Eliza chat is a dart implementation of the ELIZA chatbot designed by Joseph Weizenbaum, in the sixties. ELIZA was one of the first chatbots that ever existed. This is a tribute to that wonderfull work that was well ahead of its time. The code for this package is based on the python version created by Wade Brainerd (https://github.com/wadetb/eliza)

To process the user its question, use the processInput() method. This method returns a String? value:

eliza.processInput(input);

processInput() CAN return a null value. If the user types "bye", "goodbye" or "quit", Eliza knows you want to terminate the conversation and will return a null value instead. By checking for a null value you can get confirmation that Eliza received the stop command and you get ask for a final sentence. The getFinal method returns a String value:

eliza.getFinal();
