Encountered Error Running Waterbus App

[Aziiz777]

Description:
I encountered the following error when running the Waterbus app. I'm unsure of the root cause, but I suspect it may be related to the version of flutter_webrtc inside the Waterbus Flutter SDK package.

Error Log:

the error is very long , appearing in nearly every WebRTC Java file. Due to its length, I won't be able to post it here.

any solution for this ?
