Size of app after using a package like (intl) in more than one package

I want to ask a question about for example if I want to use a package like flutter_screenutil I will need to add a package in pubspec for main and component_library and features will this affect the total size of the app or flutter can handle that and remove redundant duplication?

Dear @yousef_mo!

In general, it is a good practice to not duplicate the packages in multiple places as it takes a lot of effort to maintain the correct package versions when upgrading them. Although, that should not affect the size od the app.
