overflow at the bottom of the Get.defaultDialog() when the keyboard is open

I am using Get.defaultDialog() with a ListView.Builder and a TextformField() at the bottom of the dialog. The issue is whenever I open the keyboard, The bottom of the dialog box is getting overflowed.

I have tried various ways, But nothing is working for me.

One of the solutions I have tried

Other solutions that I tried are all similar to the above one.

If I give double.maxFinite then the dialog box covers the whole screen. I don't want that to happen.

What I want to achieve is, The height should not exceed the content of the dialog.

This is My Code for dialog() :

    void cancelTask() {
    RxInt selectedreason = 0.obs;
    String cancelReason = kCancelReasonList[0].name;
    TextEditingController cancelReasonController = TextEditingController();
    Get.defaultDialog(
      title: kLanguageList!.value.clearTask,
      titleStyle: TextStyle(
        color: kBlack,
        fontSize: kTextScaleFactor * 18,
        fontWeight: FontWeight.bold,
      ),
      textConfirm: kLanguageList!.value.ok,
      confirmTextColor: kBlack,
      textCancel: kLanguageList!.value.cancel,
      cancelTextColor: kOrange,
      buttonColor: Colors.transparent,
      contentPadding: EdgeInsets.symmetric(
          vertical: kWidth * 0.02, horizontal: kWidth * 0.02),
      onConfirm: () {},
      content: SingleChildScrollView(
        child: Obx(
          () => AnimatedContainer(
            duration: selectedreason.value != 3
                ? const Duration(seconds: 1)
                : const Duration(milliseconds: 500),
            width: kWidth * 0.7,
            height:
                selectedreason.value != 3 ? kHeight * 0.285 : kHeight * 0.37,
            child: Column(
              mainAxisAlignment: MainAxisAlignment.start,
              crossAxisAlignment: CrossAxisAlignment.start,
              children: [
                ListView.builder(
                  shrinkWrap: true,
                  itemCount: kCancelReasonList.length,
                  itemBuilder: (context, index) {
                    return RadioListTile(
                      toggleable: true,

                        boldText: false,
                      ),
                      value: index,
                      groupValue: selectedreason.value,
                      onChanged: (int? reason) {
