Ask HN: Which is more important to Google's strategy, Dart or Go?

It seems obvious that Go has more users, and that with it, they build their servers and services. But that could also be done with Dart-vm, along with the browser interfaces and the mobile apps (Flutter) for their services.

Dart could also become a flagship language for developers targeting Google's platforms (if the whole Andromeda/Fuchsia OS leads that way and becomes semi-mainstream), the same way that Swift is Apple's flagship language.

To be clear, I'm not talking about the scope, design or features of each language (although that could be a considered point), but their importance to Google's strategy and dominance as seen from their point of view.
