⬇️ Download Speed: Accurate download speed measurements in Mbps
⬆️ Upload Speed: Precise upload speed measurements in Mbps
📊 Signal Strength: WiFi signal strength indicator (1-5)
🧵 Background Processing: All operations run on background threads to prevent UI freezing
🧪 Speed Tests: Run dedicated download and upload speed tests
⏱️ Streaming API: Subscribe to real-time network speed updates
🔌 Easy Integration: Simple API to quickly add network monitoring to your app

📋 Requirements

Flutter: >=3.3.0
Dart: >=2.18.0
Android: minSdkVersion 21
iOS: iOS 12.0 or later

📲 Installation

Add the following to your pubspec.yaml:

dependencies:
  network_speed: any

Then run:

flutter pub get

🔧 Setup

Android Setup

No additional setup is required for Android! The plugin automatically adds the necessary permissions to your AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

iOS Setup

For iOS, add the following to your Info.plist file:

<key>NSLocalNetworkUsageDescription</key>
<string>This app needs to access your network to measure internet speed.</string>

🧩 Usage

Import the package

import 'package:network_speed/network_speed.dart';

Get current network type

NetworkType networkType = await NetworkSpeed.getCurrentNetworkType();

switch (networkType) {
  case NetworkType.mobile:
    print('📱 Connected to mobile data');
    break;
  case NetworkType.wifi:
    print('📶 Connected to WiFi');
    break;
  case NetworkType.unknown:
    print('❓ Connection type unknown or offline');
    break;
}

Get current download and upload speeds

// Get instant download speed
double downloadSpeed = await NetworkSpeed.getDownloadSpeed();
print('⬇️ Download speed: $downloadSpeed Mbps');

// Get instant upload speed
double uploadSpeed = await NetworkSpeed.getUploadSpeed();
print('⬆️ Upload speed: $uploadSpeed Mbps');

Get all network information at once

Map<String, dynamic> networkInfo = await NetworkSpeed.getCurrentNetworkSpeed();

print('🌐 Network type: ${networkInfo['networkType']}');
print('⬇️ Download speed: ${networkInfo['downloadSpeed']} Mbps');
print('⬆️ Upload speed: ${networkInfo['uploadSpeed']} Mbps');
print('📶 Signal strength: ${networkInfo['signalStrength']}');

Real-time monitoring with streams

// Start real-time monitoring with updates every second
StreamSubscription<Map<String, dynamic>> subscription = 
    NetworkSpeed.getNetworkSpeedStream(interval: 1000).listen((networkInfo) {
  print('⬇️ Download: ${networkInfo['downloadSpeed']} Mbps | ⬆️ Upload: ${networkInfo['uploadSpeed']} Mbps');
});

// Don't forget to cancel the subscription when no longer needed
subscription.cancel();

Run speed tests

// Show loading indicator
showDialog(context: context, builder: (_) => LoadingDialog());

// Run download speed test
double downloadTestResult = await NetworkSpeed.runDownloadSpeedTest();
print('🔍 Download test result: $downloadTestResult Mbps');

// Run upload speed test
double uploadTestResult = await NetworkSpeed.runUploadSpeedTest();
print('🔍 Upload test result: $uploadTestResult Mbps');

// Hide loading indicator
Navigator.of(context).pop();

// You can also specify a custom URL for testing
double customDownloadTest = await NetworkSpeed.runDownloadSpeedTest(
  testFileUrl: 'https://your-test-file-url.com/file.bin'
);

🧠 How It Works

Android Implementation

Uses Android's ConnectivityManager and NetworkCapabilities APIs for real-time network speed detection
Implements WifiManager for WiFi signal strength
All operations run on background threads to prevent UI freezing

iOS Implementation

Implements URLSessionDataDelegate for accurate download and upload speed measurements
Uses SCNetworkReachabilityFlags for network type detection
All operations run on background queues to prevent UI freezing

📊 Speed Interpretation

Here's a quick guide to interpret the speed results:

Speed (Mbps)	Quality	Suitable For
< 1	🔴 Poor	Basic web browsing
1-5	🟠 Fair	SD video streaming
5-20	🟡 Good	HD video streaming
20-50	🟢 Very Good	4K streaming
50+	🔵 Excellent	Multiple 4K streams

📝 Notes

Speed tests require an active internet connection
Results may vary based on server load and network conditions
For most accurate results, run multiple tests and average the results
The plugin uses minimal resources to measure network speed
All operations run on background threads to prevent UI freezing
