I want to make a container collapse (disappear) when scroll down, and expand (appear again) when scroll up. Just like the search bar in microsoft teams mobile.

I tried to do it using SliverAppBar and it worked but the ListView became lagging and had problems. Is there any way to do it without SliverAppBar?

I think you should only replace AppBar Widget with SliverAppBar

hope I could help.
