Understanding Jetpack Compose Layout Process: Composition, Measurement, and Modifier Nodes

Jetpack Compose’s layout process consists of three steps—measuring children, deciding the parent’s size, and placing children—driven by a MeasurePolicy that respects explicit Constraints, while Modifier nodes adjust those constraints and intrinsic measurements provide size hints, enabling efficient, declarative UI rendering.
