xaml - C# custom control (circle progress bar) Xamarin Forms

I want to know the best way to create the similar thing of this image with Xamarin Forms:

I never created anything like that. I know how to use Progress bar, but not a 'circle progress bar'

Thank you for your help and for any tips.

EDIT : If you have a plugin/nuget to do that, it's cool, but I would like to know how to do it myself. I never made something like this.
