Introduction to Flutter and Software Design

1. What is Flutter?

   • Overview of Flutter and its architecture.
   • Benefits of Flutter for modern app development.
   • The role of Flutter in cross-platform design.

2. Importance of Software Design in Flutter

   • Maintainability, scalability, and reusability.
   • Design principles and patterns for clean code.

Design Principles in Flutter

1. Separation of Concerns

   • Layers in Flutter: UI, Logic, and Data.
   • Using Provider, Riverpod, and Bloc for state management.

2. Single Responsibility Principle

   • Breaking down widgets and components.
   • Modularizing code for clarity.

3. Declarative UI Design

   • Advantages of Flutter's widget tree approach.
   • Managing widget lifecycle effectively.

Architectural Patterns in Flutter

1. Model-View-Controller (MVC)

   • Example: Building a basic CRUD app with MVC.

2. Model-View-ViewModel (MVVM)

   • Integrating MVVM with state management tools.

3. Business Logic Component (BLoC)

   • Understanding Streams and Sinks.
   • Event-driven architecture with BLoC.

4. Clean Architecture

   • Layers: Presentation, Domain, and Data.
   • Dependency Injection and Use Cases.

UI/UX Design Best Practices

1. Responsive Design

   • LayoutBuilder and MediaQuery for adaptive UI.
   • Using Flutter’s responsive frameworks (e.g., flutter_screenutil).

2. Custom Widgets

   • Building reusable components.
   • Extending Material and Cupertino widgets.

3. Accessibility

   • Adding semantics and supporting screen readers.
   • Handling gestures and keyboard navigation.

4. Animations and Motion Design

   • TweenAnimationBuilder, Hero Animations, and Custom Animations.
   • Using Rive for advanced animations.

State Management in Flutter

1. Inheritable Widgets

   • Basic examples of scoped state sharing.

2. Provider and Riverpod

   • When and how to use these popular tools.

3. BLoC and Cubit

   • Event-driven state management.
   • Practical use cases in enterprise applications.

Database Design and Integration

1. Choosing a Database

   • SQLite (sqflite) vs. NoSQL (Hive, Firebase).

2. Integrating Databases with Flutter

   • CRUD operations and syncing data.

3. Offline-first Design

   • Caching strategies and syncing on reconnection.

Testing and Debugging in Flutter

1. Unit Testing

   • Writing tests for widgets, models, and utilities.

2. Integration Testing

   • Automating app workflows with integration tests.

3. Debugging Tools

   • Flutter DevTools and logging with Logger.

Deployment and Optimization

1. Optimizing Performance

   • Reducing widget rebuilds.
   • Best practices for network calls.

2. Building for Multiple Platforms

   • Adapting UI and interactions for Android, iOS, and web.

3. Continuous Integration/Continuous Deployment (CI/CD)

   • Setting up CI/CD pipelines with tools like GitHub Actions and Codemagic.
