Before You Start

You have to create .env file into base of your project and give your OpenAI API Key as BEARER = 'API_KEY'

OR

Go to file lib/config/constants/api_constants.dart then

Change this

import 'package:flutter_dotenv/flutter_dotenv.dart' show dotenv; // Remove this line

class APIConstants {
     //..
     static String authToken = 'Bearer ${dotenv.env['BEARER_TOKEN']}'
     //..
}

to this

class APIConstants {
     //..
     static String authToken = 'Bearer API_KEY'
     //..
}

Hive

I used hive for save chat history. I firstly tried save history of messages as List<Message?> but because of limitation of Dart it was not possible to save generic list to Hive so i created a Class named HiveChatModel and saved it as is.

class HiveChatModel{
  String? title;
  DateTime? date;
  List<Message?>? chat;
}

Ability to load history messages and continue to chat then saved it again i used Hive.put()

Hive.put(sesionName,messages)

when you load a chat, you also get sessionName

sessionName is generated as session_${lengthOfHiveHistoryList}
