flutter-webrtc
Microphone not working in iOS simulators after upgrading to version 1.0.0
Describe the bug After upgrading to version 1.0.0, the microphone no longer works using flutter_webrtc in the iOS Simulator. Reverting back down to 0.14.2 causes it work work again. Do double-check, going back to version 1.0.0 reintroduces the problem.
Possibly related to #1909 , which was also introduced in 1.0.0
To Reproduce Upgrade to package version 1.0.0 and try the microphone with webrtc.
Expected behavior The microphone should work as it does with version 0.14.2 and prior.
Platform information Release build on physical iOS device.

A working microphone is very important for developing with webrtc and not being able to use the iOS simulator greatly hampers our iOS side development. We would like to not be stuck on version 0.14.2.
