并且我希望显示相同“服务标记”的所有“服务级别描述”
这就是我所做的。 我的输出
所以你可以看到我得到了所有我需要的，但是你可以看到我只得到了来自'service leveldescription'的最后一个值，而不是所有'service leveldescription'
那么我如何在显示所有的“服务级别描述”时做到这一点呢？？
我的代码！！

我可以看到您有一个想要显示的数组，对于当前代码，您只访问了一个索引([index][“ServiceLevelDescription”])，这就是为什么您只显示了一个结果。
您可以创建一个负责填充数组的新函数。 然后将entitlements数组属性传递给该函数-类似于-[index][“entitlements”]
renderServiceLevelDescription(entitlementsArray) {
return Row(children: entitlementsArray.map((entitlement) =>
Flexible(
child: Text(entitlement.serviceLevelDescription), //You can edit this / style as you like
)
).toList());
}
然后你更新你的卡代码来调用这个！
希望这能有所帮助:）
