buildWithChild method
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 Baseline(
key: modifierKey,
baseline: baseline,
baselineType: baselineType,
child: child,
);
}
