Compose Yourself: Designing a Kotlin First UI Toolkit
summary
Jetpack Compose claims a Kotlin-first, declarative UI where UI is a call graph of composable functions, powered by a compiler plugin and live previews in Android Studio Canary. It builds core/foundation/material layers, composes buttons from surface ripple clickable container, enforces single source of truth with controlled components, offers default implementations for complex state like scrolling, and exposes customizable slot APIs. Developer Preview 0.3 is available via Maven artifacts.
