Create a new SplitInstallManager.

onCreateNavHostController

protected open fun onCreateNavHostController(navHostController: NavHostController): Unit

Callback for when the NavHostController is created. If you support any custom destination types, their Navigator should be added here to ensure it is available before the navigation graph is inflated / set.
