Use dart: 2.0.0-dev.40.0, could be possible, it's fixed. But no promises!

[rwrozelle]

Still broken after update to dart: 2.0.0-dev.40.0. No luck.

[sigmundch]

I landed a fix for this issue last night, but unfortunately it didn't make it on version 2.0.0-dev.40.0, but should make it in version 2.0.0-dev.41.0

The issue comes up only if you are using --no-frequency-based-minification, so if you can work for now without that flag, that should hopefully unblock you until the next release (which is expected in a couple days I believe).

I'll mark this as a duplicate of #32600, but let me know if you think there is a different problem at play here.

Cheers!
