Reland "[vm/ffi] Introduce `Struct.create` and `Union.create`" Analyzer fix https://github.com/dart-lang/sdk/issues/54754 has landed. A new version of package:analyzer and package:dartdoc have been released. `pub global activate dartdoc` should now work. Patchset 1 is identical to the original CL. The only difference is an extra test testing with negative offsets. === Original CL description === Structs and unions can now be created from an existing typed data with the new `create` methods. The typed data argument to these `create` methods is optional. If the typed data argument is omitted, a new typed data of the right size will be allocated. Compound field reads and writes are unchecked. (These are TypedDataBase loads and stores, rather than TypedData loads and stores. And Pointers have no byte length.) Therefore the `create` method taking existing TypedData objects check whether the length in bytes it at least the size of the compound.

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.
