How to change iPhone deployment target

Question

I have updated flutter today also with Xcode and I'm getting an error when trying to run my app on IOS

warning: The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 7.0, but the range of supported deployment target versions is 8.0 to 13.4.99. (in target 'gRPC-C++-gRPCCertificates-Cpp' from project 'Pods')

...

When I go to a runner from Xcode I can only change it to min version 8

Flutter doctor result

So how can I change the iPhone deployment target to a higher version in flutter?

UPDATE

Updating the android studio gets rid of the error.

Solution

If you changed Deployment Target in your Xcode project, open ios/Flutter/AppframeworkInfo.plist in your Flutter app and update the MinimumOSVersion value to match.

MinimumOSVersion section change the OSVersion to anything more than 8.0 (better to try the same project version).
