Is there an existing issue for this?

Use case

I was trying to look for an implementation of the cupertino_icons but there wasn't any example present on pub.dev. So, I think we should provide an example app.

It would also increase the pub points on cupertino_icons. Currently, it's 120/140.

I would be happy to contribute to this.

Proposal

There should be an example app present on all of the packages as it makes implementation really easy for any developer.
