📡 network_checker_plus #

A lightweight and efficient Flutter plugin to check the network status of the device. Easily determine whether the user is connected to the internet and what type of network they’re using — Wi-Fi, mobile data, or none. Now with support for network speed, signal strength, and real-time connectivity stream.

✨ Features #

✅ Check if the device is connected to the internet

✅ Detect the type of connection (Wi-Fi, Mobile, or None)

✅ Estimate network speed (e.g., ping a server or download a small file)

✅ Measure signal strength (Wi-Fi)

✅ Real-time stream of connectivity status

🚀 Getting Started #

1️⃣ Add Dependency #

Add this to your pubspec.yaml:

dependencies:
  network_checker_plus: ^1.0.6

Then run:

flutter pub get

2️⃣ Import the Package #

import 'package:network_checker_plus/network_checker_plus.dart';

🔍 Usage #

✅ Check Internet Status #

final bool isConnected = await NetworkCheckerPlus.isConnected();
print('Connected: \$isConnected');

📡 Get Connection Type #

final String type = await NetworkCheckerPlus.getConnectionType();
print('Connection Type: \$type');

Possible values:

• 'wifi'
• 'mobile'
• 'none'
• 'unknown'

⌛️ Estimate Network Speed #

final String speed = await NetworkCheckerPlus.getNetworkSpeed();
print('Network Speed: \$speed');

Possible values:

• "Excellent"
• "Good"
• "Moderate"
• "Poor"
• "No Connection"

📶 Get Signal Strength (Wi-Fi only) #

final int strength = await NetworkCheckerPlus.getSignalStrength();
print('Signal Strength: \$strength/4');

Signal levels range from 0 (Weak) to 4 (Excellent).

⏳ Listen to Connectivity Changes #

NetworkCheckerPlus.connectivityStream.listen((event) {
  print('Connectivity Changed: \$event');
});

Events:

• 'connected'
• 'disconnected'

🛡 Permissions #

📱 Android #

Ensure you add the following permissions in android/app/src/main/AndroidManifest.xml:

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

Some features (e.g., signal strength) may require ACCESS_FINE_LOCATION on newer Android versions.

🧪 Example #

Clone this repo and run the example app to see it in action:

cd example
flutter run

💡 Roadmap #

• ✅ Check network connection
• ✅ Detect connection type (Wi-Fi or Mobile)
• ✅ Estimate basic network speed
• ✅ Measure Wi-Fi signal strength
• ✅ Real-time listener for network changes
• ❌ Support signal strength for mobile networks
