If you want to use setState then you should use StatefulWidget instead of a StatelessWidget, I am assuming you are trying to setState on a stateless widget.
Below is the example to explain you how to use setState with stateful widget:
class HomePage extends StatefulWidget {
const HomePage({Key? key}) : super(key: key);
@override
State<HomePage> createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
int incrementValue = 0;
@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
body: InkWell(
onTap: () {
setState(() {
//write code here
incrementValue++;
});
},
child: Text("Press Here $incrementValue"),
));
}
}
