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? 🤔

[Ive Vasiljevic]

Yeah, my bad it should be

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

Oh okay thanks, I was confused!
