    Use fully qualified ClassName for action method return names.
   
    Using complete ClassName for action return types helps child direction
    classes correctly generate their inherited action method. More precisely
    it allows for deep nested direction classes to correctly import the
    inner NavDirection class generated in a grandfather direction class.

This has been fixed internally and will be available in the next release.

Note that the Kotlin Safe Args plugin (using apply plugin: 'androidx.navigation.safeargs.kotlin') is not affected by this bug, so if you're in a Kotlin only project, consider switching to that as a workaround.

Note that when fixing this issue, we did find another issue, filed as https://issuetracker.google.com/issues/123374541 that *does* affect the Kotlin code gen specifically when using a argument name with the same name as the enum class you've set as the default value (in your example app, the android:name="ToolbarType"). Feel free to star that issue to track progress on that issue and note the workaround listed there).
