Business Logic Component (BLoC) design pattern Training Course

Introduction to State Management

• Conceptualizing state within Flutter applications
• A survey of available state management strategies in Flutter
• Identifying appropriate scenarios for adopting the BLoC pattern
• Advantages of decoupling business logic from the user interface

Exploring the BLoC Pattern

• Foundational BLoC principles
• The roles of events, states, and streams
• Core concepts of reactive programming
• The lifecycle of a BLoC

Architecting with BLoC

• Structuring Flutter applications through BLoC

• Processing asynchronous tasks
• Managing errors and state transitions

Connecting BLoCs with Flutter Widgets

• Injecting BLoCs into the widget hierarchy
• Leveraging BlocProvider, BlocBuilder, BlocListener, and BlocConsumer
• Optimizing widget rebuilds for performance
• Interacting with BuildContext

Navigation and Inter-BLoC Communication

• Transferring data across different screens
• Facilitating communication among multiple BLoCs
• Overseeing shared application state
• Orchestrating intricate user workflows

Data Persistence and Local Storage

• Integrating local storage solutions with BLoC
• Managing cached data within the application
• Aligning local data with remote sources
• Best practices for managing persistent state

Testing and Debugging Strategies

• Unit testing BLoCs and Cubits
• Performing widget tests with BLoC
• Tracing state transitions for debugging
• Utilizing logging to troubleshoot common issues

Practical Application Development

• Developing a comprehensive Flutter application using the BLoC pattern
• Implementing navigation and state control
• Conducting tests and debugging the project
