Comments
Developers often need a tool to make their code easier to understand. It’s often helpful for himself and the people he works with on code. A comment is a text that the Dart interpreter ignores, allowing us to explain parts of the code. There are several main uses for comments.
An explanation of what the code does:
main
void main() { print('Correct'); // Output word correct to console }
We often comment out code blocks to avoid errors at runtime:
main
void main() { print('Hello, World!'); //; print Hello, World!"'() print("Hello, World!"); }
Code Syntax
Dart supports single-line comments // and multi-line comments /* */.
Single-line comment:
main
void main() { print('info'); // Output 'info' to console }
Multi-line comment:
main
void main() { /* multi-line comment */ print("Very useful topic"); }
