Ignore internal errors in YamlEditor When we landed null-safety we accidentally disabled internal self-testing in YamlEditor. We fixed this in: https://github.com/dart-lang/tools/pull/2284 But this was reverted because this test broke. With this we should able to land: https://github.com/dart-lang/tools/pull/2299 TL;DR: `YamlEditor.update` may throw `AssertionError` if it has an internal error. Internal errors in `YamlEditor` should not happen, but we have bugs. There is open PRs to fix some of those bugs, but in practice it's not unlikely that there will always be bugs. We're modifying YAML source using `SourceSpan`s from the YAML parser. Changes in the parser, surprising corner cases, complex modifications or combinations of these can probably cause internal errors. These internal errors happens when: * The result YAML output is invalid YAML. * The resulting YAML doesn't match the same semantic modification on the original YAML structure, when compared with deep equals.

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.
