RenderBoxChildLayout class

Adapter that makes a RenderBox compatible with the flexbox layout system.

RenderBoxChildLayout implements the ChildLayout interface for Flutter's RenderBox objects, allowing them to participate in flexbox layouts. It provides the bridge between Flutter's rendering system and the flexbox layout algorithm, handling layout calculations, caching, and positioning for individual render box children.
