[VM/dartdev] Switch dartdev to use an AOT runtime. - split the Dart CLI tool out of the VM into it's own embedder which runs in AOT mode. The pure Dart VM executable is called 'dartvm' and has no Dart CLI functionality in it - the Dart CLI executable parses the CLI commands and invokes the rest of the AOT tools in the same process, for the 'run' and 'test' commands it execs a process which runs 'dartvm' to run - 'dart hello.dart' execs the 'dartvm' process and runs 'hello.dart' - the Dart CLI is not generated for ia32 as we are not shipping a Dart SDK for ia32 anymore (support to execute the 'dartvm' for ia32 architecture is retained) - the Dart CLI tool is not built in the internal Dart SDK builds TEST=ci Some performance improvement numbers 'dart format pkg/dartdev' goes from 1.17 secs to 0.22 secs 'dart doc pkg/dartdev' goes from 100.2 secs to 66.6 secs 'dart fix pkg/dartdev' goes from 19.3 secs to 14.5 secs Change-Id: I66984a26cb2ab014b34dc1873f1f3d2884e13518 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/364202 Commit-Queue: Ben Konyi <bkonyi@google.com> Reviewed-by: Ben Konyi <bkonyi@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.
See LICENSE and PATENT_GRANT.

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.
