ComCheckboxListTile constructor

const ComCheckboxListTile({ Key? key, required bool? value, required ValueChanged<bool?>? onChanged, MouseCursor? mouseCursor, Color? activeColor, WidgetStateProperty<Color?>? fillColor, Color? checkColor, Color? hoverColor, WidgetStateProperty<Color?>? overlayColor, double? splashRadius, MaterialTapTargetSize? materialTapTargetSize, VisualDensity? visualDensity = const VisualDensity(horizontal: -4.0, vertical: -4.0), Offset offset = const Offset(1, 1), FocusNode? focusNode, bool autofocus = false, ShapeBorder? shape, BorderSide? side, bool isError = false, bool? enabled, Color? tileColor, Widget? title, Widget? subtitle, bool isThreeLine = false, bool? dense, Widget? secondary, bool selected = false, ListTileControlAffinity controlAffinity = ListTileControlAffinity.platform, EdgeInsetsGeometry? contentPadding, bool tristate = false, OutlinedBorder? checkboxShape, Color? selectedTileColor, ValueChanged<bool>? onFocusChange, bool? enableFeedback, String? checkboxSemanticLabel, })

Creates a combination of a list tile and a checkbox.

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

The following arguments are required:

• value, which determines whether the checkbox is checked. The value can only be null if tristate is true.
• onChanged, which is called when the value of the checkbox should change. It can be set to null to disable the checkbox.
