It requires:

• Handling login of a user. Store login credentials locally so that the user is automatically logged in when opening the app in the future.

• Requesting data with http package. The response can return a success object, multiple choices, an error object or throw exception. Therefore it's needed to handle all these scenarios.

• Showing the data or the errors to the user.

Getting Started

• clone the repo
• run pub get for dependencies
• run build_runner for code generation

Login User credentials (can be found in the file lib/core/mocks/auth_client.dart):

• email: [email protected]
• password: 1234qwer

Coding methodology

Main packages used: dependency injection (get_it, injectable), reactive programming (rxdart, flutter_bloc), functional programming (dartz), freezed.

The project has been structured following the clean code architecture described by uncle Bob.

Therefere the app is structured with the following directories and files:

• lib/
  • core/
  • features/
  • di_config.dart
  • main.dart

Core

The core folder contains utility services that can be used throughout all the features, such as input fields validation or errors.

Features

The features folder contains the features. Each feature is structured in the following way:

• data
• domain
• presentation

The data layer is the one that interacts with the outside world in case of remote data source or with the local storage in case of local data source.

The domain layer is made of pure dart code and contains the entities that characterize the core of the feature

The presentation layer contains the code for showing the data to the users throught the UI and manages the state of the UI
