title: Circle/wheel ScrollView in Flutter
body: <p>I'm having a hard time finding a widget I need in Flutter, which I thought wouldn't be that rare.
  What I'm looking fore is something very similar to this:</p>
  <p><a href="https://i.stack.imgur.com/gKxjf.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/gKxjf.gif" alt="enter image description here" /></a></p>
  <p>Which is available at <a href="https://pub.dev/packages/circle_wheel_scroll" rel="nofollow noreferrer">pub.dev</a>, but doesn't have the flexibility I'm looking for.</p>
  <p>Ideally, the widget I'm looking for wouldn't end like this one (when you keep scrolling it would go back to the first element). Also, I intend on stacking concentric wheel ScrollViews with different diameters.</p>
