The public backing by Google absolutely propelled Go into the spotlight, but Dart, also released by Google, hasn’t achieved anywhere near the same success. Considering how long ago Go was released, if the language didn't have its own merit, it would have fizzled out by now and failed to sustain its momentum or foster such a strong community.

Dart was never marketed (to my knowledge) as a general-purpose programming language. Go was marketed as the best thing since sliced bread, and especially as a "systems language", which it definitely isn't. It was also gaining popularity on HN at the same time Rust was gaining its initial wave of popularity (~2016-2017, around when I started reading HN), so the two were compared and written about a lot in a way that Dart never had the chance to since it never had a narrative foil.
