Error: Getter not found: 'widget'. widget.icon

Question

I am creating a card component that contains icons and text as a children's widget. I initialize these icons and wanted to make use of them inside its children widget but it's giving errors

The error is indicated above the image. It happened on widget.icon, widget.title, and it's also happened if I used it on widget.subtitle. Below is the full code

import 'package:flutter/rendering.dart';
import 'package:font_awesome_flutter/font_awesome_flutter.dart';
import 'package:api_example_app/constants.dart';
import 'package:flutter/widgets.dart';

class CardsParent extends StatefulWidget {
 const CardsParent({
   Key key,
   @required this.size,
   this.icon,
   this.title,
   this.subtitle,
 }) : super(key: key);

 final Size size;
 final IconData icon;
 final String title;
 final String subtitle;

 @override
 _CardsParentState createState() => _CardsParentState();
}

class _CardsParentState extends State<CardsParent> {
 @override
 Widget build(BuildContext context) {
   return Container(
     width: 140,
     height: 100,
     child: Card(
       shape: RoundedRectangleBorder(
         borderRadius: BorderRadius.circular(15.0),
       ),
       color: Colors.white,
       elevation: 10,
       child: Column(
         mainAxisSize: MainAxisSize.min,
         children: <Widget>[
           const ListTile(
             leading: Icon(
               widget.icon,
               size: 50,
               color: kOrangeColor,
             ),
             title: Text('Temp',
                 style: TextStyle(fontSize: 18.0, color: kOrangeColor)),
             subtitle: Text('33C', style: TextStyle(color: kOrangeColor)),
           ),
         ],
       ),
     ),
   );
 }
}

Am I doing something wrongly?

You've to remove the const from your ListTile.
