class Parent extends StatelessWidget {
const Parent({super.key});

@override
Widget build(BuildContext context) {
return BoxBuilder(builder: (context, constraints, build, order) {
final a = build(const SizedBox(height: 200, width: 100));
final b = build(const SizedBox(height: 200, width: 100));

a.layout(constraints);
b.layout(constraints);

b.offset = Offset(0, a.size.height);

return Size(max(a.size.width, b.size.width), a.size.height + b.size.height);
});
}
}

Would place box b under box a.
