How to Force Show BottomAppBar - Xamarin Android

Question

In xamarin Android, I have used the bottomappbar as shown below.I have implemented the hide on scroll behavior of BottomAppBar.Scrolling downward hides the bottom app bar. If a FAB is present, it detaches from the bar and remains on screen.Scrolling upward reveals the bottom app bar, and reattaches to a FAB if one is present.

        </LinearLayout>
    </android.support.design.bottomappbar.BottomAppBar>
</android.support.design.widget.CoordinatorLayout>
       

The bottomappbar hides and shows when I scroll the recyclerview. However I would like to show it when it reaches the bottom of list.How can I force to show the BottomAppBar?
