title: Dynamic height of listview builder item
body: <p>I am unable to set the dynamic size to my list item of list view builder, every time it shows blank screen and when I specify a constant size it works.</p>
  
  <p>I tried by using column by setting <code>mainAxisSize=minimum</code> and by using container as we know container wraps the child height but nothing works</p>
  
  <pre><code> listItem (GuideLines news) =&gt;Column(
      mainAxisAlignment: MainAxisAlignment.start,
      mainAxisSize:  MainAxisSize.min,
      children: &lt;Widget&gt;[Container(

          "${news.featured_image}",

          cacheRule: CacheRule(maxAge: const Duration(days: 7)),
        ),fit: BoxFit.cover)),
        margin: EdgeInsets.only(bottom: 10.0),
        child: ListTile(
          onTap: (){
            print(news.web_link);
            Navigator.push(context, MaterialPageRoute(builder: (context) =&gt; NewsDetailsPage(news)));
          },
