Based on the child measurements, the parent node determines the exact coordinates of each child and places them on the screen. Phase 3: Drawing (How to show)
Recomposition is the process of re-executing Composable functions when their underlying data changes. To prevent performance degradation, the Compose compiler optimizes this cycle using . Stable vs. Unstable Types When you annotate a function with @Composable ,
