Flutter Cocoapods兼容性错误-运行pod安装时出错

在这里和Github上都有很多类似的问题，但没有一个解决方案适合我。我一直在为这个错误绞尽脑汁，如果你有任何线索，请帮忙

在运行我的应用程序时，使用firebase身份验证，这就是我得到的

    [!] CocoaPods could not find compatible versions for pod "cloud_firestore":

    Specs satisfying the `cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`)` dependency were found, but they required a higher minimum deployment target.

[！]CocoaPods找不到pod“cloud\u firestore”的兼容版本：
在Podfile中：
cloud\u firestore（来自`.symlinks/plugins/cloud\u firestore/ios`）
找到了满足“cloud\u firestore（来自`.symlinks/plugins/cloud\u firestore/ios`）”依赖关系的规范，但它们需要更高的最低部署目标。

运行pod安装时出错
在iPhone 12上启动应用程序时出错。

我试着删除Podfile，取消Podfile中“version:'9.0'”的注释，flift clean，所有的东西都没用。我到底做错了什么？

如中所述（应该更突出显示），FlatterFire支持10或更高的iOS部署目标，符合底层firebase iOS sdk的要求。

解决方案是按照说明操作，并将部署目标设置为10

更改后，不要忘记运行
