buildWithComponentDirection function

Widget buildWithComponentDirection(BuildContext context, ComponentDirection? direction, WidgetBuilder builder)

Builds a node under its explicit direction, or directly under context when the node inherits the panel direction.

The inner Builder is load-bearing for host registries: their callback's own context must already see the override. Merely wrapping the Widget they returned would make its descendants correct while any direction-sensitive values computed inside the callback still used the host direction.

Implementation

Widget buildWithComponentDirection(
  BuildContext context,
  ComponentDirection? direction,
  WidgetBuilder builder,
) {
  if (direction == null) return builder(context);

  return Directionality(
    textDirection: switch (direction) {
      ComponentDirection.ltr => TextDirection.ltr,
      ComponentDirection.rtl => TextDirection.rtl,
    },
    child: Builder(builder: builder),
  );
}
