@override
Widget build(BuildContext context) {
final carbsProvider = Provider.of<CarbsProvider>(context);
var mycarb = 1;

Column(

for (var i = 0; i < carbsProvider.carbs.length; i++)
RadioListTile(
title: Text(carbsProvider.carbs[i].name),
value: i,
onChanged: (var v) {
print("object");
mycarb = v;
},
groupValue: mycarb,
)
],
),
// for (var i = 0; i < widget.custom.fooditems.length; i++)
// Text(
// widget.custom.fooditems[i],
// style: TextStyle(fontSize: 30.0, fontWeight: FontWeight.bold),

));
}
}
Wrap your onChanged in setState. just like
