Happened after upgrading to 1.24.0 (via brew). I did a brew switch 1.23.0 and the console for that version was then also not working. I did a full uninstall and reinstall, and still no console.

I was launching it via DART_FLAGS='--checked --load_deferred_eagerly' open /Applications/Chromium.app, but same issue when opening via open /Applications/Chromium.app.
@terrylucas - can you please take a look?
Same issue on Linux Ubuntu MATE 17.04.
I believe I've narrowed this done to the fact that debuggerModel could come up null in some edge cases causing a fatal error trying to call addEventListener. Only happened in some obscure cases most pages with just JS seem to work.
See CL
Thank you! Will this be incorporated into the dartium that ships with dart 1.24.0, or do we need to wait for the next version?
It should make it into the next 1.24 stable -- I'll keep you posted. Working on one more fix for WebStorm debugging that needs to make it into 1.24 stable.
Also having this issue since upgrading to 1.24.0 via brew. 1.24.1 doesn't fix.

Released in 1.24.2
