title: How to get response header in react native android?
body: <p>Hello i want to get response header after fetch POST request. I tried to debug to see what inside <code>response</code> with <code>console.log(response)</code>. I can get response bodies from <code>responseData</code> but i have no idea how to get the header. I want to get both header and the body. Please help. thanks:)</p>
  
  <p>Here's the example what i've done:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>   fetch(URL_REGISTER, {
        method: 'POST',
        body: formData
      })
        .then((response) =&gt; response.json())
        .then((responseData) =&gt; {
          if(responseData.success == 1){
            this.setState({
              message1: responseData.msg,
            });
          }
          else{
            this.setState({
              message1: responseData.msg,
            });
          }
        })
        .done();
      }, </code></pre>
  </div>
  </div>
  </p>
