ios - iOS 部署目标 'IPHONEOS_DEPLOYMENT_TARGET' 设置为 8.0，在 Flutter 中如何更改最小 IOS Deploying Target

Question

我在项目中将所有内容都更改为 9.0，但我在很多 pod 中都遇到了同样的错误。
我尝试做很多不同的事情，但没有任何效果。有谁知道我该如何解决这个问题？

9.0 to 14.0.99. (in target 'gRPC-C++-gRPCCertificates-Cpp' from project 'Pods')

对我有用的是@raffaelli-l-c 和@arhan-reddy-busam 答案的组合。
确保执行以下操作:

设置 MinimumOSVersion到 ios/Flutter/AppFrameworkInfo.plist 中的 9.0

确保取消注释 platform :ios, '9.0'在 ios/Podfile

确保 ios/Podfile包含以下安装后脚本:

    post_install do |installer|
      installer.pods_project.targets.each do |target|
        flutter_additional_ios_build_settings(target)
        target.build_configurations.each do |config|
          config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
        end
      end
    end

在进行生产构建时，以下例程对我有用:

    flutter clean \
        && rm ios/Podfile.lock pubspec.lock \
        && rm -rf ios/Pods ios/Runner.xcworkspace \
        && flutter build ios --build-name=1.0.0 --build-number=1 --release --dart-define=MY_APP_ENV=prod
