title: How to check a group of text edit controllers to see if any of them are null?
body: <p>I'd like to have a function that checks to see if any of the text edit controller fields are null.</p>
  <p>I wrote this method below, but I wanted to see if there was a more elegant solution.</p>
  <pre><code>bool _nullfieldExists(){
    //return a true if any of the textEditController fields are null
    if (_textEditControllerNumberPlayers.text == null ){
      return true;
    }
    else if (_textEditControllerSmallBlind.text == null ){
      return true;
    }
    else if (_textEditControllerBigBlind.text == null ){
      return true;
    }
    else if (_textEditControllerAnte.text == null ){
      return true;
    }
    else if (_textEditControllerMyStack.text == null ){
      return true;
    }
    else {
      return false;
    }   
  }
  </code></pre>
