//File handling is an important part of any programming language
//While programming, you might run into some sort of situation,
// where you need to work on a file stored at a specific location,
// maybe write something on it, read it or anything else. Dart supports
// working with files as well.
// In order to start working, first of all we need to import dart’s inbuilt
// io (input output) library.
// import 'dart:io';
// This library gives us access to a large number of classes, methods
// and properties which we can use to perform various operations. In
// current situation, we need to work with files, hence, we need to
// create an instance of the File class
