In this example we can access any module of this package outside of App folder. suppose we are use the module of App>>Db>> file. first see the

This file are contain one function deleteData(). so how to use this file function outside the app folder?. that is very simple. help of package directory we can access this file function.


for example suppose is exist outside app folder. and this file imported package of (App>>Dd>>delete) module.
import App.Db.delete
Delete Data Function is used to access module of directory. so it is very important to define this file. this file may be empty but that are used to create package.
