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) {
  if (delegate == null) {
    return SelectionContainer.disabled(
      key: modifierKey,
      child: child!,
    );
  }
  return SelectionContainer(
    key: modifierKey,
    delegate: delegate!,
    child: child!,
  );
}
