A minor modified version from @yiky84119 to avoid breaking original behavior:

Widget build(BuildContext context) {
    return GetMaterialApp(
      scrollBehavior: MyCustomScrollBehavior()
}

class MyCustomScrollBehavior extends MaterialScrollBehavior {
  @override
  Set<PointerDeviceKind> get dragDevices => {
    ...super.dragDevices,
    PointerDeviceKind.mouse,
  };
}

By the way, the comments of dragDevices says:

  /// The device kinds that the scrollable will accept drag gestures from.
  ///
  /// By default only [PointerDeviceKind.touch], [PointerDeviceKind.stylus], and
  /// [PointerDeviceKind.invertedStylus] are configured to create drag gestures.
  /// Enabling this for [PointerDeviceKind.mouse] will make it difficult or
  /// impossible to select text in scrollable containers and is not recommended.

So mouse may not be the suggested approach.

Pull up and pull down both not working on the M1 Mac chrome browser. Tried adding PointerDeviceKind.trackpad, but no luck. Does anyone know any fix?
