how to change the icon when have no children in flutter widget?-CodePudding

IconButton(
            onPressed: () {
              Navigator.pushNamed(context, Routes.notification);
            },
            icon: ImageIcon(
              Notification == null ? AssetImage("../../images/Icons/bell.png")  : AssetImage("../../images/Icons/bin.png"),
              size: 21,
            ),
          ),

What i wanted is to change the icon whenever any specific widget contains 0 children

My Idea is to change the notification icon when we have zero notification and use another icon when notification widget have same children or have some notification

Check out this flutter package

now just add items to your List in StatefulWidget by setState and do what you like, if you need IconButton just pass it in child of your Badge,

read badges doc to fix badgeContent, good luck
