title: Send parameters using RNFetchBlob.fetch
body: <p>I am trying to send data to a POST api but I can't figure out what's the correct syntax, I am using this:</p>
  
  <pre><code>RNFetchBlob.fetch(
      'POST',
      'htttp://www.myserver.com/api/login',
      { 'Content-Type': 'application/json'}
  )
  .then(response =&gt; {
      console.log(response.json());
  })
