Estoy escribiendo una aplicación de Android Jetpack Compose, necesito almacenar algunas configuraciones de forma permanente.

Decidí usar androidx.datastore:datastore-preferences:1.0.0 , la he agregado a mi classpath.

De acuerdo con la descripción de https://developer.android.com/topic/libraries/architecture/datastore , agregué esta línea de código a mi archivo kotline en el nivel superior:

val Context.prefsDataStore: DataStore por preferenciasDataStore(nombre = "configuración")

Pero me sale un error de compilación:

 e: ...SettingsViewModel.kt: (13, 50): Property delegate must have a 'getValue(Context, KProperty<*>)' method. None of the following functions is suitable: public abstract operator fun getValue(thisRef: Context, property: KProperty<*>): DataStore<Preferences> defined in kotlin.properties.ReadOnlyProperty

¿Cómo puedo usar las preferencias del almacén de datos?

Mi archivo build.gradle:
