May be it seems simple but I'm interested about knowing the exact differences between Doc Comments and Comments in Dart.
/// this is a Doc Comment
// this is a Comment
Comments (//)
Comments usually used to comment out some part of your code or adding some comments in your code, which you want to communicate with your team-mates.
Doc Comments (///)
Doc comment is for documentation purpose. The dartdoc parses doc comments and creates documentation pages.
