无法为模拟器构建应用程序，但 flutter build ios 有效

Question

When I try to run my app from Android Studio, I get this error:

warning: The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set
to 8.0, but the range of supported deployment target versions is 9.0 to 15.0.99. (in target 'FMDB' from project 'Pods')

I'm also able to run this app in the same emulator from Xcode.

Here's my Flutter doctor:

Answer 1

Uncomment platform in PodFile and keep it as 12.0 or 11.0. Delete PodFile.lock and run pod install. Open wcworkspace in xcode and you will see a warning. Click on the warning and it would show an option to upgrade deployment target version. Click on apply. Close xcode. Now the flutter run for ios emulator from Android studio should work as expected.
