NestedGraph destinations not in parent NavGraphSpec.allDestinations

[s0nance]

Hello!

I encountered an issue where calling my current NavGraph .allDestinations extension is not returning the nested nav graphs destinations.

Here is my generated tree:

* * 🗺️[MenuNavGraph]
* * ∙∙∙∙∙∙∙∙↳🗺️🏁[Page1NavGraph]
* * ∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙↳📍🏁[Page1Screen]
* * ∙∙∙∙∙∙∙∙↳🗺️[SettingsNavGraph]
* * ∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙↳📍🏁[SettingsScreen]
* * ∙∙∙∙∙∙∙∙↳🗺️[FromSettingsLoginGraph]
* * ∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙↳📍🏁[LoginScreen]
* * ∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙↳🗺️[FromSettingsRegisterGraph]
* * ∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙↳📍🏁[RegisterScreen]
* * ∙∙∙∙∙∙∙∙↳🗺️[Page2NavGraph]
* * ∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙↳📍🏁[Page2Route]
* * ∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙↳📍[Page2-1Route]
* * ∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙↳📍[Page2-3Route]
*

I expect the extension to return, for FromSettingsLoginGraph, the given destinations:
[FromSettingsLoginLoginScreenDestination, FromSettingsRegisterRegisterScreenDestination], but it seems to only return FromSettingsLoginLoginScreenDestination.

Is this an expected behavior ?

I used a small function to check if my current destination is well a part of the nested navigation:

appCurrentDestinationState?.route?.let {
   topLevelDestination.graph.findDestination(it) // here topLevelDestination represents FromSettingsLoginGraph
} != null

and it returns true when I navigate to (so when appCurrentDestinationState route equals:) FromSettingsRegisterRegisterScreenDestination. So it seems it is indeed a part of the nested graphs!

By looking at your code, inside the SpecExtension.kt file, it seems you are recursively returning all destinations, even those from nestedNavGraphs, so I guess it is a bug?

I'm looking forward to hear your advice on this! Thank you

No problem, it's been a pleasure!
