Dart Comments

Dart Comment Syntax

Dart comments use // and /* */ with DartDoc for documentation.

Introduction to Dart Comments

Comments in Dart are a vital part of writing clear and maintainable code. They help you explain and document your code to make it easier for others (or yourself) to understand later. Dart supports single-line comments, multi-line comments, and documentation comments (DartDoc).

Single-Line Comments

Single-line comments in Dart are initiated using two forward slashes //. Everything following // on that line is considered a comment and is ignored by the Dart compiler.

Multi-Line Comments

For longer comments that span multiple lines, you can use multi-line comments. These are enclosed between /* and */.

DartDoc Comments

DartDoc comments are used for generating documentation for your code. These are written using triple slashes /// or enclosed in /** */. They typically appear before declarations such as classes, methods, or functions.

Best Practices for Using Comments

While comments are useful, they should be used judiciously. Here are a few best practices to follow:

  • Be concise: Keep comments short and to the point.
  • Keep comments relevant: Ensure comments accurately reflect the code they describe.
  • Avoid obvious comments: Do not comment on self-explanatory code.
  • Maintain updated comments: Update comments as the code changes to avoid misinformation.
