Flutter Network Image does not fit in Circular Avatar : <p>I am trying to retrieve bunch of images from an api. I want the images to be displayed in Circular form so I am using <code>CircleAvatar</code> Widget, but I keep getting images in square format.
 Here is a screenshot of images</p>

<p>Here is the code I am using</p>

<pre><code>ListTile(leading: CircleAvatar(child: Image.network("${snapshot.data.hitsList[index].previewUrl}",fit: BoxFit.scaleDown,)),),
</code></pre>

<p>I tryied using all the properties of <code>BoxFit</code> like <code>cover</code>, <code>contain</code>,<code>fitWidth</code>,<code>fitHeight</code> etc but none of them works.</p>
