Currently, dart:_js_types types are all typedefs in the web backends. This leads to inconsistent semantics, since you can statically pass Strings to JSString, for example. You cannot do this in dart2wasm. In order to ensure consistent semantics, we reify these types using a custom @staticInterop lowering. They all get erased to their respective Dart type. When we have inline classes, these types should be implemented using inline classes. Note that Interceptor will not work for this use case. The reified type of JS primitives are Dart types e.g. String, bool, and therefore can not be casted to Interceptor. In order to do this, the eraser is refactored and the JS backends use shared erasure code to either erase/emit types. Tests are added to make sure you need to go through a conversion or cast to pass Dart objects to JS types. CoreLibraryReviewExempt: Backend-specific internal library changes.

Dart
A client-optimized language for fast apps on any platform
Dart is:
-
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.
-
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
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).
