Error: The method 'lookUpGetter2' isn't defined for the class 'InterfaceType'

I've been having this error:

I've tried to fix corrupted cache but it didn't help.

I think that means my dependency on analyzer is too loose, it needs a later version.

Does it work if you upgrade packages? Can you add a dependency on analyzer 0.39.3 to force it to be at least that version?

[minikin]

@davidmorgan I added analyzer: ^0.39.4 to dependencies and it fixed the error. Thank you for the advice!

Thanks for letting me know. I'll release 7.0.8 with correct lower bound for analyzer.
