How to detect Left swipe and Right swipe for Stacklayout in Xamarin.Forms?

I have been trying to detect left swipe and right swipe for stacklayout. Things in which I need help are,

1. Creating a stacklayout renderer to add swipe Gesture.
2. How to detect user has swiped left or right.

Please provide a solution which works on cross platforms.

Providing an example for stacklayout renderer will be really helpful to acheive the swipe functionality in xamarin.forms
