Basically, user can drag the bottomsheet even when item 0 is listed which means the _drag is not null when user tries to perform drag. Hence, the assert _drag == null line was throwing error. I just removed that line and confirmed that dragging the bottomsheet opens the listview properly without throwing any errors in the console.
