weird equality issue

main.dart

List<int> integersUntil(int limit) => [for (var i = 0; i < limit; i++) i];

class Foo {
  final List<int> bar;
  final List<int> baz;
  const Foo(this.bar, this.baz);
  @override
  bool operator ==(Object other) => other is Foo && other.hashCode == hashCode;

  @override
  int get hashCode => Object.hash(bar, baz);
}

void main() {
  final foo1 = Foo(
    integersUntil(10),
    integersUntil(100),
  );
  final foo2 = Foo(
    integersUntil(10),
    integersUntil(100),
  );

  print(foo1 == foo2);
}
