Flutter installation

I was installing flutter on my Mac M1. When I reach "Xcode command-line tools" step, I run the code : sudo xcodebuild -runFirstLaunch However this message always interrupted my installation:

"objc[983]: Class AMSupportURLConnectionDelegate is implemented in both /usr/lib/libamsupport.dylib (0x1e7217130) and /Library/Apple/System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice (0x1087982c8). One of the two will be used. Which one is undefined.

objc[983]: Class AMSupportURLSession is implemented in both /usr/lib/libamsupport.dylib (0x1e7217180) and /Library/Apple/System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice (0x108798318). One of the two will be used. Which one is undefined."

As a new user to Mac, Could anyone help please ?

Flutter is not a framework of Apple's. You would get a better chance to get better responses sooner if you visit the supporting site or a community site of it.

Someone in the Flutter community should be able to help you. Take a look at https://flutter.dev/community. Towards the bottom are links to various online Flutter resources.
