Question

我想要滚动查看，但它不起作用。我将SingleChildScrollView放在Align内，并将Align放在Stack内，然后我把SingleChildScrollView Column内，

这是列表不起作用的原因吗？？？抱歉，解释不清楚?

这是代码：

Align(
                    alignment: Alignment.topCenter,
                    child: Container(
                      child: SingleChildScrollView(
                        child: Column(
                          children: <Widget>[
                            Container(
                              decoration : BoxDecoration(
                                //color: Colors.pink
                              ),
                              child: Padding(
                                padding: const EdgeInsets.only(right : 12.0),
                                child: Text('رقمك السري',
                                  style: TextStyle(
