I'm not really sure where it slots in in a world with a lot of programming language choices. Why would I use it over something like Rust, Go, or even JavaScript

Come for the Flutter, stay for the extras.

  Exactly. I use it for a full stack mobile app development. Backend and frontend can share code. Server can be compiled to a single machine code binary.

    That’s really interesting and compelling. What’s the rest of your backend stack look like? Do you get good performance from the database drivers written in dart?

I mainly just trust Bob Nystrom (https://news.ycombinator.com/user?id=munificent https://news.ycombinator.com/user?id=munificent) to keep this thing on the rails. He's an excellent language designer.

  > Dart has a first-class mobile story, unlike Rust + Go Not really, the Android team doesn't even list it as supported language, a team that belongs to the same employeer. The same team not only lists Rust, it has official documentation on the Android site for OEMs, on how to use Rust.

>Why would I use it over something like Rust, Go, or even JavaScript? Honestly, mainly for flutter. But if you do chose flutter for your project, you will suddenly wish everyone was using dart for everything else instead of Java on android, or c#/Swift on ios ect. if that makes sense. If sound type checking is truly feasible on the web then I'd say dart should be there too. But I can't say if that's really the case. At least ECMA seems to think it isn't, at least for js.

  > Java on android You mean Kotlin? Nah. Dart is ok. It doesn't perform as well as those peer languages. It's nice its FFI story is good, but the ecosystem is very weak even compared to Javascript. As for the tooling. It's decent. I wouldn't call it amazing, unless you come from systems that were anemic to begin with, then it seems pretty amazing. As for flutter. I recently installed it again. A test app with a single CupertinoTextField consumes 45% of an Intel core on a linux desktop (Wayland and X11 were similar). Like, goodbye. Maybe if WORA means iOS and Android, fine, I get that is the common use case. But that is wishful thinking to false advertising as far as I care. https://github.com/flutter/flutter/issues/125388 https://github.com/flutter/flutter/issues/125388 https://github.com/flutter/flutter/issues/101591 https://github.com/flutter/flutter/issues/101591 (going on 2 years!) I also believe Google will shit can both this and Fuchsia, because Google is CADT baked into its organizational structure.

      Eternally, as long as that text field has focus with the animation of a blinking cursor. I'm not telling my customers to make sure they're not "holding it wrong" by deigning to leave the app in the foreground and killing their battery.
