NestedPrefetchScope

fun schedulePrecomposition(index: Int): Unit

Requests a child index to be precomposed as part of the prefetch of a parent LazyLayout.

The prefetch will only do the precomposition for the new item. If you also want to premeasure please use schedulePrecompositionAndPremeasure.

fun schedulePrecompositionAndPremeasure(index: Int, constraints: Constraints): Unit

Requests a child index to be precomposed and premeasured as part of the prefetch of a parent LazyLayout. If you just want to precompose an item use schedulePrecomposition instead.

open fun schedulePrefetch(index: Int): Unit

Requests a child index to be prefetched as part of the prefetch of a parent LazyLayout.

The prefetch will only do the precomposition for the new item. If you also want to premeasure please use a second overload accepting a Constraints param.

open fun schedulePrefetch(index: Int, constraints: Constraints): Unit

Requests a child index to be prefetched as part of the prefetch of a parent LazyLayout.

open val nestedPrefetchItemCount: Int

The projected number of nested items that should be prefetched during a Nested Prefetching of an internal LazyLayout. This will return -1 if a projection isn't available yet. The parent Lazy Layout will use information about an item's content type and number of visible items to calculate the necessary number of items that a child layout will need to prefetch.
