如何在 ListView.Builder 中右对齐卡片中的行？

Question

我在 ListView.Builder 中对齐卡片末尾的行时遇到问题。当我申请 mainAxisAlignment: MainAxisAlignment.end 它不会像我想要的那样进入卡片的右侧。它走的正确距离因数据之前的长度而异。我究竟做错了什么？欢迎任何建议！谢谢！

这就是它的样子。我希望美元金额一直向右。

这是 ListView.Builder 的代码

              return ListView.builder(
                itemCount: transaction.length,
                shrinkWrap: true,
                itemBuilder: (context, index) {
                  return Padding(
                    padding: EdgeInsets.symmetric(vertical: 1.0, horizontal: 4.0),
                    child: Card(
                      color: (index % 2 == 0) ? greycolor : Colors.white,
                      child: Container(
                          height: 60,
                          child: Row(
                            children: <Widget>[
                              Expanded(
                                flex: 1,
                                child: Column(
                                  mainAxisAlignment: MainAxisAlignment.center,
                                children: [
                                  Container(
                                    margin: EdgeInsets.only(left: 5, top: 13),
                                    child: AutoSizeText(transaction[index].date,
                                        maxLines: 1,

                                        textAlign: TextAlign.left),
                                  ),
                                ],
                              ),),
                              Flexible(

只需将 Flexible 替换为 Expanded

Flexible 只占用所需空间，Expanded 占用所有可用空间
