Creates a vertical SfSlider.

TooltipPosition

Enables tooltip in left or right position for vertical slider.

Defaults to SliderTooltipPosition.left.

Example

This snippet shows how to create a vertical SfSlider with right side tooltip.

double _value = 4.0;

@override
Widget build(BuildContext context) {
  return MaterialApp(
     home: Scaffold(
         body: Center(
             child: SfSlider.vertical(
                    min: 0.0,
                    max: 10.0,
                    value: _value,
                    enableTooltip: true,
                    tooltipPosition: SliderTooltipPosition.right,
                    onChanged: (dynamic newValue) {
                        setState(() {
                            _value = newValue;
                        });
                  },
             )
          )
      )
  );
}
