flutter_ai_assistant #

A drop-in AI assistant for Flutter apps. Understands your UI through the Semantics tree, executes multi-step tasks autonomously, and works with any LLM provider — Gemini, Claude, or OpenAI.

One widget. Full app control. Zero hardcoding.

AiAssistant(
  config: AiAssistantConfig(
    provider: GeminiProvider(apiKey: 'your-key'),
  ),
  child: MaterialApp(home: HomeScreen()),
)

Your users can now say "order 2 onions from the store" and the assistant will navigate to the store, search for onions, add them to cart, adjust the quantity, and proceed to checkout — all autonomously.

How It Works #

User speaks or types a command
        |
        v
+-------------------+
|  Semantics Walker  |  Reads the live UI tree — every button,
|  (Screen Context)  |  label, text field, and scrollable area
+-------------------+
        |
        v
+-------------------+
|    ReAct Agent     |  Reason -> Act -> Observe loop
|   (LLM + Tools)   |  Plans steps, calls tools, checks results
+-------------------+
        |
        v
+-------------------+
|  Action Executor   |  Taps buttons, fills text fields, scrolls,
|  (UI Automation)   |  navigates routes — like a real user
+-------------------+
        |
        v
    Task complete — user sees the result

The assistant doesn't use hardcoded screen coordinates or widget keys. It reads Flutter's Semantics tree — the same accessibility layer used by screen readers — to understand what's on screen and interact with it. This means it works with any Flutter app out of the box, regardless of your widget structure.

Features #

Core Intelligence #

ReAct Agent Loop — Reason, Act, Observe cycle with automatic verification
Multi-provider LLM — Gemini, Claude, and OpenAI out of the box; bring your own via LlmProvider interface
Built-in Tools — tap, type, scroll, navigate, go back, long press, increase/decrease values, ask user, hand off to user, read screen (10 always-on + hand_off_to_user when confirmDestructiveActions is true)
Custom Tools — register your own business-logic tools (check inventory, call APIs, etc.)
Conversation Memory — multi-turn context with automatic management
Circuit Breaker — escalates after consecutive failures instead of looping forever

UI Understanding #

Semantics Tree Walking — reads every interactive element, label, and state on screen
Progressive Screen Knowledge — remembers previously visited screens for smarter planning
Screenshot Support — optional visual context for chart/image understanding (multimodal)
Context Caching — avoids redundant tree walks with configurable TTL
App Manifest — optional code-generated "building map" of your entire app for instant navigation

Voice #

Speech-to-Text — multi-locale recognition with automatic locale selection
Text-to-Speech — auto-detects Hindi/English and switches voice accordingly
Confidence Filtering — discards low-confidence noise before it reaches the LLM
Summary Mode — speaks only the first sentence of long responses; full text stays in chat

UI #

Floating Action Button — draggable, edge-snapping, with processing indicator and unread badge
Chat Overlay — full-screen chat with animated action feed showing live progress
Rich Messages — text, images, interactive buttons, and cards in chat bubbles
Handoff Mode — for irreversible actions, the overlay clears so the user can tap the final button themselves
Response Popup — compact result card above the FAB after auto-close
Suggestion Chips — configurable quick-start actions in empty state
Post-task Chips — contextual follow-up buttons after task completion
Auto-close — overlay closes after task completion; action results auto-dismiss, info results persist

Safety #

Destructive Action Handoff — purchases, deletions, and payments are handed to the user for the final tap
ask_user Guards — code-level enforcement prevents the LLM from asking unnecessary confirmation questions
Verification Passes — after the agent says "done", the system re-checks the screen to catch premature completion
Max Iterations — hard cap on agent loop steps to prevent runaway execution
Processing Timeout — 3-minute safety timeout on active processing

Quick Start #

1. Add the dependency #

dependencies:
  flutter_ai_assistant: ^0.1.0

2. Wrap your app and wire the navigator observer #

The assistant needs two things: the AiAssistant widget wrapping your app, and its AiNavigatorObserver added to your MaterialApp so it can track route changes.

import 'package:flutter_ai_assistant/flutter_ai_assistant.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return AiAssistant(
      config: AiAssistantConfig(
        provider: GeminiProvider(apiKey: 'YOUR_GEMINI_API_KEY'),
      ),
      child: Builder(
        builder: (context) {
          // Access the controller to get the navigator observer.
          final aiCtrl = AiAssistant.read(context);
          return MaterialApp(
            navigatorObservers: [aiCtrl.navigatorObserver],
            home: HomeScreen(),
          );
        },
      ),
    );
  }
}

That's it. A floating AI button appears. Users can tap it, type or speak a command, and the assistant executes it.

Why the Builder? AiAssistant.read(context) requires the AiAssistant to be an ancestor in the widget tree. The Builder creates a new context below AiAssistant so the controller is accessible. Without the navigator observer, the assistant won't know which screen the user is on.

3. Add routes and descriptions (recommended) #

Telling the assistant about your app's screens makes it dramatically smarter:

AiAssistant(
  config: AiAssistantConfig(
    provider: GeminiProvider(apiKey: apiKey),
    knownRoutes: ['/home', '/store', '/cart', '/profile', '/settings'],
    routeDescriptions: {
      '/home': 'Main dashboard with quick actions',
      '/store': 'Browse and buy products',
      '/cart': 'Shopping cart with checkout',
      '/profile': 'User profile and account settings',
      '/settings': 'App preferences and configuration',
    },
  ),
  child: MaterialApp(...),
)

4. Add domain knowledge (recommended) #

Teach the assistant your app's vocabulary and workflows:

AiAssistant(
  config: AiAssistantConfig(
    provider: GeminiProvider(apiKey: apiKey),

    // What your app does (for the LLM's understanding)
    appPurpose:
      'ShopApp is a grocery delivery app. Users browse products, '
      'add to cart, and checkout. "order"/"buy" = full purchase flow. '
      '"cart" = shopping cart. "balance" = wallet screen.',

    // Behavioral rules specific to your app
    domainInstructions:
      'QUANTITIES: Tap ADD first (sets qty=1), then tap "+" to increase. '
      '"5 onions" means ADD then "+" 4 times.\n\n'
      '"order X" means COMPLETE the full purchase: add to cart, '
      'go to cart, checkout, and hand off payment.',

    // Example flows the LLM should learn from
    fewShotExamples: [
      'User: "order 2 onions"\n'
      'Actions: navigate_to_route("/store") -> set_text("Search", "onion") -> '
      'tap_element("ADD", parentContext: "Onion") -> increase_value("+") -> '
      'navigate_to_route("/cart") -> tap_element("Checkout")\n'
      'Response: "2 onions added and ready for checkout!"',
    ],
  ),
  child: MaterialApp(...),
)

LLM Providers #

The package includes three providers. All share the same LlmProvider interface, so switching is a one-line change.

Gemini (Google) #

GeminiProvider(
  apiKey: 'your-gemini-api-key',
  model: 'gemini-2.0-flash',     // default
  temperature: 0.2,               // default
  requestTimeout: Duration(seconds: 45),
)

Uses the google_generative_ai package. Supports function calling and multimodal (images).

Claude (Anthropic) #

ClaudeProvider(
  apiKey: 'sk-ant-...',
  model: 'claude-sonnet-4-20250514',  // default
  maxTokens: 4096,
  temperature: 0.2,
  baseUrl: 'https://api.anthropic.com/v1',  // override for proxies
)

Uses the Anthropic Messages API via HTTP. No additional SDK dependency.

OpenAI (GPT-4) #

OpenAiProvider(
  apiKey: 'sk-...',
  model: 'gpt-4o',               // default
  temperature: 0.2,
  baseUrl: 'https://api.openai.com/v1',  // override for Azure
)

Uses the Chat Completions API via HTTP. Override baseUrl for Azure OpenAI or proxies.

Bring Your Own Provider #

Implement the LlmProvider interface:

abstract class LlmProvider {
  Future<LlmResponse> sendMessage({
    required List<LlmMessage> messages,
    required List<ToolDefinition> tools,
    String? systemPrompt,
  });

  void dispose() {}
}

The package handles conversation format, tool schemas, and response parsing — your provider just needs to translate between LlmMessage/LlmResponse and your API's format.

Built-in error handling: All HTTP providers share typed exceptions (RateLimitException, ContextOverflowException, AuthenticationException, ContentFilteredException) and automatic retry with exponential backoff on rate limits.

Custom Tools #

AiAssistantConfig(
  provider: GeminiProvider(apiKey: apiKey),
  customTools: [
    AiTool(
      name: 'check_inventory',
      description: 'Check if a product is in stock and get its current price.',
      parameters: {
        'productName': const ToolParameter(
          type: 'string',
          description: 'The name of the product to check.',
        ),
      },
      required: ['productName'],
      handler: (args) async {
        final name = args['productName'] as String;
        final result = await inventoryService.check(name);
        return {
          'inStock': result.inStock,
          'price': result.price,
          'quantity': result.available,
        };
      },
    ),
  ],
)

The LLM sees your tool's name, description, and parameters alongside the built-in tools. When it decides your tool is relevant, it calls it — the return map is fed back as the tool result.

Built-in Tools #

These are registered automatically and work on any Flutter app:

Tool	What it does
`tap_element`	Taps a button, link, or interactive element by its label. Supports `parentContext` for disambiguation.
`set_text`	Enters text into any text field — auto-finds hidden/unfocused fields, activates search bars.
`scroll`	Scrolls up, down, left, or right to find off-screen content.
`navigate_to_route`	Navigates to a named route (e.g. `/store`, `/cart`).
`go_back`	Pops the current route (back button).
`get_screen_content`	Re-reads the current screen's semantics tree for fresh context.
`long_press_element`	Long presses an element (for context menus, etc.).
`increase_value`	Increases a quantity stepper or slider value.
`decrease_value`	Decreases a quantity stepper or slider value.
`ask_user`	Asks the user a question and waits for their response. Used only when genuinely ambiguous.
`hand_off_to_user`	Clears the overlay so the user can tap the final irreversible action button themselves. Only available when `confirmDestructiveActions: true` (default).

App Manifest (Code Generation) #

For large apps, you can generate a rich "building map" that gives the assistant detailed knowledge of every screen without having to visit them first:

dart run flutter_ai_assistant:generate \
  --routes-file=lib/models/routes.dart \
  --router-file=lib/app/router.dart \
  --api-key=YOUR_GEMINI_KEY \
  --output=lib/ai_app_manifest.g.dart

Or with an env file:

dart run flutter_ai_assistant:generate --env=.env.staging

This scans your route definitions and widget source code, sends each screen to Gemini for analysis, and generates a Dart file containing an AiAppManifest with:

Screen descriptions — what each screen does, its sections, and interactive elements
Navigation links — how screens connect to each other
Multi-step flows — common user journeys spanning multiple screens
Global navigation — bottom nav tabs, side menu structure

Pass the generated manifest to the config:

import 'ai_app_manifest.g.dart';

AiAssistantConfig(
  provider: GeminiProvider(apiKey: apiKey),
  appManifest: aiAppManifest,
)

The manifest provides a two-tier context system:

Tier 1 (always loaded): App overview, all screens, navigation structure, flows
Tier 2 (on-demand): Detailed screen sections, elements, and actions for the current screen

Voice I/O #

Speech-to-Text (Input) #

The assistant uses speech_to_text with intelligent locale resolution:

AiAssistantConfig(
  voiceEnabled: true,
  preferredLocales: ['en_US', 'hi_IN', 'es_ES'],  // your priority order
)

On first listen, queries the device for available locales
Picks the best match from your preferred list (supports exact match, hyphen variants, and language prefix matching)
Partial transcription shown live as the user speaks
Low-confidence results are filtered before reaching the LLM

Text-to-Speech (Output) #

The assistant uses flutter_tts with automatic language detection:

AiAssistantConfig(
  enableTts: true,
)

Auto-detects language: Devanagari script or Hindi/Hinglish particles -> Hindi voice; otherwise English
Summary mode: Long responses are truncated to the first sentence for TTS; full text stays in chat
Progress updates: During multi-step tasks, the assistant speaks status updates ("Opening the store...", "Searching for onions...")

Analytics Events #

Every significant action in the assistant lifecycle emits a structured AiEvent:

AiAssistantConfig(
  onEvent: (event) {
    analytics.logEvent(
      name: 'ai_${event.type.name}',
      parameters: event.properties.map(
        (k, v) => MapEntry(k, v?.toString() ?? ''),
      ),
    );
  },
)

Event Categories #

Conversation lifecycle: conversationStarted, conversationCompleted, conversationError, messageSent, messageReceived, conversationCleared

Agent loop: agentIterationStarted, agentIterationCompleted, agentCancelled, agentTimeout, agentMaxIterationsReached, agentOrientationCheckpoint, agentCircuitBreakerFired

LLM communication: llmRequestSent, llmResponseReceived, llmError, llmEmptyResponse

Tool execution: toolExecutionStarted, toolExecutionCompleted, screenContentCaptured, screenStabilizationAttempted

Voice: voiceInputStarted, voiceInputCompleted, voiceInputError, ttsStarted

UI interactions: chatOverlayOpened, chatOverlayClosed, suggestionChipTapped, buttonTapped, handoffStarted, handoffCompleted, askUserStarted, askUserCompleted, stopRequested, responsePopupShown

Navigation: routeChanged, navigationExecuted

Each event includes relevant properties (documented on the AiEventType enum). For example, toolExecutionCompleted includes toolName, arguments, success, error, durationMs, and iteration.

Rich Chat Content #

Chat messages support rich content blocks beyond plain text:

Interactive Buttons #

// Post-task follow-up chips
AiAssistantConfig(
  postTaskChipsBuilder: (response) {
    final addedToCart = response.actions.any((a) =>
      a.toolName == 'tap_element' &&
      (a.arguments['label'] as String?)?.contains('ADD') == true);

    if (addedToCart) {
      return ButtonsContent(
        buttons: [
          ChatButton(label: 'View my cart', icon: Icons.shopping_cart),
          ChatButton(label: 'Continue shopping', icon: Icons.store),
        ],
      );
    }
    return null;
  },
)

Suggestion Chips #

AiAssistantConfig(
  initialSuggestions: [
    AiSuggestionChip(
      icon: Icons.directions_car,
      label: 'Book a ride',
      message: 'Book me a ride',
    ),
    AiSuggestionChip(
      icon: Icons.storefront,
      label: 'Browse store',
      message: 'Take me to the store',
    ),
    AiSuggestionChip(
      icon: Icons.account_balance_wallet,
      label: 'Check balance',
      message: 'Show my wallet balance',
    ),
  ],
)

Content Types #

Type	Description
`TextContent`	Plain text block
`ImageContent`	Inline image (URL or bytes) with optional caption
`ButtonsContent`	Group of tappable quick-reply buttons (wrap or column layout)
`CardContent`	Rich card with title, subtitle, image, and action buttons

Button styles: primary (filled), outlined (default), destructive (red), success (green).

Data Flow #

User input (text or voice) -> AiAssistantController
Context capture -> SemanticsWalker reads the UI tree, ContextCache manages freshness
Agent loop -> ReactAgent sends context + history + tools to the LlmProvider
Tool execution -> LLM returns tool calls, ActionExecutor performs them on the live UI
Observation -> Screen is re-read, results fed back to the LLM
Repeat until the LLM returns a text response (task complete)
Verification -> System re-checks the screen to confirm task completion
Response -> Shown in chat, spoken via TTS if voice-initiated

API Reference #

Accessing the Controller #

From anywhere in the widget tree below AiAssistant:

// With rebuild on changes (in build methods)
final ctrl = AiAssistant.of(context);
