Code

$user = User::first();
$user->gender = 'm';
$user->isDirty('gender');

Output

In UserFactory.php line 12:
                                                                               
  Unparenthesized `a ? b : c ? d : e` is deprecated. Use either `(a ? b : c)   
  ? d : e` or `a ? b : (c ? d : e)`
