Error with File in Form Data

[rodydavis]

The other request goes through fine, but when I reach this bit of code it throws an error.

FormData formData = new FormData.from({
        "fileData": new UploadFileInfo(
            _uploadFile, basename(_uploadFile.path))
      });

Example

  void uploadVideo(BuildContext context, File _uploadFile) async {
    final _name = "Test Video Here";
    final _description = "This is a test description";
    if (_controller == null) {
      globals.Utility
          .showAlertPopup(context, "Info", "Video Required for Upload!");
    } else {
      final _ks = await globals.Utility.getKalturaSession();
      String _token = "";
      //  Add Video
      await http
          .get(
              'https://www.kaltura.com/api_v3/service/uploadtoken/action/add?ks=$_ks&format=1')
          .then((response) {
        Map<String, dynamic> _json = json.decode(response.body);
        _token = _json['id'].toString();
        print('"Token: $_token');
      });

      //  Upload Video
      String _url =
          "https://www.kaltura.com/api_v3/service/uploadtoken/action/upload?ks=$_ks&format=1&uploadTokenId=$_token&resume=false&finalChunk=true&resumeAt=-1";
      print("Path: " + _uploadFile.uri.toString());
      
      Dio dio = new Dio();
      Response response;
      FormData formData = new FormData.from({
        "fileData": new UploadFileInfo(
            _uploadFile, basename(_uploadFile.path))
      });
      response = await dio.post(_url, data: formData);
      print("RESPONSE: " + response.data.toString());

      //  Update Video Info (Name, Desctiption, Tags)
      var _formName = Uri.encodeQueryComponent(r'mediaEntry[name]');
      var _formDesription =
          Uri.encodeQueryComponent(r'mediaEntry[description]');
      var _formTags = Uri.encodeQueryComponent(r'mediaEntry[tags]');
      var _formType = Uri.encodeQueryComponent(r'mediaEntry[mediaType]');
      await http
          .get(
              'https://www.kaltura.com/api_v3/service/media/action/addFromUploadedFile?ks=$_ks&format=1&$_formTags=${globals.userCompanyID}&$_formName=$_name&$_formDesription=$_description&uploadTokenId=$_token&$_formType=1')
          .then((response) {
        print('Updated Info...');
        Map<String, dynamic> _json = json.decode(response.body);
        //  Verify Upload
        globals.videoID = "" + _json["id"].toString();

        if (globals.videoID.length > 1) {
          globals.Utility
              .showAlertPopup(context, "Info",
                  "The video you just uploaded will be avalible in 'Videos' when it finishes processing.")
              .then((onValue) {
            Navigator.pop(context);
          });
        } else {
          globals.Utility
              .showAlertPopup(context, "Info",
                  "There was an error uploading the video, please try again later.")
              .then((onValue) {
            Navigator.pop(context);
          });
        }
      });
    }
  }

1. update to version >=0.0.12
2. update your code :

FormData formData = new FormData.from(<String, dynamic>{
       ...
 });

change is "<String, dynamic>"

@phuquy2114 What is _formData['audio_file']? UploadFileInfo( File file) file must with right path(got with path_provider package).

[phuquy2114]

@wendux What is _formData['audio_file']? -> It's an audio file.
UploadFileInfo( File file) file must with right path(got with path_provider package) -> Yes, that is right
