I have a DropdownButton (entries of type String) and an IconButton in a Row widget. Each time an entry from the DropdownButton is selected and the IconButton is tapped, an InputChip with the selected entry as its child should be created in a Row widget below the initial Row. How can this be done?
class _MyHomePageState extends State<MyHomePage> {
List<String> templist = new List();
@override
Widget build(BuildContext context) {
SizeConfig().init(context);
return Scaffold(
body: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Wrap(
children: templist
.map(
(f) => Chip(
label: Text(f),
deleteIcon: CircleAvatar(
minRadius: 10.0,
child: Icon(
Icons.clear,
color: Colors.white,
size: 20,
),
),
deleteIconColor: Colors.red,
onDeleted: () {
setState(() {
templist.remove(f);
});
},
),
)
.toList(),
),
new DropdownButton<String>(
isExpanded: true,
hint: Text("Click here"),
items: <String>['A', 'B', 'C', 'D'].map((String value) {
return new DropdownMenuItem<String>(
value: value,
child: new Text(value),
);
}).toList(),
onChanged: (value) {
setState(() {
templist.add(value);
});
},
)
],
));
}
}
