SwitchListTile constructor
Creates a combination of a list tile and a switch.
The switch tile 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 tile with a new value
to update the visual
appearance of the switch.
The following arguments are required:
value
determines whether this switch is on or off.onChanged
is called when the user toggles the switch on or off.
Implementation
const SwitchListTile({
Key key,
@required this.value,
@required this.onChanged,
this.activeColor,
this.activeTrackColor,
this.inactiveThumbColor,
this.inactiveTrackColor,
this.activeThumbImage,
this.inactiveThumbImage,
this.title,
this.subtitle,
this.isThreeLine = false,
this.dense,
this.secondary,
this.selected = false,
}) : _switchListTileType = _SwitchListTileType.material,
assert(value != null),
assert(isThreeLine != null),
assert(!isThreeLine || subtitle != null),
assert(selected != null),
super(key: key);
