Explanation:

• main.dart:

  • Entry point of the application.

• app/:

  • Contains all application-specific logic.

• app/screens/:

  • Contains individual screens of the application.
  • Each screen represents a specific UI component of the app.

• app/widgets/:

  • Reusable UI components/widgets used across multiple screens.

• app/models/:

  • Data models representing entities in the application.
  • Models are used to structure and manage data within the app.

• app/providers/:

  • Riverpod providers for managing the application state.
  • Provides data to different parts of the application.

• app/services/:

  • Services for handling external operations such as network requests, database interactions, etc.
  • Encapsulates functionality related to specific services.

• app/main_app.dart:

  • Initializes the application, sets up Riverpod providers, and defines MaterialApp.

• theme/:

  • Contains files related to the theme of the application.
  • Defines the visual appearance of the app.

• utils/:

  • Contains utility/helper functions and constants used throughout the application.
  • Encapsulates commonly used functionalities and constants.

Usage:

• Screens: Add new screens under app/screens/ directory. Each screen should be a separate Dart file representing a specific UI component.

• Widgets: Create reusable UI components under app/widgets/ directory. These components can be shared and reused across multiple screens.

• Models: Define data models under app/models/ directory. These models represent entities within the application and help manage data.

• Providers: Implement Riverpod providers under app/providers/ directory. These providers manage the application state and provide data to different parts of the application.

• Services: Develop external services under app/services/ directory. These services handle operations such as authentication, data fetching, etc., and encapsulate related functionality.

• Main App: Configure the main application setup in app/main_app.dart. Set up Riverpod providers, define MaterialApp, and initialize the app.

• Theme: Define the visual theme of the application in theme/app_theme.dart. Customize colors, typography, and other visual aspects of the app.

• Utilities: Create utility/helper functions and constants in utils/ directory. These utilities encapsulate commonly used functionalities and constants used throughout the application.
