Example project

Here you will find two different examples:

1. Simple example, that you can run with dart run lib/main.dart --simple command from the example folder.

2. A modified http package example that uses the functional_status_codes library to handle HTTP status codes in a functional way. It uses the Google Books API to search for books and parses the response from the API to print the number of books found.

First, it creates a URL for the API request and sends a GET request to the server. It then checks if the status code of the response is a valid HTTP status code. If it is, it checks if the status code is a success status code (in the range 200-299). If it is, it converts the status code to a StatusCode object from the functional_status_codes library, and uses the maybeMap method to determine if the status code is a 201 (Created) or a 200 (OK). If it is a 201, it prints a message and returns the status code. If it is a 200, it decodes the JSON response, gets the total number of books found, and prints the number of books. If the status code is not a 201 or a 200, it prints a message and returns the status code. If the status code is not a success status code, it prints an error message and returns the status code. If the status code is not a valid HTTP status code, it returns null.
