Flutter IPHONEOS_DEPLOYMENT_TARGET is set to 8.0

修改 ios 目录下的 Podfile 文件

将底部的代码

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
end

替换成即可

post_install do |installer|
  installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
          config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '10.0'
      end
      flutter_additional_ios_build_settings(target)
  end
end

首先我这里的目标是 iOS 10.0，自行更改

将 ios/Flutter/AppFrameworkInfo.plist 的 MinimumOSversion 设置为 10.0

在Xcode中，将 Runner-> Project-> Runner 上的iOS Deployment Target 设置为 10.0

在Xcode中，将 Runner-> Targets-> Runner 中的 Deployment Info 设置为 iOS 10.0

取消注释 ios/Podfile 中的 #platform：iOS，'9.0' 改至 #platform：iOS，'10.0' 行
