• User Interface Design (console)

3. Basic Dart Concepts (learn_01.dart)

Fundamental Dart programming concepts including:

• Variables and data types
• Null safety
• Collections and loops
• Functions and classes
• String interpolation

Key Concepts Practiced:

• Basic syntax
• Type system
• Collections manipulation
• Function definitions
• Class constructors

4. Asynchronous Programming (learn_02_async.dart)

Advanced async concepts for Flutter preparation:

• Future and async/await
• Error handling with try-catch
• Stream controllers
• Parallel operations
• API simulation patterns

5. Flutter-Ready Patterns (learn_03_flutter_patterns.dart)

Widget-like patterns and Flutter development preparation:

• Widget-style classes
• Builder patterns
• State management concepts
• Callback functions
• Generic types

🎯 Learning Objectives

This repository demonstrates my understanding of:

• Dart Language Fundamentals: Syntax, types, null safety
• Object-Oriented Programming: Classes, inheritance, encapsulation
• Asynchronous Programming: Futures, async/await, error handling
• Design Patterns: Builder pattern, service layer architecture
• Code Organization: Separation of concerns, clean architecture
• Real-world Applications: Banking and HR systems

🚀 How to Run

Make sure you have Dart SDK installed:

# Check Dart installation
dart --version

# Run any project
dart run banking_system.dart
dart run employee_system.dart
dart run learn_01.dart
