# Compose Multiplatform Expert

Get the shared UI right across platforms, down to the state handling

## What this does

You're building UI meant to work on more than one platform and keep hitting judgment calls: how to hold state, what to theme, what belongs in shared code. This brings patterns for that kind of Compose Multiplatform work. Reach for it while writing visual components or working out what to share.

### Top 3 things it does for you

- Build visual components that work across platforms
- Sort out state handling in a composable
- Decide whether a piece of UI should be shared or platform-specific

## About Compose Multiplatform Expert

This covers Compose Multiplatform UI patterns for shared composables: visual components, state management patterns such as remember, derivedStateOf and produceState, recomposition optimization with @Stable and @Immutable in visual usage, Material3 theming, and custom ImageVector icons.

It also helps with the call on whether a piece of UI belongs in commonMain or should stay platform-specific.

Navigation goes to the android-expert and desktop-expert skills instead, and the Kotlin language side of state and annotations is handled by kotlin-expert, which this complements.
