[dartdev] Organize `dart --help` commands into categories This CL organizes the commands in the Dart CLI to categories. It mirrors the categories used in `flutter --help`: `SDK`, `Project`, and `Tools`. The available command section will now look as follows in verbose mode: ``` Available commands: Project build Build a Dart application including native assets. compile Compile Dart to various formats. create Create a new Dart project. pub Work with packages. run Run a Dart program. test Run tests for a project. Source code analyze Analyze Dart code in a directory. doc Generate API documentation for Dart projects. fix Apply automated fixes to Dart source code. format Idiomatically format Dart source code. Tools compilation-server Control resident frontend compilers. development-service Start Dart's development service. devtools Open DevTools (optionally connecting to an existing application). info Show diagnostic information about the installed tooling. language-server Start Dart's analysis server. tooling-daemon Start Dart's tooling daemon. ``` Bug: https://github.com/dart-lang/sdk/issues/60980 Change-Id: Ic9da297fcdd0f8e85d619632ba8ec30fd2c32666 Cq-Include-Trybots: luci.dart.try:pkg-linux-debug-try,pkg-linux-release-arm64-try,pkg-linux-release-try,pkg-mac-release-arm64-try,pkg-mac-release-try,pkg-win-release-arm64-try,pkg-win-release-try Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/436382 Reviewed-by: Michael Thomsen <mit@google.com> Commit-Queue: Daco Harkes <dacoharkes@google.com>
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).
Dart is free and open source.

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).
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.
The easiest way to contribute to Dart is to file issues.
You can also contribute patches, as described in Contributing.
Future plans for Dart are included in the combined Dart and Flutter roadmap on the Flutter wiki.
