How to add multiple rows or columns after the body - flutter

Question

I'm still trying to understand how to structure widgets. I have placed a container in the body already so how can I now add another row. I've removed some code to simplify my situation but hopefully this gives an idea of how my project is structured at the moment.
class AddButton extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
alignment: Alignment.bottomCenter,
//Stats Button
child: Row(
), //container
//How can I enter a new row here <------- WHERE I WANT TO ENTER A ROW
);
}
}

The short answer is, you cannot. You can take advantage of the children property of a Column, the most common layout widget in all of Flutter. Flutter works on a system of nested widgets, you cannot have many parents as it all starts with one widget.
class AddButton extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
alignment: Alignment.bottomCenter,
//Stats Button
child: Column(
children: <Widget>[
Row(
children: <Widget>[
// nested widgets
],
),
],
),
),
);
}
}
Judging by your class name, you just want a button. Not every widget starts with a Scaffold, that's only if you want an entire layout with an app bar or a bottom navigation bar. For simple widgets like a button, you can get rid of Scaffold entirely and just use MaterialButton like this.
class AddButton extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialButton(
onPressed: () {}, //empty function
);
}
}
