title: How to link linear progress indicator and slider in flutter?
body: <p>I am making a music player where the progress indicator will act as a slider to change the music position and also as a progress bar.<br><br> As far as I understood the slider can only be set manually whereas the linearprogess indicator has no such slider.<br> I want a way to integrate both such that the slider shows the current progress of the music track as well as the user can drag it to affect the value.</p>
  
  <p>Is there any way to do so? Or if I have any misconception please correct me.</p>
  
  <p>THANK YOU</p>
