SelectionRegistrarScope class

An inherited widget to host a SelectionRegistrar for the subtree.

Use SelectionContainer.maybeOf to get the SelectionRegistrar from a context.

This widget is automatically created as part of SelectionContainer and is generally not used directly, except for disabling selection for a part of subtree. In that case, one can wrap the subtree with SelectionContainer.disabled.
