Flutter Wrap 布局不会扩展到全部可用宽度

Question

我正在创建一个动态列表，它创建如下图所示的布局。但在较小的屏幕上，我在“已发布”文本和删除图标的行中出现像素溢出。为了解决这个问题，我将它们包装在一个Wrap小部件中，以便图标可以移动到新行。但由于某种原因，Wrap 小部件没有扩展到完全可用的水平宽度。
我想定位“已发布”文本并删除带有Spacer()中间或仅对齐的图标spacebetween，但我无法在小部件Spacer()中定位 aWrap并且spaceBetween对齐没有效果，因为文本和图标之间没有可用空间。

只需替换列交叉轴对齐即可拉伸：

...
                  child: Column(
                    crossAxisAlignment: CrossAxisAlignment.stretch, // !!!!!!! here
                    children: [
                      Row(
                        children: [
                          Text(
                            children[i].credentialSubject.documentName,
                            style:
                                Theme.of(context).textTheme.bodyText1,
                          ),
