I love the idea of Flutter, but tying it to Dart just seems like a way to guarantee it'll have a long slog to getting larger-scale usage. It feels like Google had a language that had no users and had to use it for _something_.
Dart as a platform provided the unique ability to target both JIT at development-time to enable sub-second hot reload and AOT for release apps, providing native performance when it comes to scrolling, animation, etc.
I'm kind of curious why they haven't tried to bring Go to more domains. Back in 2015 I thought by now they'd have released a framework for building Android apps in Go.
Dart came out the same year as Kotlin.. it's not like this decision was made this year (they're both 10 years old).
Re: Sibling comment it really is an order of magnitude better than many other languages. It's worth giving a try. Null safety alone is worth it (although other languages like C# now support this too).
