Question

post is not positioned under AppBar when I clicked on the picture except first. I want to make it like Instagram's function. How can I fix it?

Answer 1

If you want to make it work, do a logic to calculate the space and set the value directly.

If you use

scrollController.animateTo(180.0,
    duration: Duration(milliseconds: 500), curve: Curves.ease);
