[Bug]: PlatformException: NetworkManager::StartListen when using onConnectivityChanged on Windows

[MrRoy121]

Platform

Windows 11 (also occurs on Windows 10)

Plugin

connectivity_plus

Version

7.0.0

Flutter SDK

3.35.7

Steps to reproduce

1. Create a new Flutter project with Windows support: flutter create -p windows my_app
2. Add connectivity_plus: ^6.0.5 to pubspec.yaml
3. Run flutter pub get
4. Replace lib/main.dart with the code sample below
5. Run on Windows: flutter run -d windows
6. Observe the PlatformException being thrown in the console

The error occurs immediately when the app tries to listen to connectivity changes.

Code Sample

**main.dart:**

import 'package:flutter/material.dart';
import 'package:connectivity_plus/connectivity_plus.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Connectivity Test',
      home: const ConnectivityTestScreen(),
    );
  }
}

class ConnectivityTestScreen extends StatefulWidget {
  const ConnectivityTestScreen({Key? key}) : super(key: key);

  @override
  State<ConnectivityTestScreen> createState() => _ConnectivityTestScreenState();
}

class _ConnectivityTestScreenState extends State<ConnectivityTestScreen> {
  late StreamSubscription<List<ConnectivityResult>> _connectivitySubscription;
  String _status = 'Initializing...';

  @override
  void initState() {
    super.initState();
    _setupConnectivityListener();
  }

  void _setupConnectivityListener() {
    try {
      print('🔵 Setting up connectivity listener...');
      _connectivitySubscription = Connectivity().onConnectivityChanged.listen(
        (List<ConnectivityResult> result) {
          setState(() {
            _status = 'Connected: ${result.toString()}';
          });
          print('✅ Connectivity changed: $result');
        },
        onError: (error) {
          print('❌ Error in connectivity stream: $error');
          setState(() {
            _status = 'Error: $error';
          });
        },
      );
      print('✅ Listener setup successful');
    } catch (e) {
      print('❌ Exception during setup: $e');
      setState(() {
        _status = 'Setup failed: $e';
      });
    }
  }

  @override
  void dispose() {
    _connectivitySubscription.cancel();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Connectivity Plus Test')),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text('Status: $_status'),
            const SizedBox(height: 20),
            ElevatedButton(
              onPressed: () async {
                final result = await Connectivity().checkConnectivity();
                print('Single check result: $result');
              },
              child: const Text('Check Connectivity (Single)'),
            ),
          ],
        ),
      ),
    );
  }
}
