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.

Properties

autofocus → bool
True if this widget will be selected as the initial focus when no other node in its scope is currently focused.
final
checked → bool
Getter used to link T to a bool value. If true, the YaruTogglable will be considered as checked.
no setter
focusNode → FocusNode?
An optional focus node to use as the focus node for this widget.
final
hashCode → int
The hash code for this object.
no setterinherited
interactive → bool
Determine if this YaruTogglable can handle events.
no setter
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
mouseCursor → MouseCursor?
The cursor for a mouse pointer when it enters or is hovering over the widget.
final
onChanged → ValueChanged<bool>?
Called when the user toggles the switch on or off.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
selectedColor → Color?
The color to use when this switch is on.
final
statesController → WidgetStatesController?
Controls the states of the YaruTogglable.
final
thumbColor → Color?
The color to use for the thumb when this switch is on.
final
tristate → bool
By default, a YaruTogglable widget can only handle two state. If true, it will be able to display tree values.

value → bool
