Dart Comments
The collection of statements known as comments are those that the Dart compiler ignores while the program is running. It is applied to improve the source code’s readable quality. Generally speaking, comments provide a concise overview of the code’s contents. Variables, functions, classes, and every statement that appears in the code can all be explained in detail. The comment should be used by programmers to improve their work. The Dart allows for three different kinds of comments.
Types of Comments
Dart offers three different types of remarks.
- Single-line Comments
- Multi-line Comments
- Documentation Comments
Single-line Comment
Applying comments to a single line is possible with the // (double-slash) character. Up to a line break, the single-line comments can be used.
Example
void main(){
// This will print the given statement on screen
print("Welcome to JavaTpoint");
}
Output
Welcome to JavaTpoint
The Dart compiler retunes the output and completely ignores the // (double-slash) statement.
Multi-line Comment
/*…..*/ can be used to apply comments across many lines when necessary. Anything typed inside the /*…*/ is ignored by the compiler, however multi-line comments cannot be nested inside of it. Now let’s look at an example.
Example
void main(){
/* This is the example of multi-line comment
This will print the given statement on screen */
print("Welcome to JavaTpoint");
}
Output
Welcome to JavaTpoint
Dart Documentation Comment
Document comments are used to create project/software package documentation or references. It can begin with /// or /* and be a single line or multi-line comment. The multiline comment can also be used with /// on successive lines. The Dart compiler ignores all of these lines save for the ones that are written inside curly brackets. Classes, functions, parameters, and variables can all be defined. Think about the example that follows.
Syntax
///This
///is
///a example of
/// multiline comment
Example
void main(){
///This is
///the example of
///multi-line comment
///This will print the given statement on screen.
print("Welcome to JavaTpoint");
}
Output
Welcome to JavaTpoint
