I have to display a Card inside row. It is taking full space . When I have a column I set mainAxis It reduces the size

I want to achieve the same effect for All Plans Text field

Is there any attribute for doing the same if I only have a single TextView

My Code

GenericRow(
      padding: const EdgeInsets.symmetric(horizontal: 16, vertical: 8), // Padding around the row
      spacing: 16.0, // Space between cards
      useExpanded: true, // Ensures both cards expand fully
      children: [
        Card(
          color: Colors.deepOrange,
          shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(12)),
          child: Padding(
            padding: const EdgeInsets.all(16.0), // Adds spacing inside the Card
            child: Center(
              child: Text(
                "All Plans",
                style: TextStyle(
                  color: Colors.white,
                  fontSize: 18,
                  fontWeight: FontWeight.bold,
                ),
                textAlign: TextAlign.center,
              ),
            ),
          ),
        ),

        Card(
          color: Colors.green,
          shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(12)),
          child: Padding(
            padding: const EdgeInsets.all(16.0),
            child: Column(
              mainAxisSize: MainAxisSize.min,
              children: [
                Text("Card 2", style: TextStyle(color: Colors.white, fontSize: 18, fontWeight: FontWeight.bold)),
                SizedBox(height: 8),
                Text("This is the second card", style: TextStyle(color: Colors.white)),
              ],
            ),
          ),
        ),
      ],
    )

generic_row.dart

class GenericRow extends StatelessWidget {
  final List<Widget> children;
  final MainAxisAlignment mainAxisAlignment;
  final CrossAxisAlignment crossAxisAlignment;
  final double spacing;
  final EdgeInsets padding; // Padding around the row
  final bool useExpanded; // if set width will no effect on it

  const GenericRow({
    super.key,
    required this.children,
    this.mainAxisAlignment = MainAxisAlignment.center,
    this.crossAxisAlignment = CrossAxisAlignment.center,
    this.spacing = 0.0,
    this.padding = EdgeInsets.zero,
    this.useExpanded = true,
  });

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: padding,
      child: Row(
        mainAxisAlignment: mainAxisAlignment,
        crossAxisAlignment: crossAxisAlignment,
        children: [
          //TODO convert below for loop to mapping function
          for (int index = 0; index < children.length; index++) ...[
            ///Expanded(child: children[index]),
            if (useExpanded) Expanded(child: children[index]) else children[index],
            if (index < children.length - 1) SizedBox(width: spacing),
          ],
        ],
      ),
    );
  }
}

The first deepOrange Card Taking full height where as I don't want it to have full height.

Is there any field or attribute that work like mainAxisSize: MainAxisSize.min or I have to use IntrinsicHeight for it

I need to have a cleaner approach to do this that has less number of children and easily extendable.
