Warns when a final field has the same initializer as another field in scope.

Fields with duplicate initializers are either the result of a typo or are redundant and can be simply removed.

Example​

❌ Bad:

class Some {
  final value = 'hello';
  // LINT: This field has the same initializer as 'value'.
  //  Try changing the initializer or reusing the existing field.
  final another = 'hello';
}

class Primary(String val) {
  final another = val;
  // LINT: This field has the same initializer as 'another'.
  //  Try changing the initializer or reusing the existing field.
  final third = val;

  final computed = val + val;
  // LINT: This field has the same initializer as 'computed'.
  //  Try changing the initializer or reusing the existing field.
  final anotherComputed = val + val;
}

✅ Good:

class Some {
  final value = 'hello';
  final another = 'world';
}

class Primary(String val) {
  final another = val;

  final computed = val + val;
}
