YaruSwitch class

A Yaru switch.

Used to toggle the on/off state of a single setting.

The switch itself does not maintain any state. Instead, when the state of the switch changes, the widget calls the onChanged callback. Most widgets that use a switch will listen for the onChanged callback and rebuild the switch with a new value to update the visual appearance of the switch.

If the onChanged callback is null, then the switch will be disabled (it will not respond to input). A disabled switch's thumb and track are rendered in shades of grey by default. The default appearance of a disabled switch can be overridden with inactiveThumbColor and inactiveTrackColor.

  • YaruSwitchButton, a desktop style switch button with an interactive label.
  • YaruCheckbox, another widget with similar semantics.
  • YaruRadio, for selecting among a set of explicit values.
  • Slider, for selecting a value in a range.
