Draw a rounded rectangle border with cutout in Xamarin.Forms

Issue

I need to a rounded border in Xamarin.Forms, as i need to customize the thickness i can't go with existing Frame class.

Constraints

• Green background is not permanent value, it can be changed dynamically.
• Gap width is also dynamic one.
• Able to change corner radius, thickness and color of the border.

I came across some class in Java for similar implementation CutoutDrawable

Without using SkiaSharp in Xamarin.Forms, kindly do share your suggestion to achieve this in custom renderers.

Solution

Porter-Duff mode is option available to achieve my requirement. Each platforms contains its own API for this approach.
