Business Logic Component (BLoC) design pattern Training Course

Introduction to State Management

• Grasping the concept of state within Flutter applications
• Surveying various state management strategies in Flutter
• Determining the optimal scenarios for employing the BLoC pattern
• The advantages of decoupling business logic from the user interface

Exploring the BLoC Pattern

• Fundamental BLoC principles
• Working with events, states, and streams
• Basics of reactive programming
• The lifecycle of a BLoC

Architecting with BLoC

• Structuring Flutter applications using the BLoC framework
• Isolating presentation, business logic, and data layers
• Structuring projects for long-term maintainability
• Incorporating clean architecture principles

Building and Managing BLoCs

• Developing custom BLoCs and Cubits
• Controlling application state
• Processing asynchronous operations
• Managing error handling and state transitions

Connecting BLoCs with Flutter Widgets

• Integrating BLoCs into the widget tree
• Utilizing BlocProvider, BlocBuilder, BlocListener, and BlocConsumer
• Optimizing widget rebuilds for performance
• Interacting with BuildContext

Navigation and Inter-BLoC Communication

• Transferring data between different screens
• Facilitating communication among multiple BLoCs
• Oversight of shared application state
• Orchestrating complex user workflows

Data Persistence and Local Storage

• Connecting local storage solutions with BLoC
• Overseeing cached application data
• Aligning local and remote data sources
• Adopting best practices for persistent state management

Testing and Debugging

• Conducting unit tests for BLoCs and Cubits
• Performing widget tests using BLoC
• Diagnosing state transition issues
• Logging and resolving common technical challenges

Practical Application Development

• Developing a full-scale Flutter application using the BLoC pattern
• Implementing navigation and state control mechanisms
• Executing tests and debugging the application
• Evaluating best practices and planning subsequent steps
