Class 'Parser' has no instance setter

[Hecatoncheir]

HI. I try update polymer from "^0.16.4" version, to '^1.0.0-rc.5', and after run pub serve I get an error:

Build error:
Transform WebComponents on no matter|web/index.html threw error: Class 'Parser' has no instance setter 'parseConditionalDirectives='.

NoSuchMethodError: method not found: 'parseConditionalDirectives='

I do all steps from Migration Guide. What was could happen?

It looks like the error is actually coming from the dart_style package, where it is setting up the analyzers Parser with parseConditionalDirectives = true. My guess is this is a result of the dependency override on the analyzer, which is forcing a lower version than dart_style wants (which doesn't define that property).
