Update description

[MahanRahmati]

How can I update description of my repository?
I want to change it to:

• arna - A set of widgets designed to be simple and easy to use for building applications with Flutter. (Live Preview)

This description is from the description of pub, if you update the description in pubspec.yaml and republish it, I will update it
