What is the current state of Google's Dart programming language? [closed]

Question

Dart has been out for ages (in internet years), but judging by Google Trends , it hasn't gotten much hype, and the fact that it only works in Chrome doesn't help either. Nonetheless, Chrome is gaining market share every day, which lends itself to a better view on Dart.

What is the big picture now? What state is the language in? Do people regard highly of it? Market share? Web App showcase? Some feature implementations that make you go "I have to use it"?
