Clear all prefs at once

[P1NG2WIN]

In my app, user can log out so i must clear all saved info.

I have class AppCleaner that listens to user events and do clean

object AppCleaner: KoinComponent {

    private lateinit var applicationContext: Context

    private val roomDatabase by inject<Database>()
    private val userLifecycle by inject<Lifecycle>(userLifecycleQualifier)

    fun init(context: Context) {
        applicationContext = context.applicationContext

        GlobalScope.launch {
            userLifecycle.stopped()
                .collect {
                    clearCache()
                    clearRoom()
                    clearSharedPrefs()
                }
        }
    }

    private fun clearRoom() { roomDatabase.clearAllTables() }

    private fun clearSharedPrefs() {
        applicationContext.filesDir.parentFile?.let { root ->
            File(root, "shared_prefs")
                .list()
                ?.let { for (fileName in it) {
                    applicationContext.getSharedPreferences(
                        fileName.replace(".xml", ""),
                        Service.MODE_PRIVATE
                    ).edit { clear() }
                } }
        }
    }

    private fun clearBinaryPrefs() {
        TODO()
    }

    private fun clearCache() { applicationContext.cacheDir.deleteRecursively() }

}

Can you help me with solution that will clean all binary prefs?
