[AchmadSyarippudin]

What happened?

I want navigate to specific page when notification was click.

so I added this code :

"OneSignal.Notifications.addClickListener((OSNotificationClickEvent event) {
print(event.notification.additionalData);
})"

Steps to reproduce?

1. onesignal Version 5.2 
2. Degugging on android emulator 
3. add this code "OneSignal.Notifications.addClickListener((OSNotificationClickEvent event) {
      print(event.notification.additionalData);
    });"
4. restart /  hot reload application
5. check console log data was print as many times as app gets hot restarted

What did you expect to happen?

my expectation "print" only appears when I was clicked notification.
