I was thinking a bit more about this fix, and I have three things to talk about:

1. It should probably get renamed to Create enum constant so it is more aligned with all other Create (extension) <member> fixes.
2. Missing case:

enum E { a(1); const E(int i); } void f(E e) { f(E.b); // Only displays `Change to 'a'` }

(Congrats @kallentu for fixing this for dot sorthands!)

3. When we have a constructor that takes parameters, we should create the constant and move the selection there with a null as a parameter, so the user knows they must fix it, like:

enum E { a(1); const E(int i); } void f(E e) { f(.b); // would add above `b(null)` }

Like we would for other fixes, like getter and such, where we fill:

 E get b => null;

WDYT @bwilkerson?
