title: NativeScript + Angular Navigation context
body: <p>i'm trying to navigate between a list to a details page. Since i've already fetched everything in my list component i'd like to pass the JSON to the details page so that i've already everything I need to render the component.</p>
  
  <p>I tried many things</p>
  
  <pre><code>this._router.navigate(['details', JSON.stringify(item)]) // seems to truncate the JSON
  this._router.navigate(['details', item]) // raises an  Cannot match any routes
  </code></pre>
  
  <p>Then i tried to remove the <code>:item</code> url parameter from the route definition 
  and was trying to use the <code>queryParams</code> parameter which is allowed but i'm unable to read it in the DetailsPage.</p>
