sort_unnamed_constructors_first

Invalid location for the unnamed constructor.

The analyzer produces this diagnostic when an unnamed constructor appears after a named constructor.

The following code produces this diagnostic because the unnamed constructor is after the named constructor:

class C {
  C.named();

  C();
}

Move the unnamed constructor before any other constructors:

class C {
  C();

  C.named();
}
