Architecture

Pokedex is built using the MVVM (Model-View-ViewModel) Architecture, a design pattern that separates the user interface logic from the business logic. This architecture enhances code organization, maintainability, and testability.

MVVM Components

1. Model

   • Represents the data and business logic of the application
   • Handles data retrieval, storage, and manipulation

2. View

   • The user interface that displays data from the model
   • Observes and reacts to state changes in the ViewModel

3. ViewModel

   • Acts as a bridge between the Model and the View
   • Prepares and manages data for display in the View
   • Handles UI-related tasks such as:
     • Data validation
     • Error handling
   • Provides a clean API for the View to interact with

4. Hilt

   • Handles dependency injection.

Benefits of MVVM in Pokedex

• Separation of Concerns: Clear distinction between UI, data, and business logic
• Testability: Easier to write unit tests for ViewModels and Models
• Maintainability: Changes in one component have minimal impact on others
• Scalability: Facilitates easier addition of new features and modifications
