Flutter：AVCapturePhotoOutput' 仅适用于 iOS 10.0 或更高版本答案

【问题标题】：Flutter: AVCapturePhotoOutput' is only available on iOS 10.0 or newerFlutter：AVCapturePhotoOutput' 仅适用于 iOS 10.0 或更高版本

【问题描述】：

由于我在稳定通道上升级了 Flutter，我无法在 IOS 模拟器上运行。这是更新 Flutter 时经常出现的错误，尽管我进行了研究，但我找不到任何解决方案。我尝试删除 Podfile.lock，更新 pod 并重新安装，更改频道并升级，但总是出现相同的错误。

我切换回master分支后遇到同样的问题，执行你提供的命令后仍然出现错误。
@HaifengZhang 我搬到了稳定频道（v1.17.0）。我想你已经执行了flutter clean，尝试在Xcode上清理构建文件夹-从你的flutter源文件夹中删除缓存
