This code for making a POST as multipart/form-data works well, but whan a body field contains characters such as "é" "à" "ç" it throws this exception on backend on Angel Framework

Future<RestResponseGeneric<T>> uploadFiles(
    String apiEndPoint,
    List<File> files, {
    String topNode,
    Map<String, String> headers,
    Map<String, dynamic> body,
    Map<String, String> queryParameters,
    String basePath,
    String protocol,
    String hosting,
    int hostPort,
  }) async {
    try {
      var url = uri(
        apiEndPoint,
        queryParameters: queryParameters,
        protocol: protocol,
        host: hosting,
        port: hostPort,
        basePath: basePath,
      );

      var headersDefault = {    
         'Accept': 'application/json',      
      };
      var request = http.MultipartRequest('POST', url);

      if (headers != null) {
        request.headers.addAll(headers);
      } else {
        request.headers.addAll(headersDefault);
      }

      if (body != null) {
        request.fields['data'] = jsonEncode(body);
      }
      //&& files is File
      if (files != null) {
        var reader = FileReader();
        for (var file in files) {
          reader.readAsArrayBuffer(file);
          await reader.onLoadEnd.first;
          request.files.add(await http.MultipartFile.fromBytes('file[]', reader.result,
              contentType: MediaType('application', 'octet-stream'), filename: file.name));
        }
      } else {
        throw Exception('RestClientGeneric@uploadFiles files cannot be null');
      }

      //fields.forEach((k, v) => request.fields[k] = v);
      var streamedResponse = await request.send();
      var resp = await http.Response.fromStream(streamedResponse);
      var respJson = jsonDecode(resp.body);

      return RestResponseGeneric<T>(
        headers: resp.headers,
        data: respJson,
        message: 'Sucesso',
        status: RestStatus.SUCCESS,
        statusCode: 200,
      );
    } catch (e, stacktrace) {
      print('RestClientGeneric@uploadFiles exception: ${e} stacktrace: ${stacktrace}');
      return RestResponseGeneric(message: 'Erro ${e}', status: RestStatus.DANGER, statusCode: 400);
    }
  }
