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.
