SemanticsTag? tagForChildren

A tag to be applied to the child SemanticsNodes of this widget.

The tag is added to all child SemanticsNodes that pass through the RenderObject corresponding to this widget while looking to be attached to a parent SemanticsNode.

Tags are used to communicate to a parent SemanticsNode that a child SemanticsNode was passed through a particular RenderObject. The parent can use this information to determine the shape of the semantics tree.
