dragDevices property

@override Set<PointerDeviceKind> get dragDevices

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.

Implementation

@override
Set<PointerDeviceKind> get dragDevices => {
      PointerDeviceKind.touch,
      if (allowMouseDragging) PointerDeviceKind.mouse,
      PointerDeviceKind.stylus,
      PointerDeviceKind.invertedStylus,
      PointerDeviceKind.trackpad,
      PointerDeviceKind.unknown,
    };
