Fast scrolling in Xamarin CollectionView

Question

For ListView one can activate fast scrolling by setting android:ListView.IsFastScrollEnabled="True" on it. With this option the scrollbar becomes touchable to scroll through large lists fast. Unfortunately this property does not have an effect on CollectionView. Is there a way to get a similar behavior on it?

As usual everything is possible, but there is no easy way to do this.

ListView in Xamarin.Forms uses ListView on Android which has fast scroll built into the control.

CollectionView in Xamarin.Forms uses RecyclerView and it doesn't have fast scroll built-in.

Overall this means that you can only write a custom renderer starting with Xamarin code from github and apply advice from here: How to add a fast-scroller to the RecyclerView
