Future printTicket() async {
    String? isConnected = await BluetoothThermalPrinter.connectionStatus;
    if (isConnected == "true") {
      Listing bytes = await getTicket();
      // Listing bytes = utf8.encode("Hey, Printer!nnn");
      print(bytes);
      // ultimate consequence = await BluetoothThermalPrinter.writeBytes(bytes);
      ultimate consequence = await BluetoothThermalPrinter.writeText("hiya there");
      print("Print $consequence");
    } else {
      //Hadnle Not Linked Senario
    }
  }
