• meta - Annotations package
• Json Serializable - Provides Dart Build System builders for handling JSON.
• Shimmer - A package provides an easy way to add shimmer effect in Flutter project

Introduction Clean Architecture

The idea is simple: clean architecture stands for a group of practices that produce systems that are:

• Independent of Frameworks.
• Testable.
• Independent of UI.
• Independent of Database.
• Independent of any external agency.

It is not a must to use only 4 circles (as you can see in the picture), because they are only schematic but we should take into consideration the Dependency Rule: source code dependencies can only point inwards and nothing in an inner circle can know anything at all about something in an outer circle.

Here is some vocabulary that is relevant for getting familiar and understanding this approach in a better way:

• Entities: These are the business objects of the application.
• Use Cases: These use cases orchestrate the flow of data to and from the entities. Are also called Interactors.
• Interface Adapters: This set of adapters convert data from the format most convenient for the use cases and entities. Presenters and Controllers belong here.
• Frameworks and Drivers: This is where all the details go: UI, tools, frameworks, etc.

Architectural Approach

Architectural Reactive Approach

Clean Architecture that will we use

Introduction of Bloc

Its a state management system for Flutter recommended by Google developers. It helps in managing state and make access to data from a central place in your project.
