Flutter Device Inspector 🔍 #

A high-performance, cross-platform Flutter plugin for retrieving deep hardware and software specifications. It provides a unified API to access unique device identifiers, hardware metrics (RAM, CPU, Storage), and system identity across Android, iOS, and Web.

🚀 Key Features #

• 🛡️ Constant Unique ID:
  • Mobile: Persistent hardware-based identifiers.
  • Web: Advanced Fingerprinting (SHA-256) that remains constant even after browser reinstallation.
• 💾 Memory Insights: Get total physical RAM formatted in GB.
• 📂 Storage Metrics: Retrieve total internal storage capacity in MB.
• ⚙️ Processor Details: Real-time CPU/Hardware name retrieval.
• 🆔 Device Identity: Manufacturer, Brand, and Model detection.
• 🌐 Full Web Support: Seamless integration for browser-based Flutter apps.

📦 Installation #

Add this to your pubspec.yaml:

dependencies:
  flutter_device_inspector: ^0.0.1

Then run:

flutter pub get

🛠 Usage #

1. Unified Device Info (Recommended) #

Fetch all device details in a single asynchronous call using the DeviceInfo model.

import 'package:flutter_device_inspector/flutter_device_inspector.dart';

void getDetails() async {
  DeviceInfo info = await FlutterDeviceInspector.getFullInfo();

  print('Unique ID: ${info.deviceId}');
  print('Model: ${info.model}');
  print('RAM: ${info.ram}');           // e.g., "7.45 GB"
  print('Storage: ${info.totalStorage}'); // e.g., "121845 MB"
  print('CPU: ${info.cpu}');           // e.g., "Snapdragon 865"
  print('OS: ${info.osVersion}');
}

2. Individual Property Access #

If you only need a specific piece of information:

String? deviceId = await FlutterDeviceInspector.getDeviceId();
String? ram = await FlutterDeviceInspector.getTotalRam();
String? storage = await FlutterDeviceInspector.getTotalStorage();

📱 Platform Implementation Details #

🔒 About the Web Unique ID #

The Web ID is generated using Browser Fingerprinting. It combines hardware properties (CPU cores, RAM, Screen resolution) and browser metadata to create a unique SHA-256 hash.

• Persistence: Unlike cookies or localStorage, this ID remains the same even if the user uninstalls and reinstalls the browser, as it is derived from the device's hardware signature.

🧪 Example App #

The project includes a premium example app (Material 3) located in the example/ folder. It demonstrates how to build a professional device dashboard using this plugin.
