The dart:io library in Dart is like a set of tools that lets your program interact with the outside world, especially when it comes to input and output. Here's a simple explanation:
Input and Output: dart:io helps your program read information from the user (like keyboard input) and write information to the screen (like printing messages).
File Operations: If your program needs to work with files, such as reading from or writing to them, dart:io provides tools for these file-related tasks.
Directory Operations: It helps your program manage directories, which are like folders that contain files.
Networking: If your program needs to connect to the internet, make requests to servers, or listen for incoming connections, dart:io has tools for networking tasks.
