Domain Package

The Domain package contains the essential business logic and core entities of the application.

Domain Package

Model Package​

Defines key data classes.

  • User: Represents a user with properties like id, email, and hasPremiumAccess.
  • AuthProvider: Enum for authentication methods (e.g., GOOGLE, APPLE).

Exceptions Package​

Contains custom exception classes that handle specific error scenarios within the application.

  • UnAuthorizedException: This exception is thrown when a user attempts to perform an operation without being logged in. When you need to perform an operation that requires user authentication, throw the UnAuthorizedException, then, for example, in your ViewModel, you can catch this exception and show an appropriate view to the user. This is how it's implemented in ProfileUiStateHolder. When the user is not authenticated, the exception is caught, and the application navigates to the sign-in screen.
