Native Device Kit #

Enterprise-Grade Hardware & System Bridge for Flutter

Native Device Kit is a high-performance Flutter plugin that provides deep native access to device hardware, system resources, and connectivity layers on Android and iOS. It is designed as a single unified hardware bridge, enabling advanced diagnostics, sensor streaming, security checks, and peripheral communication through a clean Dart API.

Built for enterprise, fintech, healthcare, IoT, diagnostics, kiosk, and industrial-grade applications.

Overview #

Flutter abstracts away many low-level hardware and system capabilities. Native Device Kit removes this limitation by exposing rich native APIs using Kotlin and Swift, delivered through a consistent and strongly-typed Dart interface.

This plugin enables:

• Professional-grade camera diagnostics
• Advanced connectivity scanning
• Real-time system resource monitoring
• Motion sensor streaming
• Hardware security and integrity checks

All inside a single unified SDK.

Key Capabilities #

1. Advanced Camera & Optics Diagnostics #

This module provides deep introspection into device camera hardware, going far beyond standard Flutter camera plugins.

• Physical Lens Discovery Detects every available physical sensor:

  • Front
  • Rear
  • Ultra-wide
  • Telephoto

• Optical Specifications Retrieves:

  • Aperture (f-stop)
  • ISO sensitivity range (min / max)
  • Maximum supported digital zoom

• Resolution Mapping Discovers all native JPEG output resolutions supported by each sensor (for example: 4000×3000, 1920×1080, etc.)

• Auto-Focus Capability Detection Identifies whether each lens supports:

  • Hardware autofocus
  • Fixed-focus optics

• System Flashlight Control Native torch toggle with cross-platform parity

2. Intelligent Connectivity #

Provides deep system-level connectivity access and diagnostics.

• Bluetooth Low Energy (BLE)

  • Aggressive scanning mode
  • Raw advertisement packet decoding
  • Detection of device names that standard plugins often miss

• NFC

  • NDEF tag reading
  • Physical serial number extraction
  • Real-time tag detection

• USB Monitoring

  • Real-time USB hotplug event tracking
  • Device connect / disconnect notifications

3. Security & Integrity Checks #

Designed for security-sensitive applications.

• Root detection (Android)
• Jailbreak detection (iOS)
• Emulator detection (Goldfish, Ranchu, QEMU, etc.)
• Virtualized hardware detection

4. Deep System Resource Monitoring #

High-precision reporting for device health, diagnostics, and monitoring dashboards.

• Storage Metrics

  • Total disk
  • Used disk
  • Free disk (all reported in bytes for precision)

• Memory Reporting

  • Physical RAM capacity

• Battery Module

  • Precise battery percentage
  • Charging / discharging state

• Connectivity State

  • WiFi
  • Cellular
  • Offline detection

5. Motion & Hardware Sensors #

• Accelerometer Streaming

  • High-frequency real-time X, Y, Z axis updates
  • Hardware-register-level sampling for motion-aware applications

Ideal for:

• Fitness tracking
• Motion analysis
• IoT controllers
• Industrial automation

Architecture #

Flutter Application
        ↓
NativeDeviceKit (Unified Dart API)
        ↓
Platform Channels
        ↓
Android (Kotlin) → Camera2, Bluetooth, NFC, USB, Sensors, System APIs
iOS (Swift)      → AVFoundation, CoreBluetooth, CoreNFC, Sensors, System APIs

This layered design ensures:

• Native-level performance
• Minimal Flutter overhead
• Platform-specific optimizations
• Scalable feature expansion

Installation #

Add dependency in pubspec.yaml:

dependencies:
  native_device_kit: ^0.0.1

Then run:

flutter pub get

Basic Usage #

import 'package:native_device_kit/native_device_kit.dart';

final kit = NativeDeviceKit.instance;

Example Usage #

Camera Hardware Diagnostics #

final cameras = await kit.camera.getLensDiagnostics();

for (final lens in cameras) {
  print("Lens: ${lens['id']}");
  print("Aperture: ${lens['aperture']}");
  print("ISO Range: ${lens['minISO']} - ${lens['maxISO']}");
  print("Max Zoom: ${lens['maxZoom']}");
}

Bluetooth Aggressive Scan #

await kit.bluetooth.scan();

kit.bluetooth.eventStream.listen((event) {
  print("BLE Device Found: $event");
});

NFC Tag Reading #

kit.nfc.eventStream.listen((event) {
  print("NFC Tag: $event");
});

await kit.nfc.readTag();

System Resource Monitoring #

final storage = await kit.system.getStorageInfo();
final ram = await kit.system.getMemoryInfo();
final battery = await kit.system.getBatteryInfo();

print("Disk: ${storage['availableBytes']} bytes free");
print("RAM: ${ram['totalMemory']} bytes");
print("Battery: ${battery['level']}%");

Security Checks #

bool rooted = await kit.security.isRooted();
bool emulator = await kit.security.isEmulator();

print("Rooted: $rooted");
print("Emulator: $emulator");

Motion Sensor Streaming #

kit.sensors.accelerometerStream.listen((event) {
  print("X: ${event['x']}, Y: ${event['y']}, Z: ${event['z']}");
});

Example Application #

A fully functional diagnostic dashboard is included, featuring:

• Collapsible hardware inspection tiles
• Real-time sensor graphs
• Live connectivity monitors
• System resource dashboards

Designed to provide a professional diagnostic storefront experience.
