Describe the bug

"Find all references" seems to discriminate between this. parameters and the fields they map to. I don't think there should be a distinction.

To Reproduce

Create these two classes:

class X {
  int x;  // (1)
  X({required this.x});  // (2)
}
class Y {
  void foo() {
    X(x: 1);  // (3)
  }
}

Actual behavior

The numbers (1), (2), and (3) infer positioning the cursor at x on the correspondingly numbered line, and then right-clicking and selecting "Find all references":

• "Find all references" at (1) finds only (1) and (2).
• "Find all references" at (2) finds only (1) and (3).
• "Find all references" at (3) finds only (2) and (3).

Expected behavior

"Find all references" at any of (1), (2), or (3) should find all three.
