How to scroll to a specified position? about flutter_staggered_grid_view HOT 5 CLOSED

I'm facing the same problem: bring an item into view by item index. It would be very useful.

from flutter_staggered_grid_view.

Is there a way to scroll if I calculate the offset manually, though? In my case, in the idea I'm working on, the cells all have a fixed height, so it would be easy for me. Scrolling to a specific position is something I really need.

It would really be nice to be able to bring widget index X into view, though.

I believe it's possible to scroll to a certain offset, but I didn't try it, because, as @wilin52 mentioned, it's complicated, as my cells might not have the same height, and/or the number of columns might change depending on the screen size/orientation.

You can scroll programmatically by attaching a ScrollController to the grid, and then calling this:
Timer(
Duration(milliseconds: 200),
() => _scrollController.animateTo(_offset,
duration: const Duration(milliseconds: 500), curve: Curves.ease));
I used a timer in my case, otherwise I get an exception that the ScrollController is not yet attached. You might not need it.
Give it a try.

the issue can be closed , I think .
There is a solution: https://github.com/quire-io/scroll-to-index
The theory of scroll_to_index is simple, but not efficient. The best way to resolve it is that scrollController support scroll to certain index like android native instead of offset .
