unnecessary_underscores

Unnecessary underscores can be removed.

AVOID using multiple underscores when a single wildcard will do.

BAD:

void function(int __) { }

GOOD:

void function(int _) { }

To enable the unnecessary_underscores rule, add unnecessary_underscores under linter > rules in your analysis_options.yaml file:

linter:
  rules:
    - unnecessary_underscores

If you're instead using the YAML map syntax to configure linter rules, add unnecessary_underscores: true under linter > rules:

linter:
  rules:
    unnecessary_underscores: true
