Very informative. Thanx

Thanx a lot! Love your style. I once checked the sources of GetX GetBuilder and surprise! in version 4 it uses setState(), but in version 5 marksNeedRebuild(). Will be the latter more performant than the first?

Thanx for the article. You use Visibility to show an appropriate view. Is it to eliminate if...else? Any drawbacks of such a technique? Are hidden widget trees still there... or not?
