I doubt we’ll ever see an official navigation library, because navigation is somewhat out of the scope of Compose. Compose is focused on the UI layer of the app, but navigation gets into the territory of app architecture. And the Jetpack navigation library is very closely tied to Android, and I wouldn’t expect to see it ported to KMM like some of the other Jetpack libraries are.
If you’re looking for a simpler routing option than Decompose or Voyager, I’ve built
Ballast Navigation intentionally as just the backstack manager without being tied directly to Compose or anything else.
