This package is deprecated.
Before it was deprecated, it was the way to get analysis options matching those used internally at Google. This was useful because it was a good starting point for which lints to enable.
Instead, please see package:lints which is the lint recommendation from the Dart team, or package:flutter_lints which extends that for Flutter. These are better than the Google lint set because they take into account the needs of all Dart users, not just Google engineers.
To migrate away from
package:pedantic please see the instructions here.
