MultiChildRenderObjectWidget class

A superclass for RenderObjectWidgets that configure RenderObject subclasses that have a single list of children. (This superclass only provides the storage for that child list, it doesn't actually provide the updating logic.)

This will return a RenderObject mixing in ContainerRenderObjectMixin, which provides the necessary functionality to visit the children of the container render object (the render object belonging to the children widgets). Typically, this is a RenderBox with RenderBoxContainerDefaultsMixin.
