title: Flutter Dart - How to send a Post Request using HttpClient()
body: <p>I am trying to send a Post request to my server using <code>HttpClient</code> but I am not sure where to actually set the payload and headers that need to be sent.</p>
  
  <pre><code>    var client = new HttpClient();
      client.post(host, port, path);
  </code></pre>
  
  <p><code>client.post(host, port, path)</code>  has only 3 arguments so how do I set the payload to be sent?</p>
  
  <p>Thanks in advance</p>
