How do I provide an interface, but give it a concrete class, and then use that interface in another provider? example

single(createdAtStart = true) { ConcreteRandomNameGenerator() }

  single(createdAtStart = true) {
    val random: InterfaceRandomNameGenerator = get()
    val foo = Foo.init(random.getRand()).build()
    foo
  }

I'm currently getting a crash saying that

No definition found for type InterfaceRandomNameGenerator

single<InterfaceRandomNameGenerator> { ConcreteRandomNameGenerator() }

there you go 🙂
