Xamarin.Forms custom control showing a before-and-after view

BeforeAndAfter

A custom control that displays a before-and-after view of something. You usually provide two images and overlap them.

Get it from NuGet:

Here's a quick rundown of the control's features:

• Specify the before and after views. These can be whatever Xamarin.Forms views you want, in the sample I'm using two normal Image controls.
• OPTIONAL: provide your own thumb control. Have a look at the sample, I'm using a material design icon.

Known Limitations

On iOS you might have jittery movement. Just add thesetwo lines to your App.xaml

         xmlns:ios="clr-namespace:Xamarin.Forms.PlatformConfiguration.iOSSpecific;assembly=Xamarin.Forms.Core"
         ios:Application.HandleControlUpdatesOnMainThread="true"

Here's a gif of the included sample app:

As usual you can do everything you want with my code. Have fun!
