title: Make current screen into BLUR on Xamarin.forms
body: <p>I'm making app with using Xamarin.forms PCL project.
  I just wanted to know if there is some way to make current screen into blur screen. 
  I will put something on it.</p>
  
  <p>I'm using SkiaSharp 2d library for XF which works great and support blur image. 
  But it's for image file to make blur. </p>
  
  <p>Should I take a screenshot for current screen and put it on the top and make it blur?</p>
  
  <p>Any tip will be helpful.</p>
  
  <p>Thanks.</p>
