Error with recording on ios Simulator when using any encorder as an input option

[Infinitism]

Describe the bug
Anytime I try to enable a different encoding with the controller constructor, the waveforms don't show up on recording and doesn't record at all. When I remove the encoder options, it works.

To Reproduce
Steps to reproduce the behavior:

1. Recording with ONLY this constructor works:

recorderController = RecorderController()

2. Change to following where encoder is literally anything as given in the documentation, and it stops working.

_recorderController = RecorderController()
..androidEncoder = AndroidEncoder.amr_wb
..iosEncoder = IosEncoder.kAudioFormatAMR_WB
..sampleRate = 16000;

Expected behavior
Should record audio when using different encoders.

Smartphone (please complete the following information):
ios simnulator: 15 pro max

Additional context
I need to use one of the encoding formats listed on this Google Speech to Text documentation and, though the options exist for constructor, won't work when provided one.

Hello @Infinitism can you please check whether the encoder is supported by the platform or not? If supported, then please share the encoder format.
