WxIcon(
  Icons.star,
  color: _color,
  opacity: _opacity,
  size: _size,
  scale: _scale,
  rotate: _rotate,
  flipX: _flipX,
  flipY: _flipY,
)

IconButton(
  onPressed: _toggleSelected,
  icon: WxToggleIcon(
    Icons.star,
    selected: _selected,
    style: WxDrivenToggleIconStyle.scaleDown(
      size: 24,
      rotate: 45,
      selectedStyle: const WxToggleIconStyle(rotate: 0),
    ),
  ),
)
