buildWithChild method

  1. @override
Widget buildWithChild(
  1. BuildContext context,
  2. Widget? child
)
override

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) {
  assert(child != null);
  return Positioned(
    key: modifierKey,
    left: left,
    top: top,
    right: right,
    bottom: bottom,
    width: width,
    height: height,
    child: child!,
  );
}
