Implementation

Future<String?> uploadFile(String uploadUrl, File file) async {
  final fileName = file.path.split(Platform.pathSeparator).last;
  logger.logDebug.call("Uploading file: $fileName to $uploadUrl");
  try {
    final response = await _dio.post(
      uploadUrl,
      data: FormData.fromMap({
        "file": await MultipartFile.fromFile(file.path, filename: fileName),
      }),
      queryParameters: {"name": fileName},
    );
    if (response.statusCode == 201) {
      return response.data["browser_download_url"];
    }
  } on DioException catch (e) {
    logger.logErrorVerbose.call("Failed to upload file: $fileName");
    if (e.response != null) {
      if (e.response?.data is Map<String, dynamic>) {
        logger.logErrorVerbose.call(
          "Response : ${e.response?.data["message"]}",
        );
      } else {
        logger.logErrorVerbose.call("Response : ${e.response?.data}");
      }
    } else {
      logger.logErrorVerbose.call("Response : ${e.message}");
    }
  } catch (e) {
    logger.logErrorVerbose.call("$e");
  }
  return null;
