Business Logic Component (BLoC) design pattern Training Course

Foundations of State Management

• Analyzing state within Flutter applications.
• Surveying various Flutter state management methodologies.
• Evaluating the optimal times and reasons for adopting the BLoC pattern.
• Recognizing the advantages of isolating business logic from the UI.

Mastering the BLoC Pattern

• Exploring central BLoC principles.
• Examining events, states, and data streams.
• Reviewing the basics of reactive programming.
• Tracing the lifecycle of a BLoC instance.

Architecting with BLoC

• Structuring Flutter applications with BLoC in mind.
• Decoupling presentation, business logic, and data layers.
• Structuring projects for long-term maintainability.
• Implementing clean architecture principles.

Building and Controlling BLoCs

• Oversight of application state.
• Processing asynchronous tasks.
• Managing error states and state transitions.

Connecting BLoCs with Flutter Widgets

• Integrating BLoCs into the widget hierarchy.
• Utilizing BlocProvider, BlocBuilder, BlocListener, and BlocConsumer.
• Optimizing widget rebuilds for performance.
• Utilizing BuildContext effectively.

Navigation and Inter-BLoC Communication

• Transferring data across different screens.
• Facilitating communication between multiple BLoC instances.
• Oversight of shared application state.
• Coordinating complex user journeys.

Persistence and Local Data Storage

• Connecting local storage solutions with BLoC.
• Managing cached data within the application.
• Synchronizing local and remote data sources.
• Adopting best practices for persistent state management.

Verification and Debugging

• Conducting unit tests for BLoCs and Cubits.
• Performing widget tests integrated with BLoC.
• Tracing and debugging state transitions.
• Logging activity and resolving common technical issues.

Practical Application Construction

• Developing a complete Flutter application utilizing the BLoC pattern.
• Implementing robust navigation and state control.
• Testing and debugging the finished product.
• Reviewing key best practices and future development steps.
