Need help to build custom widget in flutter

Question

Hey I try to create a custom widget like this, where I can change the text in the bottom part of the card.

I already create the shape but I have no idea on how to place Text('Aktif'), I tried using Stack or Column but none works, any Idea?

Here is my code:

@override
  Widget build(BuildContext context) {
    return Stack(
      children: [
        Card(
          shape: CardShape(),
          elevation: 18,
          shadowColor: const Color.fromRGBO(51, 0, 0, 0.1),
          color: CustomStyle.primaryRed,
          child: Container(
            decoration: BoxDecoration(
                color: CustomStyle.white,
                border: Border.all(color: CustomStyle.primaryRed),
                borderRadius: BorderRadius.circular(8)),
            padding: const EdgeInsets.symmetric(vertical: 8),
            child: ListTile(
              title: const Text('Rumah Tanggerang'),
              subtitle: const Text('Primary - 1234567890'),
              trailing: Row(
                mainAxisAlignment: MainAxisAlignment.end,
                mainAxisSize: MainAxisSize.min,
                children: <Widget>[
                  Text(
                    'DEFAULT',
                  ),
                  myPopMenu()
                ],
              ),
            ),
          ),
        ),
        Positioned(left: 10, bottom: 0, child: Text('Aktif'))
      ],
    );
  }

class CardShape extends ShapeBorder {
  const CardShape();

  final BorderSide _side = BorderSide.none;
  final BorderRadiusGeometry _borderRadius = BorderRadius.zero;

  @override
  EdgeInsetsGeometry get dimensions => EdgeInsets.all(_side.width);

  @override
  Path getInnerPath(
    Rect rect, {
    TextDirection? textDirection,
  }) {
    final Path path = Path();

    path.addRRect(
      _borderRadius.resolve(textDirection).toRRect(rect).deflate(_side.width),
    );

    return path;
  }

  @override
  Path getOuterPath(Rect rect, {TextDirection? textDirection}) {
    final Path path = Path();
    final RRect rrect = _borderRadius.resolve(textDirection).toRRect(rect);

    path.moveTo(0, 10);
    path.quadraticBezierTo(0, 0, 10, 0);
    path.lineTo(rrect.width - 10, 0);
    path.quadraticBezierTo(rrect.width, 0, rrect.width, 10);
    path.lineTo(rrect.width, rrect.height - 10);
    path.quadraticBezierTo(
        rrect.width, rrect.height, rrect.width - 10, rrect.height);
    path.lineTo(100, rrect.height);
    path.lineTo(80, rrect.height + 20);
    path.lineTo(10, rrect.height + 20);
    path.quadraticBezierTo(0, rrect.height + 20, 0, rrect.height + 10);

    return path;
  }

  @override
  void paint(Canvas canvas, Rect rect, {TextDirection? textDirection}) {}

  @override
  ShapeBorder scale(double t) => RoundedRectangleBorder(
        side: _side.scale(t),
        borderRadius: _borderRadius * t,
      );
}

could you also include the card code too?

Card widget can't used stack because the red container is already outside the Card element so to put the text you just can wrap Stack inside of a Column and put the Text widget without position this is the example that I've already did

class Test extends StatelessWidget {
  const Test({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: Container(
          decoration: const BoxDecoration(color: Colors.blue),
          child: Column(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: [
              Stack(
                children: [
                  Card(
                    shape: const CardShape(),
                    elevation: 18,
                    shadowColor: const Color.fromRGBO(51, 0, 0, 0.1),
                    color: Colors.red,
                    child: Container(
                      decoration: BoxDecoration(
                          color: Colors.white,
                          border: Border.all(color: Colors.red),
                          borderRadius: BorderRadius.circular(8)),
                      padding: const EdgeInsets.symmetric(vertical: 8),
                      child: ListTile(
                        title: const Text('Rumah Tanggerang'),
                        subtitle: const Text('Primary - 1234567890'),
                        trailing: Row(
                          mainAxisAlignment: MainAxisAlignment.end,
                          mainAxisSize: MainAxisSize.min,
                          children: const <Widget>[
                            Text(
                              'DEFAULT',
                            ),
                          ],
                        ),
                      ),
                    ),
                  ),
                ],
              ),
              const Padding(
                padding: EdgeInsets.only(
                  left: 30,
                ),
                child: Text(
                  'Aktif',
                  style: TextStyle(
                      color: Colors.white, fontWeight: FontWeight.w700),
                ),
              )
            ],
          ),
        ),
      ),
    );
  }
}

if you copy my code just made sure to change back the color you've used.
