Memory does not decrease with a large list.

Memory does not decrease with a large list. I tried SliverStaggeredGrid.builder and SliverStaggeredGrid.countBuilder with a large number of tiles. When I scroll, the old item in the grid which disappeared still alive and took lots of my memory. The problem is when my list has many items. App will crash because the memory is not enough. => I tried to change to Gridview.builder. The problem is solved. Gridview.builder release old item which disappeared and rebuild when items are showed on screen.

any one has a solution for this situation?

The reason for this is that all children of the grid are cached indefinitely.

Currently there is no way of disabling this behaviour. However, I have opened PR #188 that allows this.

go with waterfall_flow: ^3.0.1 it working good

I experienced the same problem, which is a deal breaker for me, as I have 1000+ items in the grid. Especially when rotating the phone, it's horrendous to redraw, and I can see it going through all items up to the scroll point. I initially thought there was something wrong with my implementation, but now I see a lot of people with the same problem. I am currently using GridView.builder, which is fast, no problems, except that I'm stuck with same size tiles.

Have you some code I could just copy/paste and run to see where the issue comes from?
