frame8.ScrollRectItemsAdapter.ContentSizeFitterExample Namespace

The prefabhas a disabled ContentSizeFitter added, which will be enabled in UpdateViewsHolder(MyItemViewsHolder)

if the size was not already calculated (in a previous call), then ScheduleComputeVisibilityTwinPass(Boolean) should be called.

After that, as soon as UpdateViewsHolder(MyItemViewsHolder) was called for all visible items, you'll receive a callback to OnItemHeightChangedPreTwinPass(TItemViewsHolder)

(or OnItemWidthChangedPreTwinPass(TItemViewsHolder) for horizontal ScrollRects) for each of them,

where you can disable the content size fitter.

A "Twin" ComputeVisibility(Double) pass is executed after the current one has finished (meaning UpdateViewsHolder(MyItemViewsHolder) was called for all visible items).
