🚀 Launching My First Flutter Package: Connectivity Manager

As a Flutter developer, I often found myself adding boilerplate code to handle internet connectivity. Every project needed:

• ✅ Check if user is online/offline
• ✅ Show a Snackbar or Dialog when internet is lost
• ✅ Redirect to a No Internet Screen
• ✅ Retry button to recheck connection

I realized this problem is common for every Flutter app, so why not solve it once and for all with a reusable package?
That’s how Connectivity Manager was born. 🎉

📦 What is Connectivity Manager Plus?

Connectivity Manager is an open-source Flutter package that helps you monitor internet connectivity in real-time and show feedback to users in multiple ways:

• Snackbar
• Alert Dialog
• Full Screen
• Or your own Custom UI

It is built on top of connectivity_manager_plus, but provides a plug-and-play solution with ready-made UI and full customization.

✨ Features

• Detect online/offline status instantly
• Show Snackbar, Alert, or Screen out of the box
• Fully customizable text, colors, retry button, and duration
• Provide your own widget or page for complete freedom
• Open-source and community-driven

🛠️ How to Use?

Add to your pubspec.yaml:

dependencies:
  connectivity_manager_plus: ^1.0.0

Initialize in your app:

ConnectivityService().initialize(
  context,
  config: ConnectivityConfig(
    disconnectedText: "🚨 No Internet 😢",
    connectedText: "✅ Back Online 🎉",
    showRetryButton: true,
    onRetry: () => debugPrint("Retry Pressed"),
  ),
);

You can also provide your own custom screen:

ConnectivityConfig(
  customScreenBuilder: (ctx) => Scaffold(
    body: Center(
      child: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: [
          const Icon(Icons.wifi_off, size: 100, color: Colors.red),
          const Text("No Internet Connection"),
          ElevatedButton(
            onPressed: () => debugPrint("Retry from custom screen"),
            child: const Text("Retry"),
          ),
        ],
      ),
    ),
  ),
);

🌍 Open Source & Community Driven

The package is 100% open-source:
👉 GitHub Repo

You are free to:

• Use it in your apps
• Contribute new features
• Report bugs
• Improve the documentation

Together, we can make it even more powerful. 💪

💡 Why I Built This?

As developers, we focus on big features, but small details like a smooth no-internet experience can make or break the user journey.
I wanted to create something that not only helps me, but also helps the community.

This is my first open-source Flutter package — but definitely not the last. 🚀

🙌 Final Thoughts

• ✅ Package published on pub.dev
• ✅ Fully open-source on GitHub
• ✅ Developer-friendly & customizable

If you’re a Flutter developer, give it a try and let me know your feedback.
