NetworkChecker is a Flutter widget that monitors the internet connection status and displays a customizable retry screen when no internet connection is available. It provides an easy way to ensure your app handles network outages gracefully.

Features #

• Monitors internet connection in real-time.
• Displays a default retry screen when the network is unavailable.
• Customizable retry button and retry screen UI.
• Built-in periodic connection checking.

Installation #

Add this to your package's pubspec.yaml file:

yaml

dependencies:
   network_checker: latest_version

Then, run:

flutter pub get

Usage #

Wrap the NetworkChecker widget around your main app or any specific part of the widget tree you want to monitor for connectivity:

Basic Usage #

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

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

class MyApp extends StatelessWidget {

const MyApp({super.key});

@override
Widget build(BuildContext context) {
 return MaterialApp(
  home: NetworkChecker(
   child: Scaffold(
    appBar: AppBar(title: const Text('Network Checker Example')),
     body: const Center(child: Text('You are online!')),
       ),
     ),
    );
  }
 }

Custom Retry Screen #

For full customization, use the retryUI property to provide a custom retry screen:

NetworkChecker(
  child: MyApp(),
  retryUI: Center(
    child: Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: [
        const Text('No Connection', style: TextStyle(fontSize: 20)),
        const SizedBox(height: 10),
        IconButton(
          icon: const Icon(Icons.refresh),
          onPressed: () => print('Retry!'),
        ),
      ],
    ),
  ),
)
