title: Flutter: Send JSON body with dio package get request
body: <p><img src="https://i.stack.imgur.com/wIaeL.png" alt="this API is working normal in postman" />
  however in flutter app its returning this</p>
  <p>{&quot;success&quot;: true,
  &quot;rslt&quot;: []}</p>
  <p>where &quot;rslt&quot; is empty.</p>
  <p>here's my code</p>
  <pre><code>dynamic getData(dynamic token) {
  dio.options.headers['Authorization'] = '$token';
  return await dio.get&lt;dynamic&gt;('https://address',
      queryParameters: &lt;String,dynamic&gt;{'cn': 'iPhone_11', 'qt': '20', 'ct': 'Delhi'});
  }
  </code></pre>
