How to add multiple children to flutter body - flutter

Question

Good day, I need help adding a second child to the body of my screen. I keep on getting the error "The argument for the named parameter 'children' was already specified." If I take that piece of code out, my 'app' works perfectly. I've tried adding Column to my body (saw it in a different question) but it still gives me the error.
The problematic code is
,children: [TextButton(
onPressed: () {
Navigator.push(context, MaterialPageRoute(builder: (context) {
return const FeatureScreenDos(title: 'Feature Screen dos');
Full Code:
class DashBoard extends StatelessWidget {
const DashBoard({Key? key, required this.title}) : super(key: key);
final String title;
#override
Widget build(BuildContext context){
return Scaffold(
appBar: AppBar(
title: Text(title),
),
body: Column(
children: [TextButton(
onPressed: () {
Navigator.push(context, MaterialPageRoute(builder: (context) {
return const FeatureScreenUno(title: 'Feature Screen uno');
}));
},
child: const Text('Feature Screen uno')
)
]
,children: [TextButton(
onPressed: () {
Navigator.push(context, MaterialPageRoute(builder: (context) {
return const FeatureScreenDos(title: 'Feature Screen dos');
}));
}
,child: const Text('Feature Screen dos'),
),
]
)
);
}
}`

Answer 1

adding multiple children to Column or Row or any other multi child widget is not like that,
you would have a single Column with a list of children inside it
Column(
children: [
const Text('Child 1'),
const Text('Child 2'),
...
]
)
please refer to Column widget to know more about column, same work goes to row & some other multi child widgets

Answer 2

class DashBoard extends StatelessWidget {
const DashBoard({Key? key, required this.title}) : super(key: key);
final String title;
#override
Widget build(BuildContext context){
return Scaffold(
appBar: AppBar(
title: Text(title),
),
body: Column(
children: [
///child one
TextButton(
onPressed: () {
Navigator.push(context, MaterialPageRoute(builder: (context) {
return const FeatureScreenUno(title: 'Feature Screen uno');
}));
},
child: const Text('Feature Screen uno')
),
///child two
TextButton(
onPressed: () {
Navigator.push(context, MaterialPageRoute(builder: (context) {
return const FeatureScreenDos(title: 'Feature Screen dos');
}));
}
,child: const Text('Feature Screen dos'),
),
]
)
);
}
}`
body will always take one child we customize further ourselfs by adding column and rows for example here you can add a row as well in children if you want to show something horizontal after text buttons and further add more children to rows
