Eilya Chat - Flutter SDK

Official Flutter/Dart SDK for Eilya Chat -- embed an AI-powered chat widget in your Flutter app.

Installation

Add to your pubspec.yaml:

dependencies:
  eilya_chat: ^1.0.0

Then run:

flutter pub get

Quick Start

import 'package:eilya_chat/eilya_chat.dart';

// Initialize with your API key
final chat = EilyaChat.initialize(
  apiKey: 'eck_live_your_api_key_here',
);

// Open the chat widget (creates session automatically)
final session = await chat.open(context);
print('Session started: ${session.sessionId}');

// Send a message
try {
  final reply = await chat.sendMessage(content: 'Hello!');
  print('Assistant: ${reply.content}');
} on SessionExpiredException {
  print('Session expired. Create a new one.');
} on RateLimitedException catch (e) {
  print('Rate limited. Retry after ${e.retryAfterSeconds}s');
}

Sandbox Mode

Use a test API key (prefix eck_test_) for development. In sandbox mode:

• Messages are processed but not billed
• Responses may use mock data

final chat = EilyaChat.initialize(
  apiKey: 'eck_test_your_test_key_here',
);

Configuration

final chat = EilyaChat.initialize(
  apiKey: 'eck_live_...',
  config: EilyaChatConfig(
    brandColor: '#6366F1',
    position: WidgetPosition.bottomRight,
    language: 'en',
    systemPrompt: 'You are a helpful assistant.',
    welcomeMessage: 'Hello! How can I help you?',
    timeout: Duration(seconds: 30),
  ),
);

Listening for Messages

Use the onMessage stream to receive real-time assistant responses:

chat.onMessage.listen((message) {
  print('${message.role}: ${message.content}');
});
