A colleague found this:

And according to DyaryRaoof the solution is:
I am on the master branch. This error appears in iOS.To solve it you need to locate your audio_recorder plugin inside flutter. then change the name of it's last child folder on android. You have to change it from audio_recorder to audiorecorder(remove the underscore).
Or just wait for the package maintainer to solve that issue.
