buildWithChild method

@override Widget buildWithChild(BuildContext context, Widget? child)

A build method that receives an extra child parameter.

This method may be called with a child different from the parameter passed to the constructor of SingleChildStatelessModifier. It may also be called again with a different child, without this widget being recreated.

Implementation

@override
Widget buildWithChild(BuildContext context, Widget? child) {
  return SliverAnimatedOpacity(
    opacity: opacity,
    duration: duration,
    alwaysIncludeSemantics: alwaysIncludeSemantics,
    curve: curve,
    onEnd: onEnd,
    sliver: child,
  );
}
