Pro+

Suggests removing an unnecessary empty constructor for enum and class declarations.

Example

❌ Bad:

class SomeClass {
  final values = <int>{};

  SomeClass(); // LINT
}

enum MyEnum {
  alpha,
  beta,
  gama;

  const MyEnum(); // LINT
}

✅ Good:

class SomeClass {
  final values = <int>{};
}

enum MyEnum {
  alpha,
  beta,
  gama;
}
