app

This project follows a Clean Architecture approach combined with MVVM and is highly Modularized to ensure scalability, testability, and separation of concerns.

Architecture

The project is divided into three main layers:

1. Data Layer: Responsible for data persistence and retrieval (Room, Network).

2. Domain Layer: Contains the core business logic, models, and Use Cases. This layer is pure Kotlin/Java and has no dependencies on the Android framework.

3. UI Layer: Handles the display of information and user interaction using Jetpack Compose and ViewModels.

Modularization

The project is modularized by feature and by layer:

• :app: The main entry point of the application.

• :demosales-ui:*: Modules containing UI components for specific features (Products, Sales, Clients).

• :demosales-domain:*: Pure Kotlin modules containing the business logic for each feature.

• :demosales-data:*: Modules responsible for data management (Room entities, DAOs, Repositories).

This structure allows for independent development of features and faster build times.

App Module Folder Structure

The :app module acts as the orchestrator of the application, connecting all feature modules and providing global configurations.

• com.imecatro.demosales.di: Contains Hilt modules for dependency injection, providing database instances, repositories, and use cases to the rest of the application.

• com.imecatro.demosales.ui: Houses top-level UI components, such as the AdaptiveScaffold, which handles the main navigation layout (rail, drawer, or bottom bar) based on screen size.

• com.imecatro.demosales.datasource: Includes the main Room database definition (AppRoomDatabase) that aggregates all DAOs from the data modules.

• com.imecatro.demosales.navigation: Contains the navigation graphs and destination definitions for each feature (Products, Sales, Clients), facilitating a decoupled navigation system.

• MainActivity.kt: The single activity of the application, responsible for setting up the UI and navigation.

• PuntroSalesDemoApp.kt: The Application class, annotated with @HiltAndroidApp to initialize Hilt.
