Freshflow assessment

TLDR;

How to run

Assuming you have Flutter installed on your env.

2 choices:

• Via your preferred IDE, example for example Android Studio:
  • create a Flutter run configuration with lib/presentation/main.dart entrypoint.
  • Click on run.
• Via CLI:
  • run flutter pub get
  • run flutter packages pub run build_runner build --delete-conflicting-outputs
  • run flutter run lib/presentation/main.dart

The context

This project is an assessment asked by Freshflow during the interview process of a Senior Flutter developer position.

Task
Create a simple Flutter app that displays a simple shopping cart stored online

The project

Choices

Architecture

I have chosen the Clean Architecture (more in Uncle Bob definition), layering the application in 3 different layers (data, domain, and presentation).

Some benefits of doing so includes: Framework independence, UI independence, Separation of concern, Highly testable.

Technologies

I notably used the following lib and design pattern:

• MVVM for the presentation layer with BloC.
• GetIt for dependencies injection.
• Stream for all flows.
• Freezed for Sealed Class and serialization.
• Logger.

Limitations

Due to the very limited time, here is the improvement the app need:

• No error handling.
• Not working without internet.
• No logging functionality (hardcoded).
• No tracking data.
• No code coverage.

Goal of the assessment

This code is a base to show how I work and to open a dialogue. With more time, all asked point could be cleanly answered.

I would be happy to speak about the solutions I would implement.
