Comments in DartComments are necessary when the length of code is too long usually thousands of lines per file. When you share your code to others, a well commented code is easy to understand for any other person who will read it. This is better than cracking our heads on what a for loop iterates on!
This helps even for our reference of same code after a significant amount of time. Because it's usual that we don't remember all the code we write, right?
To make comments in dart we use following syntax:
1. //This is a comment
2. int a = 100; // This is a comment after a code statement
3. /* This is a
5. comment */
