My output
How to align horizontally this Icon , Text and radio button.Radio button and text display nicely but Icon and text are not align horizontally. How make this?
my code
ListTile( leading: Icon( Icons.brightness_1, color: Colors.black, size: 13, ), minLeadingWidth: 2, title: Text("Can you understand?"), trailing: Radio( value: "talk", groupValue: level, onChanged: (value) { setState(() { level = value.toString(); }); }, ), ), 
Try this:
ListTile( leading: Column( mainAxisAlignment: MainAxisAlignment.center, crossAxisAlignment: CrossAxisAlignment.center, children: [ Icon( Icons.brightness_1, color: Colors.black, size: 13, ), ], ), minLeadingWidth: 2, title: Text("Can you understand?"), trailing: Radio( value: "talk", groupValue: "level", onChanged: (value) { }, ), ), You can try this for leading:
leading: Container( height: 24, width: 24, alignment: Alignment.center, child: Icon( Icons.brightness_1, color: Colors.black, size: 13, ), ),
