Warns when a dot shorthand invocation has an argument that is also a dot shorthand.

Nested dot shorthands significantly reduce readability (to a point where every instance is .new(.new(...))) and should be generally avoided.

Example​

❌ Bad:

void fn() {
  // LINT: Avoid nested dot shorthands as they significantly reduce readability. Try adding explicit types.
  final Another a = .new(.new(version: .new('val')));

  // LINT: Avoid nested dot shorthands as they significantly reduce readability. Try adding explicit types.
  final a = Another(.new(version: .new('val')));
}

class SomeClass {
  final String value;

  const SomeClass(this.value);
}

class Some {
  final SomeClass version;

  const Some({required this.version});
}

class Another {
  final Some some;

  Another(this.some);
}

✅ Good:

void fn() {
  final Another a = .new(Some(version: SomeClass('val')));

  final a = Another(.new(version: SomeClass('val')));
}
