If you want the item to update automatically, without clicking submit, use this:
class _AddCashFormState extends State<AddCashForm> {
final selectedDate = DateTime.now();
final chipList = <String>[
'one',
'two',
'three',
'four',
];
String item;
@override
Widget build(BuildContext context) {
return Scaffold(
body: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Row(
children: chipList
.map<Widget>((s) => ChoiceChip(
label: Text(s),
selected: s == item,
onSelected: (bool selected) {
setState(() {
item = selected ? s : null;
});
},
))
.toList(),
),
Text(item ?? ''),
],
),
);
}
}
You want to wrap your card in Column because inner Column take full height
Column(children: <Widget>[
Card(
margin: const EdgeInsets.all(10.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
AspectRatio(
aspectRatio: 18.0 / 13.0,
child: Image.network(
"https://i.stack.imgur.com/mDkkT.png",
fit: BoxFit.fill,
),
),
Padding(
padding: EdgeInsets.fromLTRB(16.0, 12.0, 16.0, 8.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
"Demo",
textAlign: TextAlign.center,
),
],
),
),
],
),
)
])
