Creating XCode build target fails

[mitryp]

When I run dart run flutter_flavorizr to create a new flavor, I get this error during the ios:buildTargets task.
It has already occurred for me in the past, but I cannot recall how I avoided it.

It appears that the newly created build target has a minimum iOS target version of 12, no matter what version is configured in other targets, and if they are different, it breaks itself?

I would appreciate any insights on how to fix this.

flutter_flavorizr version: 2.3.1

UPD: A workaround is to сhangе all deployment targets to 12.0 first, run the command, and change the targets back

@mitryp This workaround totally worked for me as well. Thanks a lot for sharing it! Appreciate it 🙌

[mitryp]

In the current version, this does not appear to crash the package, however, it still generates all flavors with the iOS version 12.0, even when regenerating flavors that were already set to another iOS version.
