  I just follow this reference <a href="https://github.com/idrcorner/Flutter-Login-MySQL/blob/master/lib/main.dart" rel="nofollow noreferrer">link</a>.  It would be great if anybody could figure out, thank you so much in advance!.</p>

  <pre><code>Future&lt;List&gt; _login() async {
     final response = await http.post(&quot;http://10.0.2.2/my_store/login.php&quot;, body: {
        &quot;username&quot;: user.text,
        &quot;password&quot;: pass.text,
