title: Xamarin forms 4 shell navigation with complex parameters
body: <p>I´m migratting a xamarin forms 3.x app with Prism to forms 4 with shell navigation.</p>
  
  <p>Do I have to create my custom solution to pass complex parameters to the new page or Xamarin has some buildin feature to receive other than string parameters?</p>
  
  <p>Thanks.</p>
