Dart Programming Tutorial for Beginners

Are you interested in learning Dart programming? Whether you’re planning to dive into Flutter development or simply want to learn a modern, powerful language—this Dart tutorial is the perfect starting point for beginners.

What is Dart?

Dart is an open-source, general-purpose programming language developed by Google. It is optimized for building fast, modern web and mobile apps. Dart is the language behind Flutter, Google’s popular UI toolkit for cross-platform development.

Easy to learn for JavaScript, Java, or C# developers
Used with Flutter to build Android, iOS, Web, and Desktop apps
Fast, expressive, and safe language

How to Install Dart?

You can install Dart in two ways:

1. Using Flutter SDK (Recommended)

If you’re learning Dart for Flutter:

https://flutter.dev/docs/get-started/install

2. Install Dart SDK Directly:

Go to https://dart.dev/get-dart and follow the setup instructions for your operating system.

Your First Dart Program

Create a new Dart file and name it hello.dart:

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

Run it:

dart hello.dart

Output:

Hello, Dart!

Dart Basics

1. Variables

void main() {
  var name = 'Shri Kant';
  int age = 25;
  double height = 5.9;
  bool isStudent = true;

  print('$name is $age years old.');
}

2. Data Types

int – Integer values
double – Decimal values
String – Text
bool – true or false
List – Arrays
Map – Key-value pairs

3. Functions

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

void main() {
  greet('Shri Kant');
}

4. Conditionals

void main() {
  int marks = 75;

  if (marks >= 60) {
    print('Pass');
  } else {
    print('Fail');
  }
}

5. Loops

void main() {
  for (int i = 1; i <= 5; i++) {
    print('Number: $i');
  }
}

5.1 While Loops

void main() {
  int i = 1;

  while (i <= 5) {
    print('Number: $i');
    i++;  // Increment i by 1
  }
}

6. Using Lists in Dart

Lists in Dart allow you to store multiple values in a single variable. Here’s an example:

void main() {
  List<String> fruits = ['Apple', 'Banana', 'Orange'];

  for (var fruit in fruits) {
    print(fruit);
  }
}

Explanation:

We create a List called fruits to store strings.
The for loop iterates over each item in the list and prints it.

Conclusion

Dart is a beginner-friendly yet powerful language for modern app development. Whether you’re coding for web, mobile, or desktop, Dart provides the tools and simplicity to bring your ideas to life.
