This project is a Flutter AI Voice Assistant via ChatGPT by OpenAI.

This project requires a valid session token from ChatGPT to access its unofficial REST API , speech_to_text and flutter_tts

*Sometimes slow to respond, mostly due to excessive use of ChatGPT

        if (result.finalResult) {
          _buildSubmit(result.recognizedWords);
        }
      },

    var input = prompt;
    Future.delayed(const Duration(milliseconds: 50)).then((_) => _scrollDown());
    var newMessage = await _api.sendMessage(
      input,
      conversationId: _conversationId,
      parentMessageId: _parentMessageId,
    );
    setState(() {
      _conversationId = newMessage.conversationId;
      _parentMessageId = newMessage.messageId;
      isLoading = false;
      _messages.add(
        ChatMessage(
          text: newMessage.message,
          chatMessageType: ChatMessageType.bot,
        ),
      );
      tts.speak(newMessage.message);
    });
    Future.delayed(const Duration(milliseconds: 50)).then((_) => _scrollDown());
  }
