  2. Widget? avatar,
  3. required Widget label,
  4. TextStyle? labelStyle,
  5. EdgeInsetsGeometry? labelPadding,
  6. bool selected = false,
  7. required ValueChanged<bool>? onSelected,
  8. Widget? deleteIcon,
  9. VoidCallback? onDeleted,
  10. Color? deleteIconColor,
  11. String? deleteButtonTooltipMessage,
  12. double? pressElevation,
  13. Color? disabledColor,
  14. Color? selectedColor,
  15. String? tooltip,
  16. BorderSide? side,
  17. OutlinedBorder? shape,
  18. Clip clipBehavior = Clip.none,
  19. FocusNode? focusNode,
  20. bool autofocus = false,
  21. MaterialStateProperty<Color?>? color,
  22. Color? backgroundColor,
  23. EdgeInsetsGeometry? padding,
  24. VisualDensity? visualDensity,
  25. MaterialTapTargetSize? materialTapTargetSize,
  26. double? elevation,
  27. Color? shadowColor,
  28. Color? surfaceTintColor,
  29. IconThemeData? iconTheme,
  30. Color? selectedShadowColor,
  31. bool? showCheckmark,
  32. Color? checkmarkColor,
  33. ShapeBorder avatarBorder = const CircleBorder(),
  34. BoxConstraints? avatarBoxConstraints,
  35. BoxConstraints? deleteIconBoxConstraints,
  36. ChipAnimationStyle? chipAnimationStyle,
})

Create a chip that acts like a checkbox.

The selected, label, autofocus, and clipBehavior arguments must not be null. When onSelected is null, the FilterChip will be disabled. The pressElevation and elevation must be null or non-negative. Typically, pressElevation is greater than elevation.
