@override void run(CustomLintResolver resolver, ErrorReporter reporter, CustomLintContext context)

Emits lints for a given file.

run will only be invoked with files respecting filesToAnalyze

Implementation

        }
        continue;
      }

      // PropertyAccess (e.g. `Foo.bar` where `bar` is a static method) is
      // already an Identifier after resolution in most analyzer versions;
      // anything else is conservatively rejected.
      reporter.atNode(inner, code);
