How to reproduce?

The callback is triggered twice for "update" events and four times for "insert" events.

      PhotoManager.addChangeCallback(changeNotify);
      PhotoManager.startChangeNotify();

void changeNotify(MethodCall call) {
   print("CHANGED");
   print(call.toString());
}

AI Summary: The changeNotify callback is triggered multiple times (twice for updates, four times for inserts) for a single media insert or update event on Android. This indicates a potential issue with the PhotoManager package's change notification mechanism, causing duplicate notifications.

If you are still seeing multiple calls using the unmodified example of this library, that would be the problem of the device, otherwise we should look into it.
