Nate Biggs 600f8a9601 [dart2wasm] Use default value sentinel when member body unreachable
This issue was partially fixed by:
https://dart-review.googlesource.com/c/sdk/+/428541

However, this only looked at the case of a member in an abstract class
that itself was made abstract if it was unused. TFA does not make the
member abstract if the enclosing class is not abstract:
pkg/vm/lib/transformations/type_flow/transformer.dart#L2289

Instead we can use the unreachable metadata to identify these
unreachable body members (that have default values cleared):
pkg/vm/lib/transformations/type_flow/transformer.dart#L736

Attached test fails prior to this fix.

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).
