Flutter The plugin "xxx" requires a higher minimum iOS deployment version than..

flutter 开发，安装了插件，在运行 iOS 的时候报错：

Error: The plugin "mobile_scanner" requires a higher minimum iOS deployment version than your application is targeting. To build, increase your application's deployment target to at least 15.5.0 as described at https://flutter.dev/to/ios-deploy

找到 ios/Podfile 在顶部找到 platform 配置，打开修改它的版本。

# Uncomment this line to define a global platform for your project
platform :ios, '15.5.0'

然后重新运行即可！！如果遇到报错，可以参考这篇 # Flutter iOS 清除所有缓存。
