Null check operator used on a null value #449

Closed pamafe1976 closed 3 months ago

Hi, I'm getting several crashlytics reports linked to the ShowcaseWidget. Unfortunately theres not much in the stacktrace to help understanding whats going on. Apparently the error is happening only in IOS (to be confirmed)

I'm using the ShowcaseWidget in several screens in my app. I normally put it as parent of the Scaffold widget, since I showcase widgets both on body and on bottomNavigationBar.

Maybe someone with more knowledge of the package can suggest where the problem might be.

Regards
