In this comprehensive lecture, we explore how to create dynamic user interfaces with animations, implement navigation between screens, and persist user data locally. You'll learn to build a complete Login & Signup app with state management, local storage, and smooth screen transitions using real-world development patterns.
🔹 Topics Covered:
• Implicit Animations:
o Easy animations with AnimatedContainer, AnimatedAlign, AnimatedOpacity, AnimatedPadding, etc.
o Automatically animating property changes
o Live coding: Building animated UI components
• Explicit Animations:
o Using AnimationController for manual animation control
o Managing animation lifecycles in StatefulWidgets
o When to choose explicit vs. implicit animations
• Multi-Screen Authentication App:
o Separate Login, Signup, and Home pages
o Navigation between screens using Navigator and MaterialPageRoute
o Passing data between pages/screens
• Local Data Persistence:
o Using the localstorage package for key-value storage
o Serializing custom objects (UserModel) to JSON with manual serialization
o Saving and retrieving user credentials between app sessions
o Fixing web port issues with web_dev_config.yaml
• State Management Review:
o setState() for ephemeral state
o Provider for app-wide state (used in our auth app)
o Introduction to Riverpod and BLoC for larger applications
• Data Storage Options:
o Local key-value storage (shared_preferences, localstorage)
o Secure storage with flutter_secure_storage
o Local databases (SQLite) and cloud solutions (Firebase, REST APIs)
🔹 Hands-On Projects:
• Login & Signup App: Full authentication flow with data persistence
• UserModel Class: Custom class with manual JSON serialization
• Animated UI Components: Building visually engaging interfaces
• Multi-Page Navigation: Implementing professional screen transitions
🔹 Packages Used:
• provider: ^6.1.1 – State management
• localstorage: ^5.0.0 – Local key-value storage
• dart:convert – JSON serialization
