registerCallback not working in flutter 3.29 and flutter_downloader 1.12.0

I initialize on main.dart the plugin. In a streamstore I create the receivePort and IsolateNameServer. After that add the listen of port and add registercallback above. In 1.11.8 was working, in 1.12.0 the callback is not working.

Start with main.dart and reproduce the callback setup using Flutter 3.29 with flutter_downloader 1.12.0, comparing it against 1.11.8. Inspect the streamstore receivePort, IsolateNameServer, listen, and registerCallback sequence. Done means the registered callback is invoked again with version 1.12.0.
