Opinions on Dart’s Isolates?

I’ve been looking into Flutter a bit as a platform for phone apps, and 
that got me looking into the Dart language. Their approach to 
concurrency feels awful familiar, with “isolates” looking a lot like 
Erlang processes. It’s actually pretty cool, nice and clean, albeit 
wrapped in some OO noise. I imagine, though don’t know, that they were 
influenced by Erlang/Elixir, although I suppose something like parallel 
evolution of the Actor model could be responsible as well (sharks and 
whales look a lot alike).

Anyway, I wondered what other Erlangers thought about it. You can find 
an overview here:
