[vm/aot] Keep toString methods on exception classes in toString transformer Flutter in google3 uses --delete-tostring-package-uri compiler option to remove toString methods in package:flutter and dart:ui to reduce size in release mode. This has unfortunate effect of removing toString methods from exception classes which may provide valuable information for investigating problems seen in the wild. This change adds a new @pragma('flutter:keep-to-string-in-subtypes') on classes to keep toString methods on all subtypes of the annotated classes. This pragma is now used on Exception and Error classes in dart:core.

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.
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.
