It looks like IntelliJ had a problem upgrading the Dart plugin. Try removing it and re-installing. If you are still having problems then you might be able to get help from JetBrains. Just to be clear, I checked and the missing class is still in the Dart plugin. I had no problems upgrading, although I did upgrade the plugin before upgrading IntelliJ. Let us know if that works.

Reinstallation works for me

[Panaith]

Yes, re-installing the plugin does the trick. Thank you very much

[stevemessick]

Great, thanks for the update.
