title: What is the easiest way to rotate an image in Xamarin Forms using MVVM with Prism
body: <p>what is the easiest way to for example rotate an image by 180 degrees when clicking the image with a command from the ViewModel? I am using Prism.</p>
  
  <p>Since there is also some Logic behind the click, I've tried mixing it up with a Gesture Regognizer and an event handler, but that does not work well together.</p>
