attribution_linker 1.0.0

A Flutter package for creating device fingerprints and linking attribution data using WebView. Collect comprehensive device information for analytics and attribution tracking.

Flutter Attribution Linker

A Flutter package for creating device fingerprints and attribution linking using WebView. This package collects device and browser information to create a unique fingerprint for attribution tracking.

Features

• 🔍 Device Fingerprinting: Collects comprehensive device and browser information
• 🚀 Headless WebView: Uses Flutter InAppWebView for data collection
• 💾 Caching: Fingerprint data is cached after first collection
• 🔒 Privacy-Aware: Collects only standard browser API data
• 📱 Cross-Platform: Works on iOS and Android

Installation

Add this to your package's pubspec.yaml file:

dependencies:
  attribution_linker: ^0.0.1

Usage

Basic Usage

import 'package:attribution_linker/attribution_linker.dart';

// Initialize the attribution linker
final linker = AttributionLinker();
linker.init();

// Collect fingerprint data
Map<String, dynamic> fingerprint = await linker.fingerprint;

print('Device OS: ${fingerprint['os_type']}');
print('Browser: ${fingerprint['browser_name']}');
print('Screen Resolution: ${fingerprint['screen_res']}');

Fingerprint Data Structure

The fingerprint contains the following information:

• os_type: Operating system type (android, ios, macos, windows, linux, others)
• os_name: Operating system name
• os_version: Operating system version
• browser_name: Browser name
• browser_version: Browser version
• device_model: Device model
• device_type: Device type
• device_arch: Device architecture
• device_bitness: Device bitness (32/64 bit)
• screen_res: Screen resolution (e.g., "1920x1080")
• pixel_ratio: Device pixel ratio
• timezone: System timezone
• language: Browser language
• cpu_cores: Number of CPU cores
• device_memory: Device memory in GB
• system_brightness: System theme (light/dark)
• user_agent: Full user agent string
• And more...

Technical Implementation

This package uses:

• flutter_inappwebview: For creating a headless WebView
• UAParser.js: For parsing user agent information
• Navigator APIs: For collecting device information
• Singleton Pattern: For efficient memory usage

Privacy Considerations

This package only collects information that is freely available through standard web APIs. No personal information or unique identifiers are collected without explicit user consent.
