嘿，我试着创建一个自定义的小部件，像这样，在那里我可以改变卡片底部的文本。

我已经创建了形状，但我不知道如何放置Text('Aktif')，我尝试使用堆栈或列，但没有工作，任何想法？
下面是我的代码：

@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,
      );
}
