How to share object between routes

[N7ghtm4r3]

Hi, I'm trying to share a custom object between two routes with the stateHolder, but is the clean way to do that because sometimes the navigation starts after that the stateHolder has been set the custom object, but sometimes, instead, the navigation starts before the custom object has been set. The following snippet is how I have implemented that:

MainScope().launch {
    val currentEntry = navigator.currentEntry.first()
    val stateHolder = currentEntry?.stateHolder
    stateHolder?.set("key", customObject)
}
navigator.navigate("route")

Scene

scene(
   route = "route"
) { backstackEntry ->
      val stateHolder = backstackEntry.stateHolder
      val customObject: Any = stateHolder[key]!! // here the application crashes because the object has not been set when navigated here
      ...
}

May I have to wait before navigate? But if navigate inside the MainScope the navigation never happens

I would recommend don't share object between routes, I'd like to recommend follow the Android Architecture Guideline: https://developer.android.com/topic/architecture
In short: It's better to follow "single source of truth", you can have a repository that store the object, and call it from different routes.

Thank you for the tip!

But if I need to do that in this case how can I do that?

I have followed your recommendation to implement a clean navigation
