I have exactly the same problem on the web part.

I'm trying to find a solution on my side.

Okay I'm back with a solution

Already down to version 6.2.1 because apparently there is a typing error in the file stream
All execution must be in the same method, processing the file and sending the file, the web part of flutter is really very capricious, separated it is two methods would only lose the integrity of the result file by a phenomenon which surpasses me
I had to build a class interface to separate the web part and the app part since the web part is allergic to dart.io

Exemple my code for web :

`
import "package:http/http.dart" as http;
Future setFile(FilePickerResult? result, String typeUpload, String fileUrl) async {
try {

  // if file
  if (result != null && result.files.isNotEmpty && result.files.single.readStream != null) {
    
   // Uri address
    Uri uri = Uri.parse(_urlList.urlPostUploadFile);

    /// array post 
    Map<String, String> requestMap = {
      "cible": typeUpload,
    };

    /// prepare to request file
    /// read stream ??? WTF type File ???? baaa it works with this ;)
    http.ByteStream stream = http.ByteStream(result.files.single.readStream!.asBroadcastStream());

    /// Include multiparte file
    var request = http.MultipartRequest('POST', uri);
    request.fields.addAll(requestMap);
    request.files.add(http.MultipartFile(
      'file',
      stream,
      result.files.first.size,
      filename: result.files.first.name,
    ));

    /// Post file
    var response = await request.send();
    if (response.statusCode == 200) {
      /// Lecture des données - retour serveur
      String responseString = await response.stream.bytesToString();

      print("REPONSE : $responseString");

      /// Décodage des données json
      var jsonData = jsonDecode(responseString);
      _setInfo = CtrlUploadData.fromJson(jsonData);

      /// check code info
      if (_setInfo.returnCode != 0 && _setInfo.returnCode <= 8) {
        return false;
      } else {
        return true;
      }
    } else {
      return false;
    }
  } else {
    return false;
  }
} catch (ex) {
  return false;
}

`

We really need to make an effort to clarify and enter into a standardized convention, the backtracking in this part of the code has been numerous on my side and the doc is not at all in line with what is happening concretely.

I spent some time on this and made the effort to detail everything, I hope this will be taken into account in the next patch

Sorry but it's frustrating for me to see this error several times

in particular it is the typing problem of result.files.first.readStream which poses recurring problems.
More info on this and clear documentation would not be refused.

Sorry for my English, best regards

I would at least like to have a response from you before you close this thread ?!
Best regards
