How to get response from streamed response in flutter? [duplicate]

Question

I am developing an app using flutter and I am using http library to call the api I built.

and I want to make a multipart request to send files and it sends it as well but I can't receive any response from the server because the object returned is StreamResponse.

please tell me how to get the body of the response.

Code Snippet:

var request = http.MultipartRequest('POST', Uri.parse('$SERVER_URL/signup'));
    request.files.add(await http.MultipartFile.fromPath(
      'image',
      user.image,
      filename: 'image',
      contentType: MediaType('multipart/form-data', 'multipart/form-data'),
    ));



    StreamResponse x = await request.send();
    //get body of the response

Thanks,

Answer 1

Just use http.Response.fromStream()

import 'package:http/http.dart' as http;

var streamedResponse = await request.send();
var response = await http.Response.fromStream(streamedResponse);

Answer 2

StreamedResponse has a stream getter as you'd expect that delivers a stream of byte arrays.

Assuming that you want characters instead of bytes, push those through the appropriate character decoder - let's assume UTF-8.

You then might want all those joined into a single string, so we can use join. Giving you:

  print(await x.stream.transform(utf8.decoder).join());
