@srujzs - quick interop question. If I have a JS object, how to I access named fields (like 'PWD' or 'PATH').

Context: https://nodejs.org/api/process.html#processenv

[devoncarew]

ah, JSObjectUnsafeUtilExtension.getProperty :)

[devoncarew]

Should the docs for https://api.dart.dev/stable/latest/dart-js_interop_unsafe/JSObjectUnsafeUtilExtension.html be updated? It says but takes and returns a Dart value but the sig indicates it takes a dart value and returns a JSAny.

[srujzs]

Yup, or just []. You could also add an extension type for _env and add external fields with the expected names.

Thanks for the catch! https://dart-review.googlesource.com/c/sdk/+/409480

@srujzs - also, I don't see a .toJS on Dart Maps, but do see a toJSBox. Here, I'm trying to convert to a regular JSObject.

[srujzs]

I'd just use .jsify() like you were before - it's just an extension method now. This should translate the map into a JS object using the string keys as property names just like before. toJSBox creates an explicit box around the object so that you can pass it back to the Dart runtime later so it's not the right fit.
