Reland "[vm] Migrate FFI callbacks to the new metadata system." This reverts https://dart-review.googlesource.com/c/sdk/+/306674 Patchset 1 is a pure rollback of the rollback. Patchset 2 is https://dart-review.googlesource.com/c/sdk/+/306316 Patchset 4+ is the forward fix for the Fuchsia issues. The Fuchsia bug that we're fixing (or working around), is that VirtualMemory::DuplicateRX doesn't work on Fuchsia. A proper fix will require special casing it, like on MacOS. In the mean time we can avoid using this function by only allowing one page of trampolines on Fuchsia. Unfortunately, when I removed the BSS stuff from the original CL, it was necessary to duplicate even the first page, so I've had to add that stuff back just for Fuchsia.

Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
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.
