Wrap <code>ClipOval</code> with <code>Sizebox</code> so that always it have same size and height
<pre><code> SizedBox(
 height: 60,
 width: 60,
 child: ClipOval(
 child: conversation.image=='' ? 
 Image.asset('assets/images/defaultuser.png',fit:BoxFit.cover,):
 Image.network(conversation.image!,fit:BoxFit.cover,),))
 
</code></pre>
This should generate image like this: <a href="https://i.stack.imgur.com/uxq4c.png" rel="nofollow noreferrer">https://i.stack.imgur.com/uxq4c.png</a>

I think your image is rectangular that's why it doesn't fit in <code>CircleAvatar</code>.
Try this
<pre><code> CircleAvatar(
 backgroundColor: Colors.transparent,
 child: ClipOval(
 clipBehavior: Clip.antiAlias,
 child: ImageAssetWidget(
 imagePath: ImageAssets.cardHomeTopBG,
 ),
 ),
 radius: 25,
 ),
</code></pre>

I'm trying to fit the image with my CircleAvatar, I've tried setting the height and width of the image but it didn't work. Tried BoxFit.fill, BoxFit.cover, BoxFit.fitWidth and BoxFit.fitHeight but still didn't work.
Here is the CircleAvatar:
<a href="https://i.stack.imgur.com/3t8om.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3t8om.png" alt="enter image description here" /></a>
And my code:
<pre><code> ClipOval(
 child: conversation.image=='' ? 
 CircleAvatar(child: Image.asset('assets/images/defaultuser.png',),radius: 25,) : 
 CircleAvatar(child: Image.network(conversation.image!),radius: 25,)
 ),
</code></pre>
