Create Comments In Dart

Dart is a powerful language used to create powerful, efficient and scalable web, desktop, and mobile applications. A substantial element while learning Dart is understanding how to create comments that help in understanding the flow of the code and enhance its readability.

Code snippet for creating comments in Dart

In Dart, you can create single or multiline comments. Here are some examples:

// This is a single line comment

/* 
This is a multiline comment.
You can write in multiple lines.
*/

/// This is a documentation comment.
// Used to document libraries, classes, and their members.

Code Explanation for creating comments in Dart

1. Single-Line Comments

Single line comments in Dart start with //. Everything to the right of // on the same line is considered as a comment.

Example:

void main(){
  // This line of code will print a string in the console
  print('Hello World');
}

In the above-mentioned example, the statement following // is a comment.

2. Multi-Line Comments

If you want to create a comment that spans multiple lines, you can do so in Dart with /* / . Everything between / and */ is considered as a comment.

Example:

void main(){
  /* This is the main function,
  execution starts from this function
  */
  print('Hello World');
}

In the example above, the lines between /* and */ are considered as comments.

3. Documentation Comments

To document libraries, classes, and their members, you can use /// for single-line doc comments and /** … */ for multi-line doc comments.

Example:

/// This function prints a string in the console
void main(){
  print('Hello World');
}

The line starting with /// is a documentation comment, describing the functionality of the main function.

Learning to create and use comments effectively in Dart can take your programming skills to a higher level by allowing you to write clean, understandable code, which is important when working collectively on projects or for future reference. Whether you are a beginner or an experienced programmer, always remember the importance of commenting your code in any programming language.
