Refresh auth token in Ktor while using koin

Question

I was using Koin as dependency Injection library to create the ktor HttpClient:

val AppModule = module {
    single { provideClientService() }
}

fun provideClientService(preferences: SharedPreferences): HttpClient {

install(Auth){
    bearer {
        loadTokens {
            BearerTokens(sharedPreferences.getString("accessToken",""))      
        }
    }
}}

but after the user login the accessToken is not updated.

I think it is because of the different scopes in koin. there is 3 kind of scopes in koin:

• single definition : create an object that persists with the entire container lifetime (can't be dropped).

• factory definition : create a new object each time. Short life. No persistence in the container (can't be shared).

• scoped definition : create an object that is persistent tied to the associated scope lifetime.

so I changed the client definition to factory , because I want it to be updated after getting a new token. and now I wonder is it correct?

val AppModule = module {
    factory { provideClientService() }
}
