Getting the currently Selected Page from a Swipe Container
I'm trying to save the current selected page for a SwipeContainer in the tearDownScreen handler when a screen closes, so when that screen reopens the user is taken back to the same page they left it on.
However, I can't seem to find a way to access what the currently selected page is for the SwipeContainer. I see there is a method to set the selected page. I also see that the widget maintains the CurrentPage internally. But, I can't seem to get access to it from the view.
