add payload to the stream
  },

then to handle the callback:

Future<void> listenNotification() async =>
      MyNotifManager.onNotifications.stream.listen(onClickNotification);

and for your action after click

void onClickNotification(String? payload) {
  Navigator.push();
}

call the stream on your initState

@override
  void initState() {
    super.initState();
    MyNotifManager.init();
    listenNotification();
  }

with this method, you will able to handle calback when click on notification.

Answer 2

It has onDidReceiveNotificationResponse callback when plugin initialize.

    _plugin.initialize(
      initializationSettings,
      onDidReceiveNotificationResponse: (details) {
          // Click Notification Event Here
      },
    );

If you click notification when app is terminated,

    _plugin.getNotificationAppLaunchDetails().then((value) {
         // Click Notification Event Here
    });
