Business Logic Component (BLoC) design pattern Training Course

Introduction to State Management

• Exploring the concept of state in Flutter applications
• A survey of available Flutter state management approaches

• Handling errors and state transitions

Integrating BLoCs with Flutter Widgets

• Integrating BLoCs into the widget tree
• Utilising BlocProvider, BlocBuilder, BlocListener, and BlocConsumer
• Optimising widget rebuilds for efficiency
• Interacting with BuildContext

Navigation and BLoC Communication

• Transferring data between screens
• Facilitating communication between multiple BLoCs
• Overseeing shared application state
• Orchestrating 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

• Writing unit tests for BLoCs and Cubits
• Conducting widget tests with BLoC
• Troubleshooting state transitions
• Logging and resolving common issues

Hands-on Application Development
