Hi Durga,

I'm not sure how your question relates to Flutter: are you trying to upload an image using a Flutter API and it's not working?

We'd probably need to know more details about what you're trying to do before we can help you: what classes/methods are you using to send the image, how did you create/load the image, etc.

We're not really PHP experts, so if the problem is on that side, you're probably better off asking on a PHP list.

Thanks for reaching out!

Sounds like you want to submit an HTTP POST, containing binary data as the body.

I haven't tried this, but I think you can try something like this:

var httpClient = new HttpClient();

var request = await httpClient.postUrl(Uri.parse('http://your.server/upload.php'));

request.headers.contentType = new ContentType("image", "jpeg");  // or whatever MIME type for your image

request.add( ***a List<int> of the data for your image*** );

var response = await request.close();

You can read more at these API docs:

https://docs.flutter.io/flutter/dart-io/HttpClient/postUrl.html

https://docs.flutter.io/flutter/dart-io/HttpClientRequest-class.html

If you have further issues, we can recommend Stack Overflow as a really good place to post these kinds of "HOWTO" questions.

Hope that helps!
