我已经被Flutter核心的构建错误困扰了好几天。这是iOS构建，到目前为止还没有尝试过Android，因为如果我无法使iOS运行起来就没有关系 :)

我尝试了flutter的不同通道(master, dev和stable)。 我尽可能更新了插件。 我执行了flutter clean，删除了pubspec.lock、podfile.lock、pods和DerivedData等。

我正在定制Flutter_sound，但没有更改任何依赖项。 运行最新的7.7.0 + 1版本。
在此示例中，我已添加firebase_core：0.7.0，尝试过未添加它的情况，但是只有与此完全匹配的配置为0.7.0，否则会出现依赖项不匹配。

我试过稳定版和开发版。
有任何想法吗？我真的卡住了。
