FlipView setState is called after dispose

[shaxxx]

In certain conditions FlipView causes exception

setState() called after dispose()

which is thrown two times when I flip the card.
Details in the screenshot

In my case AnimateList has multiple flip items, being rebuild multiple times.
Sometimes items are build as flipviews, sometimes not.
Exception occurs when Flipview is removed from view.

When this.mounted check is applied no exception is thrown.
Thanks for the widget!
