dart.library.js_util -> dart.library.js_interop for web detection

fishythefish · Commit Queue · commit 484c0b85b36c · 2025-09-27T13:58:09.000-07:00
dart2wasm will no longer support `dart:js_util`, so `dart.library.js_util` will be insufficient for detecting web backends. `dart:js_interop` is intended to replace it for the foreseeable future, so until we have an environment variable that more directly reflects whether the code is compiled with a web backend, we can use `dart.library.js_interop`. Other mentions of `dart.library.js_util` in tests are benign and aren't designed to detect all web backends specifically.
