Add a tools script to build a local Dart SDK and copy the output to a local Flutter SDK.

This script is helpful for testing local Dart SDK changes against a
Flutter project. This CL also adds instructions to the analysis_server
CONTRIBUTING guide.

The help output of the script looks like this:

> dart tools/copy_dart_to_flutter.dart -h
-a, --arch Specify your machine's architecture.
                                                     [ARM64 (default), X64]
    --[no-]build-sdk                                 Whether to build the Dart SDK as part of running this script. Negate with --no-build-sdk if you have already built the Dart SDK locally and want to skip this step.
                                                     (defaults to on)
-d, --local-dart=</Users/me/path/to/dart-sdk/sdk> Path to your local
Dart SDK directory. If unspecified, this value will default to the value
of the LOCAL_DART_SDK environment variable.
-f, --local-flutter=</Users/me/path/to/flutter> Path to your local Flutter
SDK directory. If unspecified, this value will default to the value of
the LOCAL_FLUTTER_SDK environment variable. -v, --verbose Run the script
with verbose output, which will forward the stdout and stderr of all
sub-processes. -h, --help Show the program usage.

Additional commands
    --reset                                          Reset your local Flutter SDK cache to undo the effects of running this script.

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).
