满足“firebase_admob”的规范，但在Flutter中需要更高的最小部署目标

使用 将 firebase_admob 更新到最新版本时firebase_admob: ^0.11.0+1，我的 Flutter 应用程序停止工作，可能是 firebase 的包之间存在冲突。我正在尝试为 iOS 构建一个应用程序，但由于 cocoapods，flutter 运行失败：

我只是将 firebase 系列的两个包更新到最新版本。我正在使用的包：

firebase_admob: ^0.11.0+1
firebase_crashlytics: ^0.4.0+1


这是输出 pod install --repo-update

Updating local specs repositories
CocoaPods 1.10.1 is available.

[!] CocoaPods could not find compatible versions for pod "firebase_admob":
In Podfile:
firebase_admob (from `.symlinks/plugins/firebase_admob/ios`)
Specs satisfying the `firebase_admob (from `.symlinks/plugins/firebase_admob/ios`)` dependency were found, but they required a higher minimum deployment target.
[!] Automatically assigning platform `iOS` with version `9.0` on target `Runner` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.


我的 iOS 设备有一些问题，但它在 android 上运行良好。我在安装 pod 时遇到错误

我已经使用 flutter dev & master 频道尝试过这个，并且遇到了同样的问题。我目前正在使用大师。我试过删除我的 Pods 文件夹并重新运行 pod install 但没有工作任何人

这是输出 flutter doctor -v
