debugVisitOnstageChildren method
inherited
Calls the argument for each child considered onstage.
Classes like Offstage
and Overlay
override this method to hide their
children.
Being onstage affects the element's discoverability during testing when
you use Flutter's Finder
objects. For example, when you instruct the
test framework to tap on a widget, by default the finder will look for
onstage elements and ignore the offstage ones.
The default implementation defers to visitChildren and therefore treats the element as onstage.
