Flutter: Dart Unhandled Exception: type 'int' is not a subtype of type 'ValueNotifier<int>' of 'function result',

Hi can anyone please tell me what is wrong with this code. I'm trying to create a countdown timer in my widget,

class _SaleSuccessDialogState extends State<SaleSuccessDialog> {
  final ValueNotifier<int> counter = ValueNotifier(10);
  Timer? countDownTimer;

  @override
  void initState() {
    super.initState();
    if (App.preferences.kTillLockAfterSale) {
      Timer.periodic(const Duration(seconds: 1), (timer) {
        countDownTimer ??= timer;
        setState(() => counter.value--);
        if (counter.value == 0) {
          timer.cancel();
        }
      });
    }
  }

ValueListenableBuilder(
  valueListenable: counter,
  builder: (context, counterValue, child) {
    return Text("Counter:$counterValue");
  },
),

This is the error that I'm getting:

Dart Unhandled Exception: type 'int' is not a subtype of type 'ValueNotifier' of 'function result'
