flutter - 如何使文本字段输入保持垂直居中？

Question

我想在textFiled中放入一个Container。但是我发现输入内容不能在Container中保持垂直方向(高一点)，但是两个icons显示得很好。我的情况有解决办法吗？

Container(
                      width: ScreenAdapt.widthToDp(330),
                      height: ScreenAdapt.heightToDp(40),
                      alignment: Alignment.centerLeft,
                      child: TextField(
                        controller: inputController,
                        focusNode: focusNode,
                        style: MyTextStyle.level4,
                        keyboardType: TextInputType.number,
                        decoration: InputDecoration(
                          prefixIcon: MyIcon.SearchGreyIcon,
                          hintText: 'hint text here',
                          hintStyle: MyTextStyle.grey,
                          border: InputBorder.none,
                          suffixIcon: focusNode.hasFocus ? IconButton(
                            icon: MyIcon.CloseIcon,
                            onPressed: () => inputController.clear(),
                          ) : Container(),
                        ),
                      ),
                      decoration: BoxDecoration(
                        color: MyColor.MidGray,
                        borderRadius: MyStyle.CIRCULAR_BORDER_RADIUS,
                      ),
                    ),

试试这个@Assassin建议

InputDecoration(
        prefixIcon: MyIcon.SearchGreyIcon,
        hintText: 'hint text here',
        hintStyle: MyTextStyle.grey,
        border: InputBorder.none,
        filled: true,
        suffixIcon: focusNode.hasFocus
            ? IconButton(
                icon: MyIcon.CloseIcon,
                onPressed: () => inputController.clear(),
              )
            : Container(),
      )
