unilitix 2.0.72

African-first mobile UX analytics for Flutter. Pure Dart SDK — track sessions, screens, events and crashes with a single line of code.

Unilitix Flutter SDK

Version: 2.0.72 · pub.dev · GitHub

Unilitix is a mobile analytics SDK built for African markets. It captures session replays, screen flows, custom events, and user identity — with offline-first data delivery and Africa-specific context (network type, carrier, power outage correlation).

Requirements

Platform	Minimum	Recommended
Flutter	3.10+	3.22+
Dart	3.0+	—
Android	API 21+	API 26+ (full session replay)
iOS	13.0+	—

Installation

flutter pub add unilitix

Or add manually to pubspec.yaml:

dependencies:
  unilitix: ^2.0.72

Then run:

flutter pub get

---

Quick Start

1. Initialize the SDK

In your main.dart, initialize Unilitix before running your app:

import 'package:unilitix/unilitix_flutter.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Unilitix.init('YOUR_API_KEY');
  Unilitix.runApp(MyApp());
}

Get your API key from Dashboard → Settings → Apps.

---

2. Set Up Your App Widget

Add Unilitix.observer to navigatorObservers and wrap your app content with UnilitixWidget inside the builder:

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      navigatorObservers: [Unilitix.observer],
      builder: (context, child) => UnilitixWidget(child: child!),
    );
  }
}

⚠️ Always use the builder pattern. Do not wrap MaterialApp itself with UnilitixWidget — this causes blank frames in session replay.

---

3. Verify Integration

Run your app in debug mode. Within 5 seconds you should see:

[Unilitix] SDK initialized ✅ v2.0.72
[Unilitix] Session started ✅ abc123…
[Unilitix] Screen → /home

If you see Observer ⚠️ not connected, ensure Unilitix.observer is in navigatorObservers. The warning clears automatically on first navigation.

---

Screen Tracking

Screen tracking is automatic when Unilitix.observer is added. No additional code needed for standard MaterialApp routing.

go_router

GoRouter(
  observers: [Unilitix.observer],
  routes: [...],
)

Named Routes

For screen names to appear correctly in the dashboard, all routes must have a name:

Navigator.push(context, MaterialPageRoute(
  settings: RouteSettings(name: '/payment'),
  builder: (context) => PaymentScreen(),
));

Without a name, routes appear as MaterialPageRoute<dynamic> in your analytics.

---

Identify Users

Associate sessions with a user ID after login. Call identify() in two places:

// 1. After successful login
await AuthService.login(email, password);
Unilitix.identify(
  user.id,
  {
    "email": user.email,
    "name": user.name,
    "phone": user.phoneNumber,
    "account_type": user.accountType,
  },
);

// 2. On app startup — if already logged in
void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Unilitix.init('YOUR_API_KEY');
  final user = await AuthService.getCurrentUser();
  if (user != null) {
    Unilitix.identify(user.id, {"name": user.name, "email": user.email});
  }
  Unilitix.runApp(MyApp());
}

⚠️ Calling identify() only on login means returning users who skip login will appear as anonymous.

---

Track Custom Events

Unilitix.track("loan_applied", {
  "amount":    50000,
  "loan_type": "personal",
  "currency":  "NGN",
});

Event names should be snake_case. Property values can be String, int, double, or bool.

---

Session Replay

Session replay is enabled by default. The SDK captures screenshots and widget tree snapshots and uploads them incrementally every 30 seconds.

Android: Uses native PixelCopy (API 26+) as the primary capture method, with automatic fallback to Dart-based capture for API 21–25. No configuration needed.

iOS: Uses UIView.drawHierarchy via the Flutter platform channel.

To disable:

await Unilitix.init(
  'YOUR_API_KEY',
  config: UnilitixConfig(
    captureScreenshots: false,
    captureSnapshots: false,
  ),
);

Session replay requires the Growth plan or above.

---

Privacy Masking

Exclude sensitive widgets from session recordings:

UnilitixPrivate(
  child: CreditCardForm(),
)

⚠️ UnilitixPrivate excludes widgets from the wireframe snapshot only. It does not mask pixel screenshots. To prevent sensitive content in screenshots, set captureScreenshots: false in UnilitixConfig.

---

Advanced Configuration

await Unilitix.init(
  'YOUR_API_KEY',
  config: UnilitixConfig(
    debug: false,                        // disable SDK logs in production
    captureSnapshots: true,              // wireframe replay
    captureScreenshots: true,            // pixel screenshot replay
    maskInputs: true,                    // mask text field input
    flushIntervalSeconds: 30,            // how often to upload data
    sessionTimeoutSeconds: 1800,         // session inactivity timeout (30 min)
    uploadScreenshotsOnWifiOnly: false,  // restrict uploads to WiFi
  ),
);

---

Session Control

// Manually start a new session
await Unilitix.startSession();

// End the current session
await Unilitix.endSession();

// Force upload all queued data immediately
await Unilitix.flush();

---

Privacy Controls

// Stop tracking (e.g. user opts out)
Unilitix.optOut();

// Resume tracking
Unilitix.optIn();

// Clear user identity and reset anonymous ID
Unilitix.reset();

---

Android Setup

No additional setup required. Ensure your android/app/build.gradle has:

compileSdk 35
minSdk 21

For NDK-dependent builds, pin the NDK version:

// android/app/build.gradle.kts
android {
  ndkVersion = "27.0.12077973"
}

---

iOS Setup

Add the following to your ios/Podfile if not already present:

platform :ios, '13.0'

Then run:

cd ios && pod install

No additional Info.plist entries are required.

---

Troubleshooting

Blank or black frames in session replay (Android)

Ensure your app meets these requirements:

• compileSdk 35 or higher
• Flutter 3.22+ for full Impeller compatibility
• SDK v2.0.66 or above

Sessions showing as incomplete

Ensure Unilitix.observer is added to navigatorObservers. Sessions require at least one navigation event to complete properly.

Observer warning at startup

[Unilitix] Observer ⚠️ not connected

This warning fires during SDK init before MaterialApp is built. It clears automatically on first navigation. If it persists, confirm Unilitix.observer is in navigatorObservers.

Anonymous ID changes after app update

If upgrading from v2.0.70 or earlier to v2.0.72, users will receive a new anonymous ID on first launch. This is a one-time break — anonymous IDs are now stable across all future app updates.

Events returning 402

Your workspace has reached its event limit. Upgrade your plan or contact support to increase your limit.
