voyager VS Decompose

KMP use cases increasing, developers migrating or creating your projects to KMP, no routing system or navigation available to KMP (Except Voyager), that was the opportunity to create one.

If I were to start a project right now, I'd use https://github.com/adrielcafe/voyager although, it doesn't support Web Canvas or iOS yet I don't think.

Voyager has some bugs (apparently SavedStateHandle doesn't work and the PR is open since Nov 24), Appyx is nice but I hear it's laggy (but honestly, everything in Compose is laggy all the time, so if you use Compose, that's pretty standard tbh), I don't know enough about Navigation-Reimagined to tell you, Compose-Destinations is a codegenerator over Navigation-Compose so you drag in Accompanist-Navigation to have basic screen transitions which is pre-alpha tech.

Yes, I've checked (it doesn't). I've also read AndroidScreenLifecycleOwner's source code, and I don't see a way for it to ever go to the ON_PAUSE state.

Using any of the 5 prominent community alternatives is a better approach (even though most people hoping to use the docs as if it was like, written for stable code, will muck around with their apps crashing if the user inputs a & symbol). I have this thing but I'd consider taking a look at https://github.com/adrielcafe/voyager or maybe https://github.com/olshevski/compose-navigation-reimagined

I use Decompose, although I also have a kmp project which that supports. I find the compose extensions providing a very easy API when integrating with compose.

For one of our apps we used https://arkivanov.github.io/Decompose/ for navigation. It is mentioned in the Compose Multiplatform repo, but we found it pretty obscure to use and it has some confusing concepts built in.

View model is Googles recommended approach, but there are other approaches out their you can use like decompose

When you are building your app in KMM, sometimes you need to pack some libraries along with project files in the shared module. For example if you are using Decompose you need to access it's Value class in Swift.

I don't have much experience with conductor, so I'm curious what your concerns about lifecycle is lacking compared to fragments? But if your team already knows that framework I might just stick with views over fragments. I see there is a compose integration if you do ever plan on picking that up with conductor. Otherwise compose makes fragments obsolete and your team already knows conductor. I do agree the navigation story in compose is not mature especially after jetpack compose navigation. But there are other 3rd party libraries like compose destinations or decompose, but would be nice to see something better 1st party.

I personally like decompose for its testability, clear separation of concerns, and apis for compose animations. Plus it's multiplatform so you can use it for other kmp targets.

Full discretion, all my new apps are built using mvi with MVIKotlin and decompose for the compose extensions for navigation animations. A sample project I have built with that architecture can be found here.
