Bogus unnecessary_this with pattern matching and shadowing

[nex3]

For the code below:

class Foo {
  Object? value;

  bool equals(Object other) => switch (other) {
    Foo(: var value) => this.value == value,
    _ => false
  };
}

the 3.0.0 analyzer will print

info - test.dart:5:25 - Unnecessary 'this.' qualifier. Try removing 'this.'. - unnecessary_this

This is incorrect. The this. is necessary to disambiguate the containing class's value field from the value variable bound by the switch expression.

Good catch. Taking a look now. Thanks!

It looks like the issue is percolating up from analyzer.

Tracking in #52486

@pq Is there an ETA on this ending up in a released Dart version? It looks like Dart 3.0.7 is still surfacing the bogus lint.

My understanding is that a Dart 3.1 release is slated for the next few weeks. (@itsjustkevin could confirm?)
