Flutter UI doesn't update with changes on StateNotifier - flutter

Question

I want to create a list o buttons with text so that the user can select one of them.
For the state of the buttons I used a StateNotifier:
class SeleccionStateNotifier extends StateNotifier<List<bool>> {
int cantidad;
SeleccionStateNotifier(this.cantidad)
: super(List.generate(cantidad, (index) => false));
void CambioValor(int indice) {
for (int i = 0; i < cantidad; i++) {
if (i == indice) {
state[i] = true;
} else {
state[i] = false;
}
}
}
}
final seleccionProvider =
StateNotifierProvider<SeleccionStateNotifier, List<bool>>((ref) {
final lector = ref.watch(eleccionesSinSeleccionStateNotifierProvider);
return SeleccionStateNotifier(lector.length);
});
Now in the UI I just want to show a text and the value of the button (false for everyone except the one the user selects)
class EleccionesList5 extends ConsumerWidget {
const EleccionesList5({Key? key}) : super(key: key);
#override
Widget build(BuildContext context, ScopedReader watch) {
bool este = false;
final eleccioneswatchCon =
watch(eleccionesSinSeleccionStateNotifierProvider);
final seleccionwatch = watch(seleccionProvider);
final buttons = List<Widget>.generate(
eleccioneswatchCon.length,
(i) => Container(
padding: const EdgeInsets.fromLTRB(5, 2, 5, 2),
child: TextButton(
onPressed: () {
context.read(seleccionProvider.notifier).CambioValor(i);
print('OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO');
for (int id = 0; id < eleccioneswatchCon.length; id++) {
print(seleccionwatch[id]);
}
},
child: Text(eleccioneswatchCon[i].eleccion + ' ' + seleccionwatch[i].toString()),
),
),
).toList();
return Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: [
Wrap(
alignment: WrapAlignment.spaceAround,
children: buttons,
),
],
);
}
}

Answer 1

based on my previous answer you should update state itself, not an inner value of a list to take effect
void CambioValor(int indice) {
final list = List.of(state);
for (int i = 0; i < cantidad; i++) {
if (i == indice) {
list[i] = true;
} else {
list[i] = false;
}
}
/// it will update when you use the setter of state
state = list;
}
