title: Xamarin Forms FFImageLoading Image not showing
body: <p>I am trying to use <code>FFImageLoading</code> in one of our Xamarin Forms Projects but I am having some weird issues.</p>
  
  <p>When I try to put <code>Sources="anyvalidimageurl"</code> on the XAML, I get this error:</p>
  
  <blockquote>
    <p>Invalid XAML: Value cannot be null. Parameter name: 'obj'</p>
  </blockquote>
  
  <p>This is the XAML:</p>
  
  <pre><code>&lt;ffimageloading:CachedImage HorizontalOptions="Center" 
              WidthRequest="300" 
              HeightRequest="300"
              DownsampleToViewSize="true"
              Source="http://myimage.com/image.png"
              x:Name="imgImage"&gt;
  &lt;/ffimageloading:CachedImage&gt;
  </code></pre>
  
  <p>I tried to load the image through code, but no image is shown on iOS.</p>
