Is it okay to nest sealed classes. So UserData is a part of ModelData, but UserData can also have its own hierarchy with two separate types of UserData, in this case LoginData and AuthenticationData. Or is there any better solution for this?

from my experience, it's fine 🙂

are you sure this example is what you want? Because

UserLoginData

and

UserAuthenticationData

do not extend

ModelData

, and if you try to assign for example an instance of

UserLoginData

to

ModelData

or do an

is

check, you’ll get a complation error. Am I missing something? 🤔

Yeah, my bad it should be

sealed class UserData(...): ModelData() {
		
		data class UserLoginData(...): UserData()
		data class UserAuthenticationData(...): UserData()
	}

Oh okay thanks, I was confused!
