Exception error after dispose (setstate)

[JTibblesSoftcon]

I use the fader widget to fade text slides in and out - however if the user changes their language (via a provider/notifier) the widget needs to be redrawn with the new language. This causes an issue with the fader being replaced:
"Another exception was thrown: setState() called after dispose(): _FaderState#72c2f(lifecycle state: defunct, not mounted)"

I think this could be fixed if the plugin included a "if (mounted)" check around the setState request.
