Is your feature request related to a problem? Please describe.
I don't want a nextButton. I set it to null. But the vertical space it would take is wasted anyway.
Describe the solution you'd like
If nextButton is null, don't bulid a Container with footerContentHeight. Keep it empty, or build it with height = 0.
Describe alternatives you've considered
See above
