title: OnAppearing check from which Page the User is comming in Xamarin.forms
body: <p>Is there a way i can detect, from which page the user is coming inside of the OnAppearing event in a ContentPage? As well as by pushing a Page to the Navigation or poping it.</p>
  
  <p>I'm trying to do something like this.</p>
  
  <pre><code>protected override void OnAppearing()
  {
      base.OnAppearing();
      if(/*User comes from certain page*/){
          //Do stuff
      }else{
          //Do other stuff
      }
  }
  </code></pre>
