Dart program

Here’s an example of a simple dart program that prints “welcome vcanhelpsu!” to the console.

void main() {

  print(‘welcome vcanhelpsu!’);

}

Let’s understand this program down.

The void keyword indicates that this program doesn’t return a value.

Main() is a special function that serves as the entry point of the program. All dart programs must have a main() function.

The curly braces {} indicate the beginning and end of the function body.

The print() function is used to display a message on the console.

When you run this program, it will output “welcome vcanhelpsu!” to the console.

Remember, that dart is a whitespace-sensitive language, which means that indentation matters. In the above example, the print() statement is indented with two spaces. While this isn’t strictly necessary, it’s a common convention in dart code to use two spaces for indentation.
