Radio<T>.adaptive constructor

const Radio<T>.adaptive(
  1. {Key? key,
  2. required T value,
  3. required T? groupValue,
  4. required ValueChanged<T?>? onChanged,
  5. MouseCursor? mouseCursor,
  6. bool toggleable = false,
  7. Color? activeColor,
  8. MaterialStateProperty<Color?>? fillColor,
  9. Color? focusColor,
  10. Color? hoverColor,
  11. MaterialStateProperty<Color?>? overlayColor,
  12. double? splashRadius,
  13. MaterialTapTargetSize? materialTapTargetSize,
  14. VisualDensity? visualDensity,
  15. FocusNode? focusNode,
  16. bool autofocus = false,
  17. bool useCupertinoCheckmarkStyle = false}
)

Creates an adaptive Radio based on whether the target platform is iOS or macOS, following Material design's Cross-platform guidelines.

On iOS and macOS, this constructor creates a CupertinoRadio, which has matching functionality and presentation as Material checkboxes, and are the graphics expected on iOS. On other platforms, this creates a Material design Radio.

If a CupertinoRadio is created, the following parameters are ignored: mouseCursor, fillColor, hoverColor, overlayColor, splashRadius, materialTapTargetSize, visualDensity.

useCupertinoCheckmarkStyle is used only if a CupertinoRadio is created.

The target platform is based on the current Theme: ThemeData.platform.
