Overview

Navigation 3 is a Compose-first navigation library that replaces string-based routes with type-safe @Serializable data classes. This sample covers its core concepts — routing, back stack management, and deep links — as a reference before migrating a production app.

Tech Stack

• Kotlin
• Jetpack Compose
• Navigation 3 1.0.0
• kotlinx-serialization

Features

• Type-safe routing with @Serializable + NavKey
• Basic screen transitions via NavDisplay
• Deep link handling
• Back stack manipulation

Getting Started

git clone https://github.com/komodgn/compose-nav3-sample.git

Open in Android Studio and run.

Version Note

Navigation 3 requires a compatible Compose BOM. This project uses:

Library	Version
Navigation 3	1.0.0
Compose BOM	2025.09.01 (compose-bom-alpha)
Activity Compose	1.9.3
Lifecycle	2.10.0

Using a newer Compose BOM (e.g. 2026.xx.xx) will cause runtime crashes due to navigationevent version conflicts.
