I am using a scroll view that hides my toolbar while scrolling, I don't want my toolbar to hide while scrolling

Question

I am making a register screen, that has a toolbar on top of it. When I scroll down the toolbar hides(goes up). I don't want my toolbar to scroll when I am scrolling. I don't want to use adjust resize or adjust pan because then the other parts then don't work correctly. I tried with appbar but it doesn't work. PS I hided some of my edit texts in body. Here is my design code
