I was also struggling a lot to handle push notification when app is killed, eventually I got the solution.

If we really observe carefully we don't need to register headless task because the package react-native-firebase is already handling it.

All we have to do is add the following lines in your MainActivity.java on native side.

@Override
public void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    setIntent(intent);
    intent.putExtras(this.getIntent());
}

I have a git repo link of mine which has complete set up of notifications, works in all cases i.e, foreground, background, Even app is killed.

See We really don't need that RNFirebaseBackgroundMessage (headlessTask), Without that we can handle the notifications in all cases i.e, foreground, background, App killed. That's what I put in my case(above link) – UPPALAPU VENKATESH Sep 30 '19 at 12:10
