SwitchListTile class

A ListTile with a Switch. In other words, a switch with a label.

The entire list tile is interactive: tapping anywhere in the tile toggles the switch.

The value, onChanged, activeColor, activeThumbImage, and inactiveThumbImage properties of this widget are identical to the similarly-named properties on the Switch widget.

The title, subtitle, isThreeLine, and dense properties are like those of the same name on ListTile.

The selected property on this widget is similar to the ListTile.selected property, but the color used is that described by activeColor, if any, defaulting to the accent color of the current Theme. No effort is made to coordinate the selected state and the value state; to have the list tile appear selected when the switch is on, pass the same value to both.

The switch is shown on the right by default in left-to-right languages (i.e. in the ListTile.trailing slot). The secondary widget is placed in the ListTile.leading slot. This cannot be changed; there is not sufficient space in a ListTile's ListTile.leading slot for a Switch.

To show the SwitchListTile as disabled, pass null as the onChanged callback.

This widget shows a switch that, when toggled, changes the state of a bool member field called _lights.
SwitchListTile(
  title: const Text('Lights'),
  value: _lights,
  onChanged: (bool value) { setState(() { _lights = value; }); },
  secondary: const Icon(Icons.lightbulb_outline),
)
