You can use the PancakeView: https://github.com/sthewissen/Xamarin.Forms.PancakeView

This View supports rounded corner, shadow and gradients (with start and end color, plus gradient angle).

You can have a PancakeView for background (with white background, rounded corner and shadow) and inside a StackLayout (or Grid) with two Label "Existing user" and "New user". Every Label with a GestureRecognizer so when is tapped you can display another PancakeView with gradient background between the Label and the PancakeView in background.

You have to embed everything in a Grid so you can display layers on top eachoter. It could be tricky to micromanage but it is doable without too much effort.
