This terminology is a bit confusing, since you can optionally provide an itemAnchor.

 

forum? Remember that in our flow layout, we needed to mathematically determine how much total horizontal spacing our layout required to determine our item size, and we also needed to specify minimumInteritemSpacingminimumLineSpacingand sectionInset to get everything working perfectly.
