wrap the NumberPicker with ScrollConfiguration and provide the behavior property. By default Scroll View mouse drag gesture is disabled in Flutter.

https://docs.flutter.dev/release/breaking-changes/default-scroll-behavior-drag

ScrollConfiguration(
  behavior: ScrollConfiguration.of(context).copyWith(dragDevices: {
    // enable touch and mouse gesture
    PointerDeviceKind.touch,
    PointerDeviceKind.mouse,
  }),
  child: NumberPicker(),
);

The StateFulBuilder seems to fix the issue!
