Jetpack Navigation 3

Priority: P1 (HIGH)

Guide for implementing and migrating to Navigation 3 in Jetpack Compose.

Core concepts

Navigation 3 replaces the previous NavHost/NavController pattern with a simpler, state-driven approach:

• Routes are Kotlin data objects/classes (not strings).
• Back stack is a plain mutableStateListOf<Any>.
• NavDisplay renders the current route based on a lambda.

Basic usage

val backStack = remember { mutableStateListOf<Any>(RouteHome) }
