title: Android Bottom Sheet smooth expanding, like Google Maps
body: <p>I want to recreate Bottom Sheet Behavior provided in the Google Maps app:
  <br><br>
  <a href="https://media.giphy.com/media/1syNHM25tZ1Sw/giphy.gif" rel="noreferrer">Link to expected behavior.</a>
  <br><br>
  I have tried using <a href="https://developer.android.com/reference/android/support/design/widget/BottomSheetBehavior.html" rel="noreferrer">BottomSheetBehavior</a> and couple of other 3rd party libs like umano AndroidSlidingUpPanel but the problem I was unable to avoid is they are all snapping the Bottom Sheet in between states (collapsed and expanded).
  <br><br>
  I would like to have a Bottom Sheet which can be smoothly expanded by sliding up, without it snapping to the closest state but instead to remain where the user stopped with the sliding.</p>
