CI/CD Codemagic - (Flutter ios) Packages are not supported when using legacy build locations, but the current project has them enabled

Question

I am trying to build my flutter app using codemagic, but every time I got this error

xcodebuild: error: Could not resolve package dependencies: Packages are not supported when using legacy build locations, but the current project has them enabled. Command: xcrun xcodebuild -list".

I know how to solve it from Xcode but in Codemagic CI/CD I cant use Xcode, is there any solution?

here is the log
