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) {
  return Observer(builder: (ctx) {
    final out = _observerFn(ctx);
    return ProxyProvider0<TOutput>(
        lazy: false, update: (_, __) => out, child: child);
  });
}
