 This sniff can cause an error if you're overriding or implementing a parent method which does not have typehints. In such cases add `@phpcsSuppress SlevomatCodingStandard.TypeHints.ParameterTypeHint.MissingNativeTypeHint` annotation to the method to have this sniff skip it.

 Sniff provides the following settings:

 * `nullPosition`: `first` requires `null` on first position in the type hint, `last` requires last position. None is set by default so `null` can be everywhere.
