Learn a lot in flutter bloc
What you will learn
Learn two state management methods provided by Flutter Bloc called Cubit and Bloc
Create apps to understand flutter bloc concept
BlocProvider, BlocListener, BlocConsumer
MultiBlocProvider
Description
Flutter bloc is one of the state management for Flutter applications. You can use it to handle all the possible states of your application in an easy way.
Flutter bloc is simple to use because you and your team are going to understand the concept quickly, no matter what is your level, this library has very good documentation with tons of examples and also, is one of the most used in the flutter community, so if you have any question or problem you probably are going to find the solution with a simple search on the internet.
Is powerful because is going to help you to create all kinds of applications, you can create applications for learning purposes for example, and also you can create complex applications in a production environment and flutter bloc is valid in both cases.
Another important aspect of this library is that you could test your bloc logic in an easy way.
To understand how bloc works, we need to know what are events and states.
- Events: events are an applicationβs inputs (like button_press to load images, text inputs, or any other user input that our app may hope to receive).
- States: States are simply the applicationβs state, which can be changed in response to the event received.
Bloc manages these events and states, i.e., it takes a stream of Events and transforms them into a stream of States as output.
Content
- Course Overview
- Master the art of state management in the modern Flutter ecosystem using the BLoC (Business Logic Component) architectural pattern.
- Understand the transition from basic stateful widgets to a decoupled architecture where UI and logic exist in separate layers.
- Explore the fundamental differences between Cubit and Bloc, learning exactly when to use each for optimal app performance.
- Learn to structure large-scale applications using Clean Architecture principles to ensure code maintainability and scalability.
- Deep dive into Event-Driven Programming and how to handle complex user interactions through structured event flows.
- Requirements / Prerequisites
- A solid foundational understanding of the Dart programming language, specifically asynchronous programming (Futures and Streams).
- Basic experience building simple Flutter layouts and working with the Widget Tree.
- A computer with the Flutter SDK installed and configured for development.
- Familiarity with an IDE such as Visual Studio Code or Android Studio.
- A desire to move beyond “spaghetti code” toward professional-grade software engineering.
- Skills Covered / Tools Used
- Comprehensive usage of the flutter_bloc and bloc packages for state handling.
- Implementation of the Repository Pattern to bridge the gap between data sources and business logic.
- Utilization of Equatable to simplify object comparisons and prevent redundant UI repaints.
- Integration of Hydrated Bloc to provide seamless state persistence across application restarts.
- Advanced Dependency Injection techniques using the RepositoryProvider and BlocProvider widgets.
- Mastering Reactive Programming concepts using Dart Streams to listen for real-time data changes.
- Benefits / Outcomes
- Gain the ability to write highly testable code by isolating logic from the visual presentation layer.
- Develop a production-ready mindset that aligns with the standards of top-tier tech companies and agencies.
- Boost application performance by utilizing fine-grained rebuilds through BlocBuilder and BlocSelector.
- Create a robust portfolio project that demonstrates your expertise in handling complex global states.
- Prepare yourself for senior Flutter developer roles by mastering the industry’s most popular state management solution.
- PROS
- Modern Curriculum: Content is specifically tailored for the 2024 Flutter landscape and Dart’s latest features.
- Architectural Clarity: Focuses on building a logical mental model rather than just memorizing syntax.
- Scalability: Teaches techniques that work for both small hobby projects and massive enterprise applications.
- CONS
- Learning Curve: The initial shift to reactive programming and boilerplate setup may feel challenging for developers transitioning from simpler state management methods.
