Flutter - ListView not showing - flutter-web

Question

For some reason the ListView isn't showing up. I think that the height of one of widgets is getting a non-height from its parent... maybe? It seems that there are widgets that don't auto-size with its contents. I don't want to force a size for any of the containers because they could contain different amounts of information. https://codepen.io/dhust/pen/vYGZLPZ
Update:
Error: Cannot hit test a render box with no size. The hitTest() method was called on this RenderBox:
class MyWidget extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Padding(
padding: const EdgeInsets.all(16.0),
child: Container(
child: Column(
children: [
Row(
children: [
Container(
child: Column(
children: [
Expanded(
child: ListView.builder(
itemCount: 4,
itemBuilder: (BuildContext context, int index) {
return Text("Hi");
},
),
),
],
),
),
],
),
],
),
),
),
);
}
}

Answer 1

For ListView add shrinkWrap: true, to avoid "Vertical viewport was given unbounded height." error and Use Expanded for its parent Column to avoid "constraints.hasBoundedWidth is not true".
Column(
children: [
Row(
children: [
Expanded( // Use Expanded here
child: Container(
child: Column(
children: [
ListView.builder(
shrinkWrap: true, // and use shrinkWrap
itemCount: 4,
itemBuilder: (BuildContext context, int index) {
return Text("Hi");
},
),
],
),
),
),
],
),
],
),
result:
