Check if item is empty then show Icon button or nothing in flutter

Question

I have checked other questions but I have not seen anything which helps me understand what I need to achieve, I have a json file which populates the ListTile, but I do not want to have the IconButton show if the skills display is empty. My code does what I want it to do but it displays icons on every tile and I only want it to display if it has a link.

Please help as I know this is an easy fix and I cannot get my head around it. Thank you

   return ListTile(
       leading: CircleAvatar(child: Text(skill.skill_id)),
          title: Text(skill.skill_name),
          subtitle: Text(skill.skill_type),
            trailing:IconButton(
             onPressed: () {
               if(skill.skill_disp.isNotEmpty)
              launchUrl(Uri.parse(skill.skill_disp));
            },
            icon: Icon(CupertinoIcons.videocam_circle),
          ),
        );

This would do what you described:

   return ListTile(
       leading: CircleAvatar(child: Text(skill.skill_id)),
          title: Text(skill.skill_name),
          subtitle: Text(skill.skill_type),
            trailing:skill.skill_disp.isNotEmpty?IconButton(
             onPressed: () {
               if(skill.skill_disp.isNotEmpty)
              launchUrl(Uri.parse(skill.skill_disp));
            },
            icon: Icon(CupertinoIcons.videocam_circle),
          ):Container(),
        );
