Comments in Dart Programming
Comments are a set of commands that are ignored by the compiler. They are used in a scenario where you want to attach a note to your code or a section of code so that when you visit it later, you can recall it easily.
The comment statements are usually ignored during the execution of the program.
There are multiple types of comments in Dart, mainly these are −
Single line comments
Multi-line comments
Documentation comments
We will explore all the above document types in this article.
Single Line comments
Single line comments make use of // (double forward slash). They extend up to a new line character.
Syntax
// this is a comment
Example
void main(){
// var x = 10;
print("Hello World");
}Output
Hello World
Multi-line comment
A multi-line comment makes use of /* */. Everything put between the opening /* and the closing */ will be ignored by the compiler.
