bookDart Comments

メニューを表示するにはスワイプしてください

Developers use comments to make code easier to understand. The Dart interpreter ignores them, allowing you to explain what the code does or clarify its purpose.

main.dart

main.dart

copy

              
123

            
void main() {
  print('Correct'); // Outputs word Correct to the console
}

You can comment out code blocks to prevent them from running. This is helpful for avoiding runtime errors or testing specific parts of your code.

12345

            
void main() {
  // print("This is a test!");
  print('Hello, World!');
  // print Hello, World!"'()
}

Dart supports single-line comments // and multi-line comments /* */.
