EASY WAY TO PRNT HELLO WORLD IN DART

Introduction

Dart is a modern programming language developed by Google, designed for building scalable web, mobile, and server applications. Writing a “Hello World” program is the most basic way to start learning any language. In this guide, we’ll write a simple “Hello World” program in Dart, understand the structure of the code, and examine the output.

Dart Program: “Hello World”

Here’s the code to print “Hello World” in Dart:

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

EXPLANATION OF THE CODE

1. void main():
   This is the entry point of every Dart application. The main() function is where the execution starts. It doesn’t return any value, so it is declared as void.
2. { and }:
   These curly braces define the start and end of the main() function. All the instructions that need to be executed are placed inside these braces.
3. print('Hello, World!');:
   The print() function is used to output text to the console. Here, it prints the string 'Hello, World!' to the console. In Dart, strings are enclosed in single quotes (') or double quotes ("), but in this case, we are using single quotes. The semicolon (;) at the end of the line indicates the end of a statement.

Output

When you run this program, the following will be printed to the console:

Hello, World!

Conclusion

This simple “Hello World” program in Dart provides an excellent starting point for beginners. It demonstrates how to define a function, use the print() function, and write a basic Dart program. As you explore more advanced topics, understanding these fundamental concepts will serve as a foundation for learning the Dart programming language.
