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 defaultTheme = Theme.of(context);
  final brightness = MediaQuery.platformBrightnessOf(context);
  return Theme(
    data: _defaultMaterialTheme(
      defaultTheme: defaultTheme,
      brightness: brightness,
    ),
    child: child ?? const SizedBox.shrink(),
  );
}
