How do I use variables in a list? - flutter - list

Question

im pretty new to flutter, tried for a while on my own now, but didnt find a solution online or within my own skills.
The problem:
list<Widget>sport = [sport1(name: name1)];
name is the variable I use in the child widget ( a callback if I remember right).
name1is the variable in the parent.
Now I want name to be changed, when I change name1
The problem is, I cant use name1 in list. I cant use any variable in list.
Error: Can't access 'this' in a field initializer to read 'name1'
I dont have any other acces to my child widget sport1 than in the list.
Code:
void main() {
runApp(MyApp());
}
class MyApp extends StatefulWidget {
#override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
List<Widget> sport = [sport1(name: name1),];
String name1 = 'Max';
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Container(
child: Scaffold(
body: Center(child: sport[0]),),
),
);
}
}
class sport1 extends StatelessWidget {
String name;
sport1({Key key, this.name}) : super(key: key);
#override
Widget build(BuildContext context) {
return Container(
child: Text('$name does x pushups!'),
);
}
}```
