  1. PrintResult resultListener
)
override

打开本地钱箱 @param resultListener 钱箱开启情况，接口可执行后具体到调用打印机时的异常 @throws SdkException 接口实现情况，除商米打印机外目前接口返回不支持异常

Implementation

@override
Future<void> open(PrintResult resultListener) async {
  var transRes = await _myPlugin.open();
  var code = transRes[ParamConstants.CODE] as int?;
  var msg = transRes[ParamConstants.MSG] as String?;
  resultListener.onResult(code, msg);
}
