@DanTup I’ve seen this happen a couple of times. I’m building that SDK and reloading it when DartCode detects the SDK has been updated, in cases that’s relevant. (I’m adding new APIs to dart:* libraries.)

Is this an error in how DartCode invokes the summaries? Or is it an error in the SDK?

[innomatica]

In my case, it usually happens when I select a block of code and hit the Ctrl-C key. Once it happens it shows two identical errors.

I get about 20-30 of these messages a day. Restart seems to help for about ~5mins but then I see these again. I just ignore them as they don’t seem to affect anything noticeable and my code is still being saved and working.
