Decoder class

The Decoder class is responsible for orchestrating the entire scraping process for an NFE.

It performs the following tasks in sequence:

  1. Constructs the actual URL to be scraped using the URLBuilder.
  2. Fetches the HTML content of the constructed URL using the HTTPClient.
  3. Determines the state from the provided URL using the URLStateExtractor.
  4. Delegates the scraping process to the appropriate scraper via ScraperFactory.
  5. Returns the scraped NFE object.

Example usage:

var decoder = Decoder('some_nfe_url');
var nfe = await decoder.scrapeNfe();
print(nfe);

Note: The URLs provided in the example at the bottom are typical NFE URLs from the RS state.
