Danny Tuppeny 4d07f9ace4 [vm_service] Use empty lists instead of null for non-optional fields when parsing JSON
Change 64060a8ddf accidentally lost `?? []` for non-optional fields when parsing JSON. This change restores that (in `generate_dart_common.dart`), along with some minor tweaks to get the codegen to work on Windows.

For reasons I don't understand, the generated files were formatted differently to how the formatter formats them on my machine today, which unfortunately makes the diff larger than the intended change.

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).
