Bloc vs. GetX for Large-Scale Flutter Apps: Which One is Better?

Did you know why Bloc is mostly used in Large-Scale Apps and GetX is not recommended? Let’s find the deep-dive difference between Bloc vs. GetX and which one is better for Large-Scale Flutter Apps. Bloc and GetX are two popular state management libraries for Flutter apps. However, Bloc is generally considered to be a better choice for large-scale apps, while GetX is better suited for smaller and simpler apps.

In this blog post, we will discuss the reasons why Bloc is used in large-scale apps, but GetX is not recommended. We will also provide some guidance on which library is best for your Flutter project.

Bloc

Bloc is a state management Flutter library that is known for its scalability, testability, and predictability. It is based on the principle of unidirectional data flow, which means that the state of the app is always updated in a predictable way. This makes it easier to debug and maintain large and complex apps.

GetX

GetX is a newer state management flutter library known for its simplicity, flexibility, performance, and ease of use. It uses a reactive programming approach, which can make it easier to develop dynamic and responsive user interfaces. Also, GetX is a good choice for small to medium-sized apps with simple state management needs.

Why Bloc Used in Large-Scale Apps

Imagine that you are developing a social media app. This app will have a number of different features, such as a news feed, a messaging system, and a profile page. Each of these features will have its own state, and you will need to manage that state effectively. For example, the news feed state will need to be updated whenever a new post is added.

It would be very difficult to manage all of this state manually. You would need to write a lot of code to keep track of all of the different states and their changes.

This is where the Bloc comes in place. Bloc provides a way to manage the state in a scalable and predictable way. Using Bloc you can create a separate Bloc class for each feature of your app. Each Bloc class would be responsible for managing the state of that feature.

For example, you would create a NewsFeedBloc class to manage the state of the news feed. This class would have a stream of state changes, which you could listen to from your widgets. When a new post is added to the news feed, the NewsFeedBloc would emit a new state change. This would cause your widgets to rebuild, and the new post would be displayed.

Benefits of Using Bloc In Large-Scale App

Here are some of the benefits of using Bloc in a large-scale app:

• Scalability

  You can easily add new features to your app without having to worry about how to manage their state because the bloc is designed to be scalable.

• Predictability

  Bloc is a predictable state management library. This means that it is easy to reason about how your app will behave, even when it is complex.

• Testability

  It is easy to test the business logic of your app with bloc because it is decoupled from the UI.

• Maintainability

  You can make your code more maintainable with Bloc because it is organized and easy to understand.

• Community Support

  Due to the large and active community of Bloc, there are plenty of resources available to help you learn and use the library. There are also a number of libraries and plugins available that work with Bloc.

Reasons Why GetX is Not Recommended For Large-Scale Apps

To understand why GetX is not recommended for large-scale apps, Imagine you develop a large-scale e-commerce app. This app will have a number of different features, such as a product catalog, a shopping cart, and a checkout process.

Each of these features will have its own state, and you will need to manage that state effectively. For example, the shopping cart state updates whenever you add or remove the product.

If you use GetX to manage the state in your app, you need to use a number of features, such as dependency injection and route management. However, these features can make your code more complex and difficult to maintain, especially in a large-scale app.

GetX is a state management library that has strong opinions about how state management should be done. This means that it has a specific way of doing things, which may not work for everyone. This is especially true for complex projects with specific requirements.

The main reason why GetX is not recommended for large-scale apps is that it is not as scalable or testable as Bloc.

Reasons

• Scalability

  The new library GetX has not been as well-tested as Bloc for large-scale apps. Additionally, GetX is more opinionated than Bloc, and it may not be a good fit for all projects.

• Testability

  Due to GetX is not as testable as Bloc, it is more tightly coupled with the UI. This makes it more difficult to test the business logic of your app in isolation.

• Community Support

  Same level of community supported by GetX as Bloc. This means that there are fewer resources available to help you learn and use the library.

A newer library GetX released after Bloc does not have the same level of scalability, testability, or community support. Additionally, GetX is more opinionated than Bloc, and it may not be a good fit for all projects.

However, GetX is easier to learn and use than Bloc, and it can be a good choice for smaller and simpler apps. It also offers a number of features that can be useful, such as dependency injection and route management.

Bloc vs. GetX: Which Library is Best For Your Flutter Project?

If you are developing a large-scale app or an app with complex state management requirements, then Bloc is the better choice. It is more scalable, testable, and has better community support than GetX.

If you are developing a smaller and simpler app, then GetX can be a good choice. It is easier to learn and use, and it offers a number of features that can be useful.

Difference Between Bloc vs. GetX State Management Flutter Libraries

Here is a more detailed comparison of the two libraries:

Ultimately, the best way to decide which library to use is to consider the specific needs of your project.

Conclusion

Both Bloc and GetX are good state management libraries for Flutter apps. However, GetX is better suited for smaller and simpler apps, while Bloc is better suited for large-scale apps. If you are unsure which library to use, I recommend starting with Bloc. It is a more mature and scalable library, and it has better community support. Once you have a good understanding of Bloc, you can then decide if GetX is a better fit for your specific project.
