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

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.
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.
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 |
| 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.

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.
