CheckboxListTile class

A ListTile with a Checkbox. In other words, a checkbox with a label.

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

The value, onChanged, and activeColor properties of this widget are identical to the similarly-named properties on the Checkbox 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 checkbox is checked, pass the same value to both.

The checkbox is shown on the right by default in left-to-right languages (i.e. the trailing edge). This can be changed using controlAffinity. The secondary widget is placed on the opposite side. This maps to the ListTile.leading and ListTile.trailing properties of ListTile.

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

This widget shows a checkbox that, when checked, slows down all animations (including the animation of the checkbox itself getting checked!).

This sample requires that you also import 'package:flutter/scheduler.dart', so that you can reference timeDilation. 

CheckboxListTile(
  title: const Text('Animate Slowly'),
  value: timeDilation != 1.0,
  onChanged: (bool value) {
    setState(() { timeDilation = value ? 20.0 : 1.0; });
  },
  secondary: const Icon(Icons.hourglass_empty),
)
