ask; navigation

[moonwalkin]

Each of the feature modules has navigation, but I don't see the navigation library connection anywhere except for the app module. I looked at all the plugins, but I didn't see it there either. Please help me to understand how it works.

each feature module applies this convention plugin

I saw this, but where is the navigation connected? i saw only hilt navigation

[TerryQuiet]

not sure, but maybe you're looking for this
https://github.com/android/nowinandroid/blob/main/feature/interests/src/main/kotlin/com/google/samples/apps/nowinandroid/feature/interests/navigation/InterestsNavigation.kt
every feature module have extension function on NavGraphBuilder and NavController
and NavGraph uses those extension functions to build the app graph.

I understand that each module has extensions but I'm interested in something else

To make an extension on some class, there must be a dependency, in this case: androidx.navigation:navigation-compose.

Modules do not have this dependency.
There is a plugin AndroidFeatureConventionPlugin that used to have this dependency
https://github.com/android/nowinandroid/blob/8fc2e15e73de9de90ef535ffb2ca62c051d865a8/build-logic/convention/src/main/kotlin/AndroidFeatureConventionPlugin.kt (old version of the file)
Now this dependency is gone, but it still works
https://github.com/android/nowinandroid/blob/main/build-logic/convention/src/main/kotlin/AndroidFeatureConventionPlugin.kt (current file version)

I hope you understand what I mean

https://mvnrepository.com/artifact/androidx.hilt/hilt-navigation-compose/1.2.0
we can see here that hilt comes with those dependencies.
also we can use gradle task too see all the transitive dependencies ./gradlew :feature:foryou:dependencies

Hilt-navigation-compose has the dependency of navigation-compose, so that it is fine that don't use navigation-compose.
