xmlhttprequest error flutter

this worked for me, I added the below header on the lambda function

return {
    statusCode: 200,
     headers: {
  "Access-Control-Allow-Origin": "*", // Required for CORS support to work
  "Access-Control-Allow-Credentials": true, // Required for cookies, authorization headers with HTTPS
  "Access-Control-Allow-Headers": "Origin,Content-Type,X-Amz-Date,Authorization,X-Api-Key,X-Amz-Security-Token,locale",
  "Access-Control-Allow-Methods": "POST, OPTIONS"
},
    body: JSON.stringify(item)
};

                                    // Get your local IP by ipconfig (command prompt)
// XAMPP Apache 2.4 httpd.conf:
&lt;Directory /&gt;
    Require local
    Require ip 192.168.0
&lt;/Directory&gt;
// Flutter side: add headers to async method:
var response = await http.get(Uri.parse(&quot;http://192.168.0.54/api.php&quot;),
  headers: {
    &quot;Accept&quot;: &quot;application/json&quot;,
    &quot;Access-Control-Allow-Origin&quot;: &quot;*&quot;
  });
// php side (api.php):
&lt;?php		// Modify header too
header('Content-Type: application/json');
header(&quot;Access-Control-Allow-Origin: *&quot;);		// CORS
header(&quot;Access-Control-Allow-Headers: Access-Control-Allow-Origin, Accept&quot;);
echo json_encode(['id' =&gt; '33', 'success' =&gt; 'OK']);
