  11. String? tooltip,
  12. BorderSide? side,
  13. OutlinedBorder? shape,
  14. Clip clipBehavior = Clip.none,
  15. FocusNode? focusNode,
  16. bool autofocus = false,
  17. MaterialStateProperty<Color?>? color,
  18. Color? backgroundColor,
  19. EdgeInsetsGeometry? padding,
  20. VisualDensity? visualDensity,
  21. MaterialTapTargetSize? materialTapTargetSize,
  22. double? elevation,
  23. Color? shadowColor,
  24. Color? surfaceTintColor,
  25. IconThemeData? iconTheme,
  26. Color? selectedShadowColor,
  27. bool? showCheckmark,
  28. Color? checkmarkColor,
  29. ShapeBorder avatarBorder = const CircleBorder()}
)

Create a chip that acts like a radio button.

The label, selected, autofocus, and clipBehavior arguments must not be null. The pressElevation and elevation must be null or non-negative. Typically, pressElevation is greater than elevation.
