Description
Steps to Reproduce
I have a build function like this:
Widget build(BuildContext context) {
return new Scaffold(
key: _key,
appBar: new AppBar(title: new Text(appBarTitle)),
body: new ListView(
children: [
_thingOne(),
_thingTwo(),
new Container(
padding: new EdgeInsets.symmetric(
vertical: style.wideMargin, horizontal: style.defaultMargin),
child: new Card(
child: new ListView(
itemExtent: kListItemExtent[MaterialListType.oneLine],
children: _subItems,
shrinkWrap: true,
),),),],),);
}
When the ItemExtent is set, I get a render error. It also happens if I set it to some literal double (rather than using kListItemExtent) and it doesn't happen if I use itemExtent on the outer ListView. Maybe this is just something I'm not understanding about what itemExtent is meant to do, but wanted to let you know.
Logs
