deferring-state-reads

You can defer state reads in Jetpack Compose to the Layout or Draw phases by using lambda-based modifiers, which ensure state reads occur in the appropriate phase instead of triggering recomposition.

Deferring state reads in Jetpack Compose is a performance optimization technique that moves state reads from the Composition phase to the Layout or Draw phases, preventing unnecessary recompositions for frequently-changing state.

You optimize Jetpack Compose animations and scrolling by deferring state reads to the Layout or Draw phases using lambda-based modifiers, which reduces unnecessary recompositions for UI elements depending on frequently-changing state.

Yes, understanding Jetpack Compose's three-phase model is required to defer state reads, as you must analyze your code to identify Composition phase state reads and move them to the Layout or Draw phases.

You should defer state reads in Jetpack Compose when UI elements depend on frequently-changing state, such as during animations and scrolling, where preventing unnecessary recompositions directly enhances UI smoothness.
