MultiNavCompose 
Android library for multi-module navigation built on top of Jetpack Navigation Compose.
The goal of this library is to simplify the setup for multi-module navigation with Jetpack Navigation Compose.
Setup
Add jitpack.io url as maven repository:
repositories {
...
maven { url 'https://jitpack.io' }
}
Add dependency into build.gradle:
dependencies {
implementation 'com.github.jeziellago:multinavcompose:TAG'
}
1. Create a NavComposableModule
Make your composables internal and expose only a NavComposableModule for each module.
// module :posts
val postsNavModule = NavComposableModule { graph, navController ->
graph.composable(POSTS_ROUTE) {
PostsScreen(onClick = { postId ->
navController.navigate("$POST_DETAIL_ROUTE/$postId")
})
}
}
You also can have nested graphs:
// module :posts
val postsNavModule = NavComposableModule { graph, navController ->
graph.navigation(startDestination = POSTS_ROUTE, route = POSTS) {
composable(POSTS_ROUTE) {
PostsScreen(onClick = { postId ->
navController.navigate("$POST_DETAIL_ROUTE/$postId")
})
}
...
}
}
2. Register the NavComposeModule`s
Single NavHost
Call multiNavModules and put all the NavComposeModule's.
For single activity applications (and only a
NavHost) you should register the NavComposeModule inonCreateon Application.
class MyApplication : Application() {
override fun onCreate() {
super.onCreate()
// Register all NavComposeModules
multiNavModules(homeNavModule, postsNavModule, postDetailNavModule)
}
}
Multiple NavHost's
If you have multiple NavHost's, a key is required on registering each of them:
// feed nav graph
multiNavModules(feedNavModule) { FEED_GRAPH }
// posts nav graph
multiNavModules(postsNavModule, postDetailNavModule) { POST_GRAPH }
3. Setup on NavHost
The loadMultiNavComposables loads the composables into NavHost.
Single NavHost
NavHost(navController = navController, startDestination = HOME) {
loadMultiNavComposables(navController)
}
Multiple NavHost
If you have multiple NavHost's, a key is required too (see POSTS_GRAPH).
NavHost(navController = navController, startDestination = POSTS_ROUTE) {
loadMultiNavComposables(navController, POSTS_GRAPH)
}
