kotlin-multiplatform-compose-state-container

When to Use This Skill

Use when you need to:

• Decide whether state belongs in remember, rememberSaveable, or a ViewModel
• Understand what "survives recomposition" vs "survives config change" actually means
• Implement a custom Saver for rememberSaveable with a non-bundleable type
• Scope a ViewModel to a nav back-stack entry vs the whole nav graph
• Diagnose state being lost on screen rotation or back navigation

Trigger keywords: remember vs ViewModel, rememberSaveable, state container, when to use ViewModel, ephemeral state, state survival, config change state, process death state, custom Saver, nav-scoped ViewModel, state lost on rotation.

Freshness rule: Compose state survival and nav-scoped ViewModel APIs change with lifecycle and navigation releases — recheck the Jetpack and CMP docs before upgrading.
