cardBuilder property
Specialized builder for card mode only, of type Widget Function(BuildContext, T, T)?, receiving context,
the option, and current selected value. It enables visual feedback such as borders, colors, or icons for the
active selection; if null, falls back to itemBuilder. This field enhances interactivity in CardCarousel
within the ArcaneFieldWrapper, ideal for touch-based selections.
Implementation
final Widget Function(BuildContext, T, T)? cardBuilder;
