MuhammedKpln commented 1 year ago

I don't think this issue is package related. Try to add flutter_webrtc as your dependency and try again.

garv-shah commented 1 year ago

Yeah, I tried that and it didn't help. I presumed it would be package related since the traceback links to the peerdart package

MuhammedKpln commented 1 year ago

Peerdart basically is a wrapper around flutter webrtc, and MissingPluginException is well when Flutter does not find its native modules. Have a look at flutter_webrtc GitHub page and see if you can find something.
