Flutter ChatGPT API

This package is a Flutter/Dart API around ChatGPT by OpenAI.

This package requires a valid session token from ChatGPT to access its unofficial REST API.

This version have been updated to use Puppeteer to log in to ChatGPT and extract the Cloudflare cf_clearance cookie and OpenAI session token. 🔥 Thanks to Node.js ChatGPT API (unofficial)

       clearanceToken: CLEARANCE_TOKEN,
     );

setState(() {
  _messages.add(
    ChatMessage(
      text: _textController.text,

var newMessage = await _api.sendMessage(
  input,
  conversationId: _conversationId,
  parentMessageId: _parentMessageId,
);

setState(() {
  _conversationId = newMessage.conversationId;
  _parentMessageId = newMessage.messageId;
  isLoading = false;
  _messages.add(

4. Create these files and add your session token to run the tests and example respectively:

Copy the value for __Secure-next-auth.session-token and save it to your environment.example/lib/session_token.dart

Copy the value for cf_clearance and save it to your environment. example/lib/clearance_token.dart

Should look something like this:

const SESSION_TOKEN = '__Secure-next-auth.session-token from https://chat.openai.com/chat';

const CLEARANCE_TOKEN = 'cf_clearance token from https://chat.openai.com/chat';
