title: How to return value when navigator to another page in Flutter?
body: <p>I have a code like this:</p>
  <pre><code>Navigator.push(context, MaterialPageRoute&lt;String&gt;(builder: (context) =&gt; bolatAktar_bolatAktar_filtrelemeSonucu()));
  </code></pre>
  <p>When going to the <code>bolatAktar_bolatTransfer_filterlemeResult()</code> page, I want to import data that I can use on that page. I will send a total of 2 data. One is double and the other is String type data. How can I do that?</p>
  <p>Thanks in advance for your help.</p>
