Flutter Multi-User Theming App

This is a Flutter application that demonstrates a scalable and maintainable approach to handling different themes for multiple user types. The project leverages the Riverpod state management library and employs the Factory and Strategy design patterns to create a clean, organized codebase.

Features

• Multi-User Theming: The app's theme dynamically changes based on the logged-in user's type (basic, premium, or admin).

• State Management with Riverpod: User state is managed globally using a StateProvider, allowing the UI to reactively update when the user changes.

• Factory Pattern: A UserFactory class centralizes the logic for creating and configuring a User object, ensuring that each user type is correctly initialized with its specific features.

• Strategy Pattern: The Feature abstract class and its concrete implementations (BasicFeature, AdvancedFeature, AdminFeature) define different behaviors (e.g., canEdit()), which are then applied to each user type. This makes the code highly extensible without large if/else statements.

• Modular Code: Themes for each user type are defined as separate ThemeData objects, keeping the styling logic distinct and easy to modify.
