This has got to be the worst learn x in y minutes that I've ever read. Whitespaces, anyone? Every example is compacted and very hard to read. Comments should document each line instead of a huge wall of text before the function.

Naming everything ExampleX is very difficult to see what is being talked about in this particular function.

I'm lucky to know enough about Dart already, because this is a very bad representation of it, IMO.

Perhaps you could contribute to the file via a PR instead of ranting at a post on a news aggregator? If people like you did then the open source community would be a better place.

"Make a pull request" is not a proper way to respond to valid criticism of open source projects. Is it not obvious how fallacious that argument is?
