30-Second Demo

https://github.com/user-attachments/assets/d4617c73-043f-424c-9a9a-1a61d4c2d3c6

One prompt. 28 AI-driven actions. Zero test code. The AI explores a TikTok clone, navigates tabs, scrolls feeds, tests search, fills forms — all autonomously.

---

Why This Exists

Writing E2E tests is painful. Maintaining them is worse. flutter-skill takes a different approach:

• 🔌 Connects any AI agent (Claude, Cursor, Windsurf, Copilot, OpenClaw) directly to your running app via MCP
• 👀 The agent sees your screen — taps buttons, types text, scrolls, navigates — like a human tester who never sleeps
• ✅ Zero test code — no Page Objects, no XPath, no brittle selectors. Just plain English
• ⚡ Zero config — 2 lines of code, works on all 10 platforms

You: "Test the checkout flow with an empty cart, then add 3 items and complete purchase"

Your AI agent handles the rest — screenshots, taps, text entry, assertions, navigation.
No Page Objects. No XPath. No brittle selectors. Just plain English.

---

Quick Start

1. Install (30 seconds)

npm install -g flutter-skill

2. Add to your AI (copy-paste into MCP config)

{
  "mcpServers": {
    "flutter-skill": {
      "command": "flutter-skill",
      "args": ["server"]
    }
  }
}

Works with Claude Desktop, Cursor, Windsurf, Copilot, Cline, OpenClaw — any MCP-compatible agent.

3. Add to your app (2 lines for Flutter)

import 'package:flutter_skill/flutter_skill.dart';

void main() {
  if (kDebugMode) FlutterSkillBinding.ensureInitialized();
  runApp(MyApp());
}

4. Test — just talk to your AI:

"Launch my app, explore every screen, and report any bugs"

That's it. Zero configuration. Zero test code. Works in under 60 seconds.

10 Platforms, One Tool

Most testing tools work on 1-2 platforms. flutter-skill works on 10.

Platform	SDK	Test Score
Flutter (iOS/Android/Web)	flutter_skill	✅ 188/195
React Native	sdks/react-native	✅ 75/75
Electron	sdks/electron	✅ 75/75
Tauri (Rust)	sdks/tauri	✅ 75/75
Android (Kotlin)	sdks/android	✅ 74/75
KMP Desktop	sdks/kmp	✅ 75/75
.NET MAUI	sdks/dotnet-maui	✅ 75/75
iOS (Swift/UIKit)	sdks/ios	✅ 19/19
Web (any website)	sdks/web	✅
Web CDP (zero-config)	No SDK needed	✅ 141/156

Total: 656/664 tests passing (98.8%) — each platform tested against a complex social media app with 50+ elements.

⚡ Performance

Real benchmarks from automated test runs against a complex social media app:

Operation	Web (CDP)	Electron	Android
connect	93 ms	55 ms	103 ms
tap	1 ms	1 ms	2 ms
enter_text	1 ms	1 ms	2 ms
inspect	3 ms	12 ms	10 ms
snapshot	2 ms	8 ms	29 ms
screenshot	31 ms	80 ms	88 ms
eval	1 ms	—	—

Token efficiency: snapshot() returns a structured element tree instead of an image — 87–99% fewer tokens than sending screenshots to your AI agent.

How fast is that? A tap takes 1–2 ms end-to-end. Browser automation tools like Playwright and Selenium typically take 50–100 ms for the same operation. That's 50–100× faster, because flutter-skill talks directly to the app runtime instead of going through WebDriver or CDP indirection.

Heavy DOM Sites (Real-World)

Tested 15 MCP tools against production websites — 75/75 passed, zero timeouts:

Site	Tools	Total Time	snapshot	screenshot	count_elements
YouTube	15/15 ✅	6.9s	43 ms	30 ms	4 ms
Amazon	15/15 ✅	14.2s	1 ms	5 ms	2 ms
Reddit	15/15 ✅	17.9s	6 ms	32 ms	51 ms
Hacker News	15/15 ✅	4.8s	53 ms	188 ms	1 ms
Wikipedia	15/15 ✅	7.8s	15 ms	336 ms	1 ms

Total time includes page load. Tool execution is consistently sub-100ms even on heavy DOM sites.

🧠 AI-Native: 95% Fewer Tokens

Most AI testing tools send screenshots to the LLM — each one costs ~4,000 tokens.

flutter-skill uses Chrome's Accessibility Tree to give your AI a compact semantic summary of any page:

// page_summary → ~200 tokens (vs ~4,000 for a screenshot)
{
  "title": "Shopping Cart",
  "nav": ["Home", "Products", "Cart", "Account"],
  "forms": [{"input:Coupon Code": "text"}],
  "buttons": ["Apply", "Checkout", "Continue Shopping"],
  "features": {"search": true, "pagination": true},
  "links": 47, "inputs": 3
}

Then batch multiple actions in one call:

// explore_actions → 5 actions per call (vs 5 separate tool calls)
{"actions": [
  {"type": "fill", "target": "input:Coupon Code", "value": "SAVE20"},
  {"type": "tap", "target": "button:Apply"},
  {"type": "tap", "target": "button:Checkout"},
  {"type": "fill", "target": "input:Email", "value": "test@example.com"},
  {"type": "tap", "target": "button:Continue"}
]}

Result: Your AI agent tests faster, costs less, and understands pages better than screenshot-based tools.

	flutter-skill	Screenshot-based tools
Tokens per page	~200	~4,000
Actions per call	5+	1
Understands semantics	✅ roles, names, state	❌ pixels only
Works with Shadow DOM	✅	❌

"Test login with wrong password"	Screenshots → enters creds → taps login → verifies error
"Explore every screen and report bugs"	Systematically navigates all screens, tests all elements
"Fill registration with edge cases"	Tests emoji 🌍, long strings, empty fields, special chars
"Compare checkout flow on iOS and Android"	Runs same test on both platforms, compares screenshots
"Take screenshots of all 5 tabs"	Taps each tab, captures state
