Flutter Clean Architecture App:

This project demonstrates a flutter app built with a clean architecture & Test Driven Development approach. The goal is to provide a well-structured and maintainable codebase.

Architecture:

Clean Architecture: The application follows the principles of Clean Architecture, separating concerns into distinct layers:

  • Presentation Layer: Handles UI interactions and user input.

  • Domain Layer: Encapsulates business logic and domain rules.

  • Data Layer: Provides data access and persistence.

  • Provider: Project uses the Provider package for state management, simplifying data sharing and UI updates.

  • Dio: For network communication, the Dio package is used, offering a robust and flexible API for making HTTP requests.

  • GetIt: Dependency Injection is handled with the GetIt package, promoting code reusability and testability.

  • Firebase Authentication: The app utilizes Firebase Authentication for user authentication.

Dependencies:

  • flutter: Core Flutter framework.
  • provider: State management and UI updates.
  • dio: Network communication.
  • get_it: Dependency Injection.
  • firebase_core: Firebase initialization.
  • firebase_auth: Firebase Authentication.
  • connectivity_plus: Network connectivity monitoring.
  • google_fonts: Custom fonts.
  • equatable: For simplifying equality checks in data models.
  • dartz: For functional programming concepts and error handling.

Testing:

Integration Tests: Implemented integration tests to validate the login flow, bitcoin transaction details screen, and tezos transaction details screen.

To run the integration tests, use the following command:

flutter drive --driver=test_driver/integration_test.dart --target=integration_test/authentication_test.dart integration_test/bitcoin_transaction_test.dart integration_test/tezos_transaction_test.dart
