Welcome to the Full Stack Flutter App Development Series! In this video, we’re diving into an essential skill for every developer—how to add comments in Dart. Whether you're new to Dart or enhancing your app development skills, knowing how to properly use comments will help keep your code organized, readable, and maintainable.

🧠 What You’ll Learn
In this second video of the series, we’ll cover everything you need to know about commenting in Dart, including:

Single-line comments – Great for brief explanations or notes about specific lines of code.
Multi-line comments – Ideal for longer descriptions or blocking out entire sections of code.
Documentation comments – Essential for creating structured comments that help other developers understand your classes, functions, and code logic.
🔍 Why Comments Matter in Coding
As your codebase grows, so does the need for clear documentation. Good comments can:


📌 Be sure to watch our previous video on Dart Basics to get the most out of this series. And if you find this tutorial helpful, don’t forget to like, share, and comment to let us know what you think or any specific topics you’d like us to cover.

Happy coding, and let’s make great apps together!

Here's a simple example that covers the basics of Object-Oriented Programming (OOP) in Dart:

void main() {
// 1. Introduction to Object-Oriented Programming (OOP)
// What is OOP?
// Key principles: Encapsulation, Abstraction, Inheritance, and Polymorphism
// 2. Classes and Objects
// Defining a class
// Creating objects
// Fields, methods, and properties
// 3. Constructors
// Default constructors
// Named constructors
// Factory constructors
// Redirecting constructors
// Constant constructors
// 4. Encapsulation
// Private and public access (using underscores)
// Getters and setters
// Using encapsulation to restrict access
// 5. Inheritance
// Extending classes with extends
// Overriding methods and fields
// The super keyword
// The Object class and inheritance hierarchy
// 6. Mixins
// What are mixins?
// Using the with keyword
// Benefits and limitations of mixins
// 7. Interfaces
// Using classes as interfaces
// Implementing multiple interfaces with implements
// Differences between extends, with, and implements
// 8. Polymorphism
// Method overriding and runtime polymorphism
// Upcasting and downcasting
// 9. Abstract Classes and Methods
// Defining and using abstract classes
// Abstract methods and overriding them in derived classes
// Difference between abstract classes and interfaces
// 10. Static Members and Methods
// Defining static fields and methods
// Accessing static members without creating an instance
// Use cases for static members
// 11. Generics
// Using generics with classes and methods
// Type safety with generics
// Benefits of using generics in Dart
// 12. Object-Oriented Design Patterns
// Common patterns like Singleton, Factory, Observer, etc.
// Using patterns effectively in Dart
// 13. Extension Methods
// Adding functionality to existing classes
// Using extension keyword
// Limitations and best practices
// 14. Type System and Null Safety
// Understanding type safety and null safety in Dart
// Nullable and non-nullable types (? and !)
// Late initialization with late keyword
// 15. Overloading Operators
// Customizing operator behavior for classes
// Using operator keyword to define operators like +, ==, etc.
// 16. Memory Management
// How Dart manages memory for objects
// The garbage collection process
// Best practices for optimizing memory in OOP
