title: http api request with captured fingerprint data
body: <p>Am building a platform to replace making use of secret pins to authenticate user's permission. Would love to know how I can make Http request with captured fingerprint data in a flutter to return a response in updating a UI.</p>
  
  <pre><code>url = 'localhost/trix/sand_box/pay';
  
  FingerData = User.ScannedPrint;
  
  Future&lt;Pay&gt; async {
      Pay pay = await http.post(url: url, body = FingerData, header = 
                'application/json');
  }
  </code></pre>
