recorder_onProgress isn't same as on picture

Basically if you try to make same code as recorder_onProgress.dart has, you will not have same result as in shown picture to code https://github.com/Canardoux/flutter_sound/blob/master/flutter_sound/example/lib/recorder_onProgress/recorder_onProgress.png

as you see, we don't have play function there, only record

should I implement it by my own? if yes, please give me a link if there is any example
or it's just me and I don't understand something 🤯

Sorry, I just figured out that the main purpose here was to show how to change subscription duration, accidently thought it was for representing slider for scrolling audio player
