Introduction

Dart is a modern, open-source programming language developed by Google. It's known for its speed, efficiency, and ease of learning. Dart can be used for web, mobile, server, and desktop applications.

This tutorial aims to provide a comprehensive introduction to Dart, covering the basics and gradually progressing to more advanced concepts.

Prerequisites

Before starting this tutorial, make sure you have the following prerequisites:

• Basic understanding of programming concepts
• Code editor (e.g., Visual Studio Code, IntelliJ IDEA)
• Dart SDK installed on your system

If you haven't installed Dart SDK yet, you can download it from the official Dart website.

Getting Started

To get started with Dart, follow these steps:

1. Install Dart SDK on your system.
2. Set up your development environment by configuring a code editor (e.g., Visual Studio Code) for Dart.
3. Clone this repository`

Topics Covered

This tutorial covers the following topics:

• Dart basics
• Variables and data types
• Control flow (if-else, switch, loops)
• Functions and error handling

Feel free to explore the code and documentation for each topic in detail.

Dart Basics

1. Hello, Dart!

The traditional "Hello, World!" program in Dart:

dart
void main() {
print('Hello, Dart!');
}


2. Variables and Data Types

In Dart, you can declare variables using var, int, double, String, bool, and more. Example:
dart
void main() {
var name = 'John Doe'; // String
int age = 30; // Integer
double height = 6.2; // Double
bool isStudent = true; // Boolean
}

Dart is a statically typed language, meaning that variable types are known at compile time. However, you can use var to have Dart infer the type.

3. Control Flow

Dart supports common control flow structures like if, else, switch, and loops (for, while, do-while). Example:

`dart
void main() {
var age = 30;

if (age < 18) {
print('You are a minor.');
} else if (age >= 18 && age < 60) {
print('You are an adult.');
} else {
print('You are a senior citizen.');
}
}
`

4. Functions

Creating a simple function in Dart:

`dart
void main() {
print(greet('John Doe'));
}

String greet(String name) {
  return 'Hello, $name!';
}

`
Dart also supports anonymous functions (functions without a name) and arrow functions (functions with a single expression). Example:

`dart
void main() {
var numbers = [1, 2, 3, 4, 5];

// Anonymous function
numbers.forEach((number) {
print(number);
});

// Arrow function
numbers.forEach((number) => print(number));
}
`
