Flutter SDK Конструктор чат-ботов

Flutter has become the leading cross-platform framework, enabling developers to build natively compiled applications for iOS, Android, Web, macOS, Windows, and Linux from a single Dart codebase. Its adoption has exploded — Google reports over 1 million published Flutter apps, and companies like BMW, Alibaba, ByteDance, and eBay use it in production.

When you build with Flutter, you expect your tools to work everywhere Flutter does. The Conferbot Flutter SDK delivers exactly that — a cross-platform chatbot widget that renders beautifully on every platform Flutter supports. Material Design 3 components ensure your chatbot looks native on Android, while adaptive design adjusts gracefully for iOS, Web, and Desktop.

The SDK is built with Dart null-safety, integrates with Flutter's widget tree naturally, and follows the same widget composition patterns Flutter developers already know. You get the full power of Conferbot's no-code chatbot builder, AI capabilities, and live chat — all rendered through native Flutter widgets instead of a WebView.

This guide covers everything you need to integrate a production-ready chatbot into your Flutter application in 2026: installation, key features, theming, event handling, and best practices for cross-platform deployment.

The Conferbot Flutter SDK is distributed as a standard Dart package via pub.dev, following Flutter's standard dependency management workflow.

Step 1: Add the Dependency

Add the package to your pubspec.yaml:

dependencies:
  conferbot_flutter: ^1.0.0

Step 2: Install

Run the install command:

flutter pub get

Step 3: Initialize the SDK

Import the package and initialize Conferbot in your app's main entry point:

import 'package:conferbot_flutter/conferbot_flutter.dart';

Wrap your MaterialApp with the ConferbotProvider widget, passing your bot ID:

ConferbotProvider(botId: 'YOUR_BOT_ID', child: MaterialApp(...))

Step 4: Add the Chat Widget

Place the ConferbotChat widget in your widget tree:

• Floating Action Button — ConferbotFloatingButton() adds a chat bubble that opens the full chat overlay
• Full Screen — ConferbotChatScreen() renders the chat as a full-screen page, suitable for Navigator push
• Embedded — ConferbotChatWidget() renders inline within your layout for custom placement

Step 5: Configure Push Notifications (Optional)

For push notification support:

• Set up Firebase Cloud Messaging using firebase_messaging package
• Pass the FCM token to the SDK: Conferbot.instance.setDeviceToken(token)
• For iOS, configure APNs certificates in your Apple Developer account

Basic integration takes approximately 10 minutes. The SDK supports Flutter 3.0+ and Dart 3.0+ with full null-safety.

The Conferbot Flutter SDK is designed to be a first-class Flutter citizen, following the framework's principles of composition, performance, and platform adaptivity.

Material Design 3 Components

The SDK ships with Material Design 3 (Material You) widgets that automatically adapt to your app's color scheme and typography. Message bubbles, input fields, buttons, and headers all follow Material 3 guidelines, ensuring visual consistency with the rest of your Android app. On iOS, the widgets gracefully adapt with platform-appropriate styling.

Cross-Platform Support

The same Flutter code works on all supported platforms:

• iOS — Adaptive styling with Cupertino touches
• Android — Full Material Design 3 with dynamic theming
• Web — Responsive layout that adjusts to browser viewport
• macOS, Windows, Linux — Desktop-optimized layout with keyboard navigation

Dart Null-Safety

The entire SDK is written with sound null-safety, ensuring compile-time safety guarantees. No runtime null reference errors from the SDK — ever. This aligns with Flutter's push toward null-safe Dart code across the ecosystem.

Smooth Animations

Message entry, typing indicators, widget transitions, and button interactions are all animated at 60fps using Flutter's animation framework. The chat experience feels fluid and responsive, matching the quality standard users expect from native Flutter apps.

Push Notifications

Receive notifications when the bot responds while the app is in the background. Works with Firebase Cloud Messaging for both iOS and Android. Notifications are customizable with your own titles, body text, and sound.

State Management Integration

The SDK works alongside any state management solution — Provider, Riverpod, Bloc, GetX, or MobX. Access chat state through Conferbot's own ChangeNotifier or integrate with your existing state architecture using provided streams and callbacks.

Offline Support

Messages are cached locally when the device is offline and synced automatically when connectivity returns. The SDK uses Dart's connectivity detection to manage queue state transparently.

The SDK integrates with Flutter's theming system, letting you customize the chat UI to match your app perfectly.

ConferbotTheme

Pass a ConferbotTheme to the provider to customize visual appearance:

• primaryColor — Main accent color for send button, links, and active elements
• backgroundColor — Chat screen and message area background
• userBubbleColor / botBubbleColor — Separate colors for user and bot message bubbles
• textStyle — Custom TextStyle for message text, headers, and placeholders
• borderRadius — Control the roundness of bubbles and input fields
• botAvatar — Custom image for the bot avatar (AssetImage or NetworkImage)
• inputDecoration — Full InputDecoration customization for the text input field

Dark Mode

The SDK automatically respects MediaQuery.platformBrightness. Provide separate light and dark themes, and the chat UI switches automatically when the device or app toggles dark mode.

Custom Widget Builders

Replace default widgets with your own using builder callbacks:

• messageBubbleBuilder — Custom widget for message bubbles
• inputBarBuilder — Custom widget for the text input area
• quickReplyBuilder — Custom widget for quick reply buttons
• headerBuilder — Custom widget for the chat header
• loadingBuilder — Custom widget for loading states

Event Callbacks

React to chatbot events for custom business logic:

• onMessageReceived — Bot message delivered to the user
• onConversationCompleted — A conversation flow reaches its end
• onAgentHandoff — Conversation transferred to a live agent
• onDataCaptured — User provides contact or form data through the bot
• onError — SDK encounters an error (network, auth, etc.)

Flutter apps span every industry. Here are the most effective chatbot integrations for common Flutter app categories.

E-Commerce Apps

Product discovery assistance, size and compatibility guides, order tracking, return processing, and personalized recommendations. Flutter e-commerce apps with in-app chatbots see 20-30% higher customer satisfaction scores compared to apps that redirect users to external support channels. Explore e-commerce chatbot solutions.

FinTech and Banking

Account balance inquiries, transaction explanations, fraud alert handling, loan application assistance, and financial product recommendations. In-app chatbots in financial apps must handle sensitive data securely — the SDK transmits all data over HTTPS and stores nothing locally beyond the current session.

Healthcare and Telemedicine

Appointment booking, symptom pre-screening, medication reminders, lab result explanations, and provider search. Healthcare apps using chatbots reduce call center volume by 30-50% while improving patient access to information.

Education and EdTech

Course navigation, assignment help, schedule inquiries, enrollment support, and interactive quizzes. Education apps find that conversational interfaces increase student engagement by 25-35% compared to traditional help menus.

On-Demand Services

Ride-hailing, food delivery, home services — these apps handle high volumes of status inquiries, complaints, and booking modifications. A chatbot resolves the simple cases instantly while routing complex issues to live agents.

SaaS and Productivity

Feature guidance, troubleshooting, upgrade prompts, and feedback collection. SaaS apps with embedded chatbots reduce support ticket volume by 40% and increase feature discovery through guided conversations.
