Warns when a enum constant has an unnecessary empty argument list.

Example

❌ Bad:

enum MyEnum {
  alpha.named(),
  beta.named(),
  gama(); // LINT: This argument list is unnecessary. Try removing it.

  final String value;

  const MyEnum.named() : value = '2';

  const MyEnum() : value = '3';
}

✅ Good:

enum MyEnum {
  alpha.named(),
  beta.named(),
  gama; // Correct, no argument list

  final String value;

  const MyEnum.named() : value = '2';

  const MyEnum() : value = '3';
}
