[question] What library to use for conditional imports on web now?

[parlough]

dart.library.js_interop and dart.library.js_interop_unsafe don't seem correct as they don't suggest that the code is running on the web.

Sure I can still rely on dart.library.html for now, but what if I want my code to continue working in a world where that no longer exists? Can some arbitrary target be introduced for web compilation?

dart.library.js_interop is the right thing.

You should do feature detection to detect web vs node for instance.

Hmm, then I think it'd be nice to have some other (stable) constant to go along with --server-mode (or some successor like --no-web) to enable tree shaking otherwise some uses may end up shipping a lot of dead code. An implementation of something for the web vs node (or similar) could easily be completely different.

Maybe that's needed anyway as I can see developers wanting a consistent way to determine if their code is running in a browser or not (perhaps relevant to the package:platform work and Wasm too) :)

Closing this as the question was answered. Will pursue the target-platform based tree shaking in discussions surrounding the new form of the platform package.

Thanks Kevin! :D
