acc audio file does not work with on seek using just audio

Question

I am building a music Flutter app with using just_audio plugin I have a list of acc audio files from server, but I noticed that onSeek method does not work correctly with acc file.

I tried too many difference format they were all working as well with onSeek method except acc file format.

The behavior I got is it return always the duration to zero in every time I animate the slider.
