Let's consider the most straightforward program on Dart.

As you can see, this program prints the phrase Hello, world!.

Code Syntax

Look at the void main()

• Every program needs the main() function, from which the code execution begins;
• void is a type of function. We will talk about types of functions in the future.

Curly Braces

Look at the curly braces {}

Dart code is written in the function's body, that is, in curly braces {}. The space in the curly brackets {} is the function's body, in which we will write all the commands that will work in this function.

Semicolon

Look at the semicolon ;

After each line of code, we put a semicolon. Otherwise, the development environment will report an error to us. Such line separation is necessary so that the dart interpreter knows where one instruction ends and where another begins.

Note

A Dart interpreter is a program that converts Dart code into machine code that a computer can execute. It works by reading Dart code, instruction-by-instruction, and converting them into a sequence of machine instructions. The computer can then execute these machine instructions.
