androidNotificationCallback gets called for unrelated notifications

[pkuzco]

androidNotificationCallback gets called when clicking notifications that are shown by other flutter plugins. A payload/id (String) should be passed to androidNotificationCallback, so we are able to tell whether this was triggered as a result of clicking this plugin's foreground service notification or some other unrelated notification.

How to reproduce?

1. Show some notification using flutter_local_notifications
2. Click on that shown notification from (1)
3. androidNotificationCallback will be called even though the notification was not shown by background_locator.

That's really really strange, can you create a simple project to test this?

I think you need to specify a unique action name when you build an Intent for notification, and then check that you got that specific action before calling androidNotificationCallback; similar to what flutter_local_notifications is doing:
