Overview

This project is a Flutter application that uses Riverpod for state management and dependency injection, Clean Architecture for the project structure, Fake Store API for data retrieval, and Dio for network communication.

Requirements

To run this project, you need to have the following software installed on your machine:

• Flutter (3.7.12 - Stable)
• Dart ('>=2.19.6 <3.0.0')

Installation

1. Clone the repository to your local machine.
2. Open the project in your preferred IDE.
3. Run flutter pub get to install the required dependencies.

Usage

You can run the project on either an emulator or a physical device using the command flutter run.

Project Structure

The project uses Clean Architecture, which separates the code into layers: Presentation, Domain, and Data. Each layer has its own responsibility and is independent of the other layers.

The project structure is as follows:

    │   ├── core/

Dependencies

• flutter_riverpod: 2.3.6
• dio: 5.1.1
• dartz: 0.10.1

Feature

• Fetching all products and categories
• Filtering fetched products by category locally
• Fetching product details and caching the response
• Improving performance of ListView by using overrideWithValue and passing const widget
• Navigation using GoRouter

Dependency Injection, State Management & Caching

The project uses Riverpod for both state management and dependency injection. It allows for easy management of dependencies and makes it easier to test the code. By combining FutureProvider.autoDispose with keepAlive caching is also acheieved.

Network Communication

The project uses Dio for network communication, which is a powerful HTTP client for Dart. It makes it easy to make network requests and handle responses.

Data Retrieval

The project uses the Fake Store API for data retrieval. This is a fake e-commerce API that provides product data that can be used for testing and demonstration purposes.

Conclusion

This project is an example of how to use Flutter, Riverpod, Clean Architecture, Fake Store API, and Dio together to create a robust and maintainable application.
