Not getting an error when opening a file. How to show a toast when there is no proper app for viewing the content using OpenFile.open in flutter?

Question

OpenFile.open is not showing error. Am trying to open an excel file, am not having a proper app for viewing that excel sheet. How can I show a toast message for this case.

OpenFile.open(file.path,
            type: "application/vnd.ms-excel",
            uti: "com.microsoft.excel.xls")
        .catchError((e, stackTrace) {
      print('hey error');
      print(e);
      return 
        DialogsService().showServerErrorMessageToast(
          "You may not have a proper app for viewing this content.");
    });
