Describe the bug

Create this class:

class _MyClass {
  int? param;
  _MyClass({
    this.param,
  });
}

Now hit save. You get:

class _MyClass {
  int? param;
  _MyClass();
}

this.param is removed automatically, because it is (as yet) unused.

This is not good default behavior. (Or maybe I accidentally enabled it in my settings, but it's not good behavior in general.)
