I/flutter (13346): [ion-sdk-flutter] ERROR: onnegotiationneeded: e => Bad state: No element

Your environment.

• Package Version: 0.4.4
• System: Android
• Android Version : Android 10 (API 29) & Android 11 (API 30)

What did you do?

I wanted to only run this application with audio and not with video, so I changes the _localStream from

_localStream = await LocalStream.getUserMedia(
              constraints: Constraints.defaults
                ..simulcast = false
                ..resolution = resolution
                ..codec = codec);

to

_localStream = await LocalStream.getUserMedia(
              constraints: Constraints(
            audio: true,
            video: false,
            codec: codec,
          ));

but this isn't working. And it's showing me this error:

I/flutter (13346): [ion-sdk-flutter] ERROR: onnegotiationneeded: e => Bad state: No element

Also, I've made some changes in the code based on this like in ion?.onTrack function

track.kind=='audio' 

rather than

track.kind=='video'

What did you expect?

I expected a black screen instead of video stream (which was there) and the audio stream to work fine (but it did not).

What happened?

Instead it didn't stream any audio and showing me this:
