title: How do you remove the "XMLHttpRequest error" in Flutter? (Django backend, Flutter frontend)
body: <p>I'm having trouble connecting my Django backend to my Flutter frontend on web.I have not tested on Android or iOS yet.</p>
  <p>I want to be able to do an API call and have it return a response that I can convert to a json. However it's been throwing errors no matter what I've tried. I've tried converting it into an https request with no avail.</p>
  <p>If anyone needs anything on the Django side please let me know</p>
  <p>This is what the error looks like:</p>
  <pre><code>Error: XMLHttpRequest error.

  <p>And this is a code snippet</p>

  var url2 = 'https://0.0.0.0:8809/test/';
                try{

                catch(exception){

                }
  
              },

  <p>I had it print out the error.</p>
