unnecessary_const_in_enum_constructor

Don't use an explicit const in a generative enum constructor.

Don't use an explicit const in a generative enum constructor. Generative enum constructors are implicitly const.

BAD:

enum const E(final int i) {
  a(1), b(2);
}

enum E {
  a(1), b(2);
​
  const E(this.i);
​
  final int i;
}

GOOD:

enum E(final int i) {
  a(1), b(2);
}

enum E {
  a(1), b(2);
​
  E(this.i);
​
  final int i;
}

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

linter:
  rules:
    - unnecessary_const_in_enum_constructor

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

linter:
  rules:
    unnecessary_const_in_enum_constructor: true
