dart - How to make HTTP request to In Flutter Web

Question

I was trying my hands on flutter web. I tried to connect a simple flutter web app I created to mysql database and localhost using the http package. However I dont get any data returned from the request method. When I tried to print out snaphot.error I got this: XMLHttpRequest error. I have this method in a FutureBuilder()

getMethod()async{
  String theUrl = 'https://localhost/fetchData.php';
  var res = await http.get(Uri.encodeFull(theUrl),headers: {"Accept":"application/json"});
  var responsBody = json.decode(res.body);
  print(responsBody);
  return responsBody;

}

You can also Add the code below to your php file like so:

<?php
require('connection.php');
header("Access-Control-Allow-Origin: *");
....
code goes here
....
?>

I Tried this on LocalHost and it worked.

NB: If you're using nodejs install the cors() package and use like

var express = require('express')
var app = express()
var cors = require('cors')

app.use(cors())

Check out the CORS package on npmjs
