Navigation 3

Overview

Implement state-driven navigation in Jetpack Compose using Navigation 3. Unlike Navigation Compose, Navigation 3 models navigation as application state rather than through a NavController. This skill covers navigation keys, back stack management, ViewModel scoping, entry decorators, adaptive layouts, deep links, animations, state restoration, and testing.

Setup

Add the Navigation 3 dependencies:

// build.gradle.kts
dependencies {

    implementation("androidx.navigation3:navigation3-runtime:1.0.0-alpha08")
    implementation("androidx.navigation3:navigation3-ui:1.0.0-alpha08")

    // Lifecycle integration
    implementation("androidx.lifecycle:lifecycle-viewmodel-navigation3:2.9.2")
