From the project README

An excerpt from the repository, fetched Nov 13, 2026.

Read the project’s introduction
Dart An approachable, portable, and productive language for high-quality apps on any platform Dart is: Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns. Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web. Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools. Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals: Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code. Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js). License & patents Dart is free and open source. See LICENSE and PATENT_GRANT. Using Dart Visit dart.dev to learn more about the language, tools, and to find codelabs. Browse pub.dev for more packages and libraries contributed by the community and the Dart team. Our API reference documentation is published at api.dart.dev, based on the stable release. (We also publish docs from our beta and dev channels, as well as from the primary development branch). Contributing to Dart See the contribution guide for details. Building Dart If you want to build Dart yourself, here is a guide to getting the source, preparing your machine to build the SDK, and building. There are more documents in our repo at docs. Roadmap Future plans for Dart are included in the combined Dart and Flutter roadmap on the Flutter wiki.

Dart isn't perfect, and I think at the least would really benefit from Union types. There are some open issues related to these things though: https://github.com/dart-lang/sdk/issues/4938 (Unions) https://github.com/dart-lang/sdk/issues/421 (Tuples) Please feel free to contribute here! That said, it's certainly possible to work around these things. Dart has a tuple library (https://github.com/dart-lang/tuple) which covers a lot, and much of what you'd use Unions for can still be covered by accepting `Object` or `dynamic` parameter types and doing some typechecking.

The great development experience is largely tied into Dart and it's toolchain, not to mention all of the underlying Dart code in the project. However, you can get the same kind of control flow out of Dart albeit with a little less static checking (https://github.com/dart-lang/sdk/issues/33079) so from a pragmatic standpoint this really shouldn't be something that's holding you back. The cost of not having ADTs is much lower than the cost of maintaining two separate iOS and Android apps (or even dealing with the downsides of other cross platform approaches IMO).

Dart's history of breaking on browser updates because of weird technical decisions really soured me on the idea of ever using it. It's apparently a really good language for native targets, but for the web... https://github.com/dart-lang/sdk/issues/13285 https://bugzilla.mozilla.org/show_bug.cgi?id=1027011 I can't really blame the language designers, but it's a good example of how if your goal is to cross-compile you have to be very careful about how your language is going to interact with the realities of the platforms it runs on. The idea of my deployed websites or apps breaking every couple browser releases really bums me out. (I've had to deal with it with other cross-compilers too.)
