Understanding Compose modifiers and how their order affects UI
summary
Claim: Jetpack Compose modifiers are the core drivers of layout, drawing and input, not mere properties, and modifier order changes constraints and drawing. The presentation explains the two-phase behavior — layout then draw — and shows surprising specifics: a second fixed size is ignored, clip cuts later borders, and offset relocates but keeps earlier clip bounds. A playable Modifier Guessing Game and the node APIs (layout/draw/semantic/pointer) demonstrate patterns and a one‑node implementation that improves power and performance.
