How to add a header

[AhmadFadilB]

How do you add a header or just any widgets above the listview but they are on the same scrollview. It's possible to just use a column and put the azlistview last. But the other widgets would just simlpy stay at the top of the screen and can't be scrolled. I think it's possible if the azlistview has a shrinkWrap and physics property so we can wrap it inside a singlechildscrollview , but alas it doesn't.

I just want to show a searchbar at the top with the listview below it.
