title: Animate Arrow button while swiping bottomSheet
body: <p>I got a bottomsheet upon which, while swiping i need to animate arrow button indicating weather user swiping up or down?<a href="https://i.stack.imgur.com/MWj2P.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/MWj2P.png" alt="enter image description here"></a></p>
  
  <p>Here is my Sample Test one, while swiping the bottom sheet as you can see in the image, the arrow button at the bottom should rotate downward while swiping up, and on swiping down button should rotate upwards.</p>
  
  <p>Thanks,
