Not able to create column and row in flutter listview

I am beginner to flutter and I am trying to add the new column, first one is default visible and the second one is visible (this is needs to be done, I have already have the code but before adding things, I am trying to set it up) by the action. So I have updated code with columns, but if I do that, all the cards are displaying as empty, not sure where I am making issue

  @override
  Widget build(BuildContext context) {
    var img = widget.data['password'];
    return Card(
      // borderOnForeground: true,
      color: const Color.fromARGB(255, 55, 55, 55),
      shape: RoundedRectangleBorder(
        borderRadius: BorderRadius.circular(10.0),
        side: const BorderSide(
          color: Color.fromARGB(255, 60, 60, 60),
          width: 1.0,
        ),
      ),
      child: ClipPath(
        clipper: ShapeBorderClipper(
          shape: RoundedRectangleBorder(
            borderRadius: BorderRadius.circular(15),
          ),
        ),
        child: Container(
          height: 150,
          decoration: const BoxDecoration(
            border: Border(
              left: BorderSide(
                  color: Color.fromARGB(255, 143, 175, 112), width: 10),
            ),
            color: Color.fromARGB(255, 242, 241, 241),
          ),
          padding: const EdgeInsets.all(10.0),
          // alignment: Alignment.centerLeft,
          child: Row(
            children: [
              Expanded(
                flex: 4,
                child: Container(
                    // child: Column( //!!!!!!!!!!!!!!!!!If I add this line of code to make two columns it is displaying only the above container
                    children: [
