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 SingleChildStatelessWidget. It may also be called again with a different child, without this widget being recreated.

Implementation

@override
Widget buildWithChild(BuildContext context, Widget? child) {
  final mediaQuery = MediaQuery.of(context);
  return Stack(
    children: [
      child!,
      if (showPadding)
        _Padding(
          label: 'padding',
          color: Colors.red,
          padding: mediaQuery.padding,
          alignment: Alignment.topLeft,
        ),
      if (showViewPadding)
        _Padding(
          label: 'viewPadding',
          color: Colors.blue,
          padding: mediaQuery.viewPadding,
          alignment: Alignment.topRight,
        ),
      if (showViewInsets)
        _Padding(
          label: 'viewInsets',
          color: Colors.green,
          padding: mediaQuery.viewInsets,
          alignment: Alignment.center,
        ),
      if (showSize) const _Size(),
    ],
  );
