Augment. Replace fragment isSynthetic with origin flags. Remove FragmentImpl.isSynthetic and record synthesized fragment origins using more specific isOrigin... flags instead. This adds dedicated origin markers for formal parameters and type parameters synthesized to keep augmentation fragments aligned, and for formal parameters synthesized for mixin application constructors. It also stops marking other generated fragments as synthetic when their origin is already represented by a more specific flag such as isOriginVariable, isOriginGetterSetter, isOriginLoadLibrary, or isOriginNotExistingFile. Update summary serialization to preserve the new fragment flags and bump the data version. This makes generated fragment provenance more precise and avoids collapsing different synthesized cases into one generic synthetic marker.

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.
See LICENSE and PATENT_GRANT.
