Learn Dart Comments

In Dart, comments are non-executable lines of text within your code that are ignored by the Dart compiler. They serve the purpose of providing explanations, notes, or context to human readers, including yourself and other developers who may work with your code. Dart supports both single-line and multi-line comments.

Types of Comments Single Line Comments : Single-line comments begin with // and extend to the end of the line. They are useful for adding brief explanations or annotations to specific lines of code.

// This is a single-line comment in Dart var age = 25; // This is another single-line comment

---

Multi-line Comments: Multi-line comments start with /* and end with */, allowing comments to span multiple lines. They are useful for adding longer explanations, commenting out blocks of code, or temporarily disabling sections of code.

/* This is a multi-line comment in Dart.
It can span multiple lines and is useful
for providing more detailed explanations.
*/
var name = 'Alice';

Documentation Comments (DartDoc): : Documentation comments are a special type of comment used to generate API documentation automatically. They start with /// for single-line comments or /** for multi-line comments.

Example:
/// This is a documentation comment for a function.
/// It provides a description of the function's purpose.
int add(int a, int b) {
return a + b;
}

Maintainence : Well-commented code is easier to maintain and modify because developers can quickly grasp its functionality and intent.
Collaboration: : Comments facilitate collaboration among team members by providing insights into the code's structure and design decisions.
Documentation Generation: : Documentation comments enable automatic generation of API documentation, which helps users understand how to use your code effectively.
