source maps aren't requests when running via pub serve

[sethladd]

I don't see a source map file being sent, when serving my app over pub serve.

See screenshot.

I was hoping to debug via source maps when using pub serve ?

FWIW here's what it looks like when I just "run as javascript"

(notice the talk_to_me.dart.js.map request)

"pub serve" just starts an HTTP server. The browser is responsible for whether or not it requests a given file.

Can you manually request the source map file?

Looks like pub serve isn't adding the trailing comments to the end of the app.dart.js file. The comments tell the dev tools about source maps.

Something like this:

//# sourceMappingURL=/path/to/file.js.map

To verify, run dart2js from the command line and check out its output.
