Using the new nav3 dev builds in a Compose Multiplatform project, and migrating a custom backstack with its own saver (to survive process death on Android), what is the equivalent of saving something parcelable (for typed routes) ?

*Settings.gradle.kts:*
```dependencyResolutionManagement {
    repositories {
        //(...)
        maven { url = URI.create("<https://maven.pkg.jetbrains.space/public/p/compose/dev>") }
    }
}```
*libs.version.toml:*
```[versions]
navigation3 = "1.0.0+dev2849"

[libraries]
androidx-navigation3-runtime = { module = "org.jetbrains.androidx.navigation3:navigation3-runtime", version.ref = "navigation3" }
androidx-navigation3-ui = { module = "org.jetbrains.androidx.navigation3:navigation3-ui", version.ref = "navigation3" }

[bundles]
nav3 = [
    "androidx-navigation3-runtime",
    "androidx-navigation3-ui"
]```
In your composeApp build.gradle.kts:
```commonMain.dependencies {

    implementation(libs.bundles.nav3)
}```
Enjoy :blush:

Niiice, thanks! Had in my todo to try nav3 on Android, will do it on CMP too:)

My rec would be to use kotlinx-serialization.

<@U070RR9Q6BE> What do you mean, just serialize and deserialize into a string manually?

I think KMP SavedState recently migrated in 1.8.2 does that under the hood already

oh, so I can just transform that list into a list of strings, interesting, I'll try that

Coz I couldn't find anything receiving Any or T

That's my guess, I still need to try out Nav3 too and see what are the limitations and whatnot:) Report your findings, would be nice to hear too~

I have one question, is there any documentation or GitHub repo to track the latest version of this library?

Release changes: <https://developer.android.com/jetpack/androidx/releases/navigation3#1.0.0-alpha08>
Examples: <https://github.com/android/nav3-recipes>
Docs: <https://developer.android.com/guide/navigation/navigation-3>

And if you are really curious about development, you can use <https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:navigation3/|cs.android.com>

Is androidx.navigation3:navigation3 and org.jetbrains.androidx.navigation3 are the same?

I don't think it will be the same version for both libraries.

• androidx - Android-only
• org.jetbrains - KMP-compatible

This new talk released yesterday answers to my question :blush:
