@jerinho Unfortunately you cannot symlink a react native package. This is a problem with the metro bundler and you can follow the issue here: facebook/metro#1

thank you. but then yarn should not loads packages into node_modules directory. just like how the default "outdated" react-native-create-library works. please kindly let me know if anybody get different result
