Flutter 当键盘在抖动中打开时，如何才能看到包装在SingleChildScrollView中的列中的最后一个小工具

Row(
              mainAxisAlignment: MainAxisAlignment.spaceBetween,
              children: [
                const Text(
                  'Discount (%) :',
                  style: TextStyle(fontSize: 14),
                ),
                Container(
                  width: 40,
                  height: 30,
                  decoration: BoxDecoration(
                      color: Colors.grey.shade200,
                      border: const Border.fromBorderSide(BorderSide.none),
                      borderRadius: BorderRadius.circular(10)),
                  child: Center(
                    child: TextField(
                      onChanged: (text) {
                        getDiscountedAmount(text);
                      },
                      cursorHeight: 18,
                      keyboardType: TextInputType.number,
                      controller: discountController,
                      decoration: const InputDecoration(
                        floatingLabelBehavior: FloatingLabelBehavior.never,
                        border: InputBorder.none,
                        contentPadding:
                            EdgeInsets.only(bottom: 12, right: 2),
                        labelText: '    0',
                        labelStyle: TextStyle(
                          fontSize: 14,
                        ),
                      ),
                      textAlign: TextAlign.center,
                      style: const TextStyle(
                        fontSize: 14,
                      ),
                    ),
                  ),
                ),
              ],
            ),

This is how screen looks when keyboard is opened.I有用SingleChildScrollView包装的列.Column包含作为最后一个小部件的TextField.当我点击文本字段时，默认情况下，我的键盘会与文本字段重叠.我看不到文本字段中的输入是什么.即使在键盘打开的情况下，我也希望看到Textfield. 如何在Flutter 翼中做到这一点？请给我带路.先谢谢你.

我希望屏幕滚动起来，文本字段应该是可见的，即使键盘是打开的.

This discount row has a textfield. when i click on it, keyboard appears and textfield goes behind the keyboard. i want to whole screen to slide up to see the textfield even when the keyboard is opened.个
