A2SV Mobile Development Assessment

Welcome to the Flutter Developer Assessment! This task evaluates your ability to work with APIs, manage state, and implement core app functionality. You’ll have 2 hours to complete the tasks below.

Task Overview

You’ll build a shopping cart app using the FakeStoreAPI. The test has three main components: API Integration, Cart Functionality, UI/UX enhancements and add a new feature which is creating favorites section.

The starter code includes:

ApiService (with the method to be implemented).

CartProvider (partially implemented).

Basic UI for product listing and cart.

Favorites Screen

Setup Instructions

Fork the repository and clone it to your local machine.

Tasks

Fix and Enhance ApiService

The ApiService class has some issues. Your tasks are:

Fix fetchProducts: Ensure it fetches and parses products correctly.

Error Handling: Add proper error handling for network failures.

Deliverables:

A fully functional ApiService class.

A fully functional cart with all features listed above.
Clean and reusable code.

Favorites Screen

Add a new screen to the app that displays a list of favorite products for the user.

Error Handling: Are edge cases (e.g., network failures) handled gracefully?

UI/UX : Is the app intuitive and visually appealing?

Testing: Are the tests comprehensive

Submission Guidelines
