What does the empty parentheses after the onPressed property mean in Dart?

Question

I know the syntax for calling a function after onPressed and onTap for a widget. There are two options We can use either the () => functio

Answer 1

I've learned to treat the empty parentheses as a build first then with the returned value execute this function.

I ran into an issue using the second method you posted where flutter would crash stating "cannot build because the framework is already building" and found this post on StackOverflow which may give you a better idea of what it means. Flutter - Cannot build because the frawework is already building
