what is the difference between these two code ?

class VerifyAppIntegrityUseCase(
    val authRepository: AuthRepository,
    val workbenchUserRepository: WorkbenchUserRepository,
    val menuRepository: MenuRepository,
    val subscriptionRepository: SubscriptionRepository,
    val adkarRepository: AdkarRepository,
    val securedKeyValueStoreRepository: SecuredKeyValueStoreRepository,
 >>>   dispatcher: CoroutineDispatcher
) :
    AuthenticatedFlowUseCase<Unit, Unit>(authRepository, dispatcher), UseCaseScope

class VerifyAppIntegrityUseCase(
    val authRepository: AuthRepository,
    val workbenchUserRepository: WorkbenchUserRepository,
    val menuRepository: MenuRepository,
    val subscriptionRepository: SubscriptionRepository,
    val adkarRepository: AdkarRepository,
    val securedKeyValueStoreRepository: SecuredKeyValueStoreRepository,
>>> val dispatcher: CoroutineDispatcher
) :
    AuthenticatedFlowUseCase<Unit, Unit>(authRepository, dispatcher), UseCaseScope

why would kotlin give such a dual option here, both options allow us to pass it to the Super class constructor

[Paul Woitaschek]

Well if you have it as a val, you can also use it inside the class and access it from the outside

[Ciaran Sloan]

The difference here is how this Kotlin code compiles to Java. In the case of specifying val on the constructor property, you are defining this as a global variable in the class, which is instantiated in the constructor.

In the case of not specifying val the property is not a global variable, but is just a constructor scoped property that can only be used when the instance of the class is being generated via the constructor.
