Listview with radio buttons in flutter slows performance - flutter

Question

I would like to update when the value of radio button changes in flutter But its slowing down the app.
I have created the following listview with the radio buttons yes and no
final List<ItemModel> _questions =
List.generate(100, (index) => ItemModel(name: 'nm_$index', id: index + 1, checked: ''));
ListTile(
title: Text((index + 1).toString() + ". " + question.name),
subtitle: Column(
children: [
ListTile(
onTap: () {
setState(() {
_questions[index].checked = 'yes';
});
},
title: const Text("Yes"),
leading: Radio(
value: 'yes',
groupValue: question.checked,
onChanged: (val) {
setState(() {
_questions[index].checked = 'yes';
});
}),
),
ListTile(
title: const Text("No"),
onTap: () {
setState(() {
_questions[index].checked = 'no';
});
},
leading: Radio(
value: 'no',
groupValue: question.checked,
onChanged: (val) {
setState(() {
_questions[index].checked = 'no';
});
}),
)
],
));
The above listview has two radio buttons where each row is either marked as yes or no. It works well for a small list but when the list gets larger like the above with 100 items the app starts to slow down. I believe its caused by the calling of setState on each radio button click which then causes the ui to be rebuilt.
Is there a way i can update the status of the selected radio without causing the ui to rebuild or is there a way i can improve the above to make the app stop lagging and slowing down when there is alot of items.
