I am already using onValueReceived

void printValue() async {
    _services.forEach((service) {
      if (service.uuid.toString() == SERVICE_UUID) {
        service.characteristics.forEach((characteristic) {
          if (characteristic.uuid.toString() == CHARACTERISTIC_UUID) {
            characteristic.setNotifyValue(!characteristic.isNotifying);
            characteristic.onValueReceived.listen((data) {
              print(">>>>>>>>>>>>>>>>");
              if (utf8.decode(data).contains("Orient")) {
                String stream1 = utf8.decode(data);
                print(stream1);
              }
            });
          }
        });
      }
    });
  }

This is the function I which I using to print the values in the debug console
