Welcome to Episode 2! Today we're building the foundation of our Sudoku game by creating robust data models. Learn how to structure data properly, implement JSON serialization, and build reusable models that power the entire app.

🔥 What's Covered in This Episode:
✅ Create SudokuPuzzle model (puzzle structure)
✅ Build GameState model (game progress tracking)
✅ Implement GameMove class (undo functionality)
✅ JSON serialization with toJson()
✅ JSON deserialization with fromJson()
✅ Factory constructors for object creation
✅ Deep copying arrays to prevent mutations
✅ Understanding immutable vs mutable data

📋 Homework Challenge:
Before Episode 3, try to:
1. Add a 'playerName' property to GameState
2. Include it in toJson() and fromJson()
3. Understand why we convert bool to int for JSON
4. Draw a diagram of the data structure
5. Explain to someone why we need deep copying

🎯 Next Episode Preview:
In Episode 3, we'll create our Puzzle Library! You'll learn how to:
Store multiple Sudoku puzzles
Organize puzzles by difficulty
Implement puzzle selection logic
Use dart:math for random selection
Structure large data efficiently
