The data specified for the media type is invalid, inconsistent

Describe the bug

        const encoder = AudioEncoder.aacLc;
        const config = RecordConfig(
          encoder: encoder,
          numChannels: 1,
          sampleRate: 22000,
          bitRate: 64000,
        );

I tried to add sampleRate or bitRate in RecordConfig for aacLc encoder but it make the following crash

[ERROR:flutter/shell/common/shell.cc(1055)] The 'xyz.luan/audioplayers/events/6b7b4f61-3d62-47d8-bb98-3646bf2ece58' channel sent a message from native to Flutter on a non-platform thread. Platform channel messages must be sent on the platform thread. Failure to do so may result in data loss or crashes, and must be fixed in the plugin or application code creating that channel.

To Reproduce

Steps to reproduce the behavior:

1. Go to example
2. In audio_recorder.dart use AudioEncoder.aacLc and add bitRate:64000

Expected behavior

I expected the sampleRate and bitRate to work fine for all encoder types, especially aacLc

I tried amr encoder const encoder = AudioEncoder.amrNb; with
const config = RecordConfig(
encoder: encoder,
numChannels: 1 );

and I got this new error

so

• amrNB didn't work even with the default config
• aaclc didn't work but with custom bitRate
• wav works fine for windows

Ok so for AAC, the message is pretty clear, you can't record with the values you gave.
You can refer to this doc for available values.

And for AMR, I'm not responsible of audio playing.

Thanks a lot for your effort and support
I tried for ACC encoder the following form Wikipedia and it work fine

bitRate: 96000,
sampleRate: 44100

Thanks a lot

recording by amrNb was the best encoder as it is more suitable for speech recording while it has the minimum size for that case
