Xamarin Forms Drag and Drop on Button controls

Hi all,

I am busy porting my android code to forms. I currently have buttons in android that are dragable. Using the Button control from Xamarin Forms there is no obvious way of doing this. With the android button widget there is a Drag event, but there does not seem to be a similar event for a forms button.

Any help to point me in the right direction here would be greatly appreciated!

Thanks
