Use BLoC for Every Screen

Using BLoC for every screen is one of the best practices we can use when building an application. In this lesson, we’ll discuss the benefits of using BLoC for every screen.

Benefits of using BLoC for every screen

• Simplifying complex UI logic: UI logic can become complex when dealing with user input, responding to network requests, and updating data. BLoC helps to simplify UI logic by separating the business logic from the presentation logic. This makes it easier to understand and maintain the codebase.

• Unit testing: By utilizing the BLoC design pattern on every screen, we can easily isolate and test the functionality of each screen independently. This approach can help to improve the overall maintainability and scalability of the application.

How to use BLoC for every screen

Every time we create a screen that has some state, we do the following:

1. Create a bloc folder in the same folder as your screen.

2. Implement the Bloc/Cubit.

3. Provide the BLoC to the screen using BlocProvider.

4. Use the BLoC for all business logic that needs to be done on the screen.
