我有底部溢出的像素抖动时显示键盘，我尝试了SingleChildSCrollView，仍然找不到解决办法。我的目标是使Get.defaultDialog滚动。
下面是我代码：

class AddCard extends StatelessWidget {
  final homeCtrl = Get.find<HomeController>();
  AddCard({super.key});

  @override
  Widget build(BuildContext context) {
    final icons = getIcons();
    var squareWidth = Get.width - 12.0.wp;
    return Container(
      width: squareWidth / 2,
      height: squareWidth / 2,
      margin: EdgeInsets.all(3.0.wp),
      child: InkWell(
        onTap: () async {
          await Get.defaultDialog(
              titlePadding: EdgeInsets.symmetric(vertical: 5.0.wp),
              radius: 5,
              title: 'Task Type',
              content: Form(
                key: homeCtrl.formKey,
                child: Column(
                  children: [
                    Padding(
                      padding: EdgeInsets.symmetric(horizontal: 3.0.wp),
                      child: TextFormField(
                        controller: homeCtrl.editCtrl,
                        decoration: const InputDecoration(
                          border: OutlineInputBorder(),
                          labelText: 'title',
                        ),
                        validator: (value) {
                          if (value == null || value.trim().isEmpty) {
                            return 'Please enter your task title';
                          }
                          return null;
                        },
                      ),
                    ),
                    Padding(
                      padding: EdgeInsets.symmetric(vertical: 5.0.wp),
                      child: Wrap(
                        spacing: 2.0.wp,
                        children: icons
                            .map((e) => Obx(() {
                                  final index = icons.indexOf(e);
                                  return ChoiceChip(
                                    selectedColor: Colors.grey[200],
                                    pressElevation: 0,
                                    backgroundColor: Colors.white,
                                    label: e,
                                    selected: homeCtrl.chipIndex.value == index,
                                    onSelected: (bool selected) {
                                      homeCtrl.chipIndex.value =
                                          selected ? index : 0;
                                    },
                                  );
                                }))
                            .toList(),
                      ),
                    ),
                    ElevatedButton(
                      style: ElevatedButton.styleFrom(
                        backgroundColor: blue,
                        shape: RoundedRectangleBorder(
                          borderRadius: BorderRadius.circular(20),
                        ),
                        minimumSize: const Size(150, 40),
                      ),
                      onPressed: () {
                        if (homeCtrl.formKey.currentState!.validate()) {
                          int icon =
                              icons[homeCtrl.chipIndex.value].icon!.codePoint;
                          String color =
                              icons[homeCtrl.chipIndex.value].color!.toHex();
                          var task = Task(
                            title: homeCtrl.editCtrl.text,
                            icon: icon,
                            color: color,
                          );
                        }
                      },
                      child: const Text("Confirm"),
                    ),
                  ],
                ),
              ));
        },
        child: DottedBorder(
            color: Colors.grey[400]!,
            dashPattern: const [8, 4],
            child: Center(
              child: Icon(
                Icons.add,
                size: 10.0.wp,
                color: Colors.grey,
              ),
            )),
      ),
    );
  }
}

产生错误的小部件是Get.defaultDialog（）。
