vertical property
If true, rotates the Slider by 90 degrees. Keeps the orientation of the TextField and the leading widget. Default is false.
Note: This puts all widgets (Slider, TextField and leading widget) inside a Column instead of a row. When using this InputSlider inside another Column, you have to constrain the height of this InputSlider by using widgets such as SizedBox, Expanded or Flexible.
Implementation
final bool vertical;
