• Default support for the GPT-3.5-turbo model.
• Ability to use your own API service.
• Dynamic configuration options such as model, messages, and token limits.
• Allowing Users to Customize Message Sending Functionality

Installation

dependencies:
  your_chatbot_package: ^1.1.0

Usage

ChatBot provides an easy way to implement the ChatGPT API, allowing you to focus on more important matters. To get started, create a ChatController instance and provide it with the API key.

import 'package:chat_bot/controllers/chat_controller.dart';

final ChatController chatController = ChatController(
  apiKey: 'your-api-key-here',
);

Next, use our ChatBot widget, which requires the chatController instance

ChatBot(
  chatController: chatController,
),

And that's all!

Custom Configuration

Customize your ChatGptModel and other properties.

final ChatController chatController = ChatController(
  apiKey: 'your-api-key-here',
  params: ParamsChatBot(
    model: 'gpt-3.5-turbo',
    maxTokens: 150,
  )
);

And modify the style of the widgets as you wish.

ChatBot(
  chatController: chatController,
  customTypeIndicator: const LinearProgressIndicator(),
  styleInput: const ChatInputStyle(
    activeColor: Colors.red
  ),
),

Using Your Own API Service

In case you wish to use your own implementation, you can easily override the API data source.

final ChatController chatController =
    ChatController(datasource: SendMessageImplementation()); //Override
...widet body



///Create you own implementation
class SendMessageImplementation extends ChatBotDatasource {
  @override
  Future<MessageChat> sendMessage({required String message}) async {
    await Future.delayed(const Duration(milliseconds: 2000));
    //Implement your custom logic here.
    return MessageChat(
      content: message,
      created: '3:30 PM',
      role: "user",
    );
  }
