Business Logic Component (BLoC) design pattern Training Course

Introduction to State Management

• Comprehending state within Flutter applications.
• An overview of various Flutter state management strategies.
• Identifying when and why to adopt the BLoC pattern.
• The advantages of decoupling business logic from the user interface.

Understanding the BLoC Pattern

• Foundational BLoC concepts.
• The interplay of events, states, and streams.
• Essential principles of reactive programming.
• The lifecycle of a BLoC.

Designing BLoC Architecture

• Structuring Flutter applications effectively using BLoC.
• Clearly distinguishing between presentation, business logic, and data layers.
• Organising project structures for long-term maintainability.
• Incorporating clean architecture principles.

Creating and Managing BLoCs

• Building custom BLoCs and Cubits.
• Overseeing application state efficiently.
• Managing asynchronous operations.
• Implementing robust error handling and state transitions.

Integrating BLoCs with Flutter Widgets

• Injecting BLoCs into the widget hierarchy.
• Utilising BlocProvider, BlocBuilder, BlocListener, and BlocConsumer.
• Optimising widget rebuilds for performance.
• Working effectively with BuildContext.

Navigation and BLoC Communication

• Transferring data seamlessly between screens.
• Facilitating communication between multiple BLoCs.
• Managing shared application state.
• Coordinating complex user workflows.

Data Persistence and Local Storage

• Connecting local storage solutions with BLoC.
• Managing cached application data.
• Synchronising local and remote data sources.
• Adhering to best practices for persistent state.

Testing and Debugging

• Performing unit tests on BLoCs and Cubits.
• Conducting widget tests using BLoC.
• Debugging complex state transitions.
• Logging insights and troubleshooting common issues.

Hands-on Application Development

• Developing a complete Flutter application utilising the BLoC pattern.
• Implementing comprehensive navigation and state management.
• Testing and debugging the finished application.
• Reviewing best practices and outlining next steps.
