Would someone have a moment to explain what the Default* creator functions are for?

In the RootComponent we do

private fun child(config: Config, componentContext: ComponentContext): RootComponent.Child =
        when (config) {
            is Config.login -> RootComponent.Child.LoginChild(loginComponent(componentContext))
        }

fun loginComponent just does

fun loginComponent(componentContext: ComponentContext): LoginComponent =
    DefaultLoginComponent(
        componentContext = componentContext,
        onLogin = { username, password ->
            println("LoginComponent.onSubmit: username=$username, password=$password")
        }
    )

Is there a specific reason that the quickstart doesn’t just use DefaultLoginComponent directly?

Nvm, I got it — If you keep loginComponent creator in the rootComponent it has access to stuff like navigator . I suppose you could pass it to Default* but then Default* is strictly related to the navigator so you can’t pass a different instance for when testing etc

TL:DR; it’s a factory

It's just separation of concerns, nothing special.

Yep 😄, just gotta jog the ole memory
