What problem does it solve?

Identify when to adjust the LazyLayoutCacheWindow to reduce frame drops during high-velocity scrolling by tuning ahead and behind extents.

Core Features & Use Cases

  • Tune ahead/behind cache windows via LazyLayoutCacheWindow(ahead, behind) plumbed through rememberLazyListState and used by LazyColumn (with @OptIn).
  • Use NestedPrefetchScope for items that host inner lazy layouts to warm inner content during the outer prefetch phase.
  • Follow prerequisites (Compose Foundation 1.9+ for cache window support; 1.10+ for pausable prefetch) and verify improvements with Macrobenchmark.

Quick Start

Measure frame timings and then implement a LazyLayoutCacheWindow with ahead and behind values plugged into rememberLazyListState and applied to your LazyColumn.
