it caused a problem that not found this API_KEY when I compiled the project.

StateFlow won't emit the same value twice.
For example, if we enter a screen and then press the android back button (without using navigationManager), then we will not be able to navigate by the same route.

I struggled a bit with the part with arguments. I think there is something missing in the Arch.

navigationManager.commands.collectAsState().value.also { command ->
if (command.destination.isNotEmpty()) {
navController.navigate(command.destination)
}
}

Can cause nullpointer exceptions on recomposition because the navgraph is not initialized yet. It shoudl be something like:
LaunchedEffect(navigationManager.commands){
navigationManager.commands.collect{ command ->
if (command.destination.isNotEmpty()) {
navController.navigate(command.destination)
}
}
}

I added NavOptionsBuilder

interface NavigationCommand {
    val arguments: List<NamedNavArgument>
    val destination: String
    val builder: NavOptionsBuilder.() -> Unit
}

but I cannot access start navigation because I don't have reference on navController graph,

Hello!

I hope you are doing well!

We are a security research team. Our tool automatically detected a vulnerability in this repository. We want to disclose it responsibly. GitHub has a feature called Private vulnerability reporting, which enables security research to privately disclose a vulnerability. Unfortunately, it is not enabled for this repository.

Can you enable it, so that we can report it?

Thanks in advance!

PS: you can read about how to enable private vulnerability reporting here: https://docs.github.com/en/code-security/security-advisories/repository-security-advisories/configuring-private-vulnerability-reporting-for-a-repository

First I'm not sure if this is an issue in your code base or not, but we implemented something very similar but with RxJava. I left a comment on your great blog https://medium.com/google-developer-experts/modular-navigation-with-jetpack-compose-fda9f6b2bef7 that explains how the MainActivity setContent{} block may be getting recomposed. Figured I'd share our learnings with you incase you see it yourself too.

Here's the comment:
Great article and we are exploring this pattern. We did run into an issue where the commands were being subscribed to as state (RxJava .subscribeAsState(...) ) and that cause the setContent{} block of code to be recomposed. This was easily seen as we were using a black screen, and anytime we navigated it would flash white when setContent{} was hit again. We were able to get around this by using a normal Rxjava .subscribe() pattern, but needed to ensure we were on the main thread prior to calling our navController object. I'm thinking the same could be done via coroutines, but I'm not familiar with them yet. Hope this helps others in the future.
