在将Flutter升级到2.5.0后，无法在Android Studio中从iOS模拟器运行应用程序。

我无法在iOS模拟器上运行我的应用程序。在从Flutter 2.2.3升级到Flutter 2.5.0之后，我遇到了这个错误

我无法从Android Studio运行Flutter应用程序。但是，如果从Xcode打开项目，那么应用程序将在iOS模拟器中无问题地运行。

这里是错误/警告信息

我尝试了几个来自SO的解决方案，但都没有什么结果。我迄今为止尝试过的方法包括：

  1. flutter clean
  2. 删除podfile.lock。遵循此链接
  3. 在模拟器中删除应用程序

将此代码添加到您的Podfile中：

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'].to_f < 9.0
        config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
      end
    end
  end
end

您可以将9.0更改为您的项目的部署目标版本。
