This application uses BLoC. Providing you are using Clean Architecture in the intended manner, it ultimately doesn't matter what state management solution/framework you choose as you can easily swap one out for the other as you'll find below.

There are a number of Flutter tutorials out there that illustrate how to build an application with different state management solutions such as BLoC, GetX, Riverpod etc. However most are incomplete, they do not show how to integrate networking and make API calls or how tests can be written. In short, they do not provide an overall solution for clean architecture implementation. This project aims to give an insight into how you would create a production-level application that is scalable, testable and written with clean code.
- How to structure your application so that everything is modularised and discrete.
- How to write tests for every module of your application.
- How to structure your architecture in such a way that you can replace modules with different tools/libraries as you see fit. E.g. Replacing your
BLoCstate management with something likeRiverpod.
There are certainly a number of ways that you can implementation your application such that you abide by the right design principles (SOLID, DRY, YAGNI etc.). However, there is no one approach that works better than the others. There is only those that are more modularised. Hence, the approach you should take depends on the project, its requirements and its constraints. For example, if you needed to create an MVP in a short amount of time you certainly wouldn't want to implement an architecture that conformed to TDD and was made of discrete components. You would want to use something that required little boiler-plate code and that should be developed quickly.
With that said, this approach here is not meant for MVP applications but rather for large-scale applications that require unit testing and components that aren't coupled together. I discuss in detail what the approach entails and how and why modules are organised and created in the fashion they are. You can read about it at the README here.
To get a local copy up and running follow these simple example steps.
- Follow the Flutter guide on Get Started to install the Flutter SDK on your machine. NOTE this project is built with Flutter version 2.8.0.

- Clone the repo
git clone https://github.com/ajvelo/Flutter-News.git
- Install pub packages
flutter pub get
- Create a file in
lib/core/calledconstants.dartclass Constants { static const apiKey = "YOUR-API-KEY"; }
