[Bug]: Push Notification Modification at run time is not working

[FakharAlyas119]

What happened?

I am trying to modify the notification title and the body at run time and pass that OSNotification object to notificationEvent.complete(modified) but it's not working it shows the old notification the one without modification
I am using onesignal_flutter: ^3.5.1

Steps to reproduce?

1. install onesignal_flutter: ^3.5.1
2. push your notification from the dashboard
3. when you receive a notification at the mobile end modify it like this
    final modified = osNotificationModifier.toOpportunityLaunchNotification(
          notification,
          obj: toAppNotification,
        );
   toAppNotification is my object toOpportunityLaunchNotification function successfully returns the new OSNotification
4.  notificationEvent.complete(modified);
    this will show the un-modified notification

What did you expect to happen?

It should show the modified notification, but it shows an un-modified notification

Hi @FakharAlyas119, thanks for reporting.

1. Can you share VERBOSE level logs starting right before the notification is received?
2. Are you making a new OSNotification object and passing it into complete?
3. Can you try modifying the OSNotification received in the event and passing that to complete and seeing what happens?

setNotificationWillShowInForegroundHandler does not support modifying the notification. It only support omitting the notification.

We will consider this a feature request.

A workaround in the meantime is you can call complete(null) and display your own local notification.
