我正在使用Flutter开发移动应用程序。老实说，我是Flutter的新手，也不熟悉IOS开发。我将Android Studio用作开发的IDE。现在，我正在尝试在运行以下命令的IOS模拟器上运行我的应用程序。
flutter run
当我这样做时，出现以下错误。
Error output from CocoaPods:
↳
[!] Automatically assigning platform `iOS` with version `8.0` on target `Runner` because no platform was specified. Please specify a platform for this target in your Podfile. See
`https://guides.cocoapods.org/syntax/podfile.html#platform`.
Error running pod install

我检查了链接中提到的链接，这对我不是很有帮助。我必须修改项目中的哪些文件以修复错误？我必须更改哪些设置？
我尝试在Podfile中取消注释此行“ platform：ios，'9.0'”。我仍然收到以下错误。
Launching lib/main.dart on iPhone 11 Pro Max in debug mode...

在您的Ios文件中，您将找到一个名为Podfile的文件，请打开该文件，并在文件的最顶部看到两行与此相似的行。
# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'
取消第二行的注释，看看是否可以解决您的问题。（只是取消注释您的行，请勿将我的行复制到文件中，因为可能会有所不同）让我知道
