connectivity_watcher

Connectivity Watcher is a robust Flutter package designed to monitor internet connectivity and network availability status in real-time. This ensures that your app can effectively manage and respond to changes in connectivity, providing a seamless user experience.

Getting started

First, add connectivity_watcher as a dependency in your pubspec.yaml file

dependencies:
  flutter:
    sdk: flutter
  connectivity_watcher: ^[version]

Import the package

import 'package:connectivity_watcher/connectivity_watcher.dart';

🚀 What's New

1. Curl Inteceptor for dio

   Now you can get curl for your api request inside your console with dio

   Dio dio = Dio();
   dio.interceptors.add(CurlInterceptor());
   

2. Api call with internet status

   Execute API tasks seamlessly by verifying internet connectivity beforehand.

   ConnectivityWatcher().makeApiCall(
     apiCall: (internetStatus) async {
       if (internetStatus) {
         Dio dio = Dio();
   
         Response data = await dio.post(
           "https://jsonplaceholder.typicode.com/posts",
           data: {
             "title": 'foo',
             "body": 'bar',
             "userId": 1,
           },
         );
       }
     },
   );
   

Usage 🚀

What if i have to use a custom screen which my designer provided for no internet 😅!

The Custom method

Wrap Your MaterialApp With ConnectivityWatcherWrapper and pass the connection style as custom and then pass your custom widget to offline widget as show thats it.

Widget build(BuildContext context) {
    return ConnectivityWatcherWrapper(
      navigationKey: navigatorKey,
      connectivityStyle: NoConnectivityStyle.CUSTOM,
      noInternetText: Text(
        "Testing message", // Any Message 
        style: TextStyle(color: Colors.red),
      ),

      offlineWidget: CustomNoInternetWrapper(
        builder: (context) {
          return CustomNoInternet();
        },
      ),
      // Place your custom no internet Widget
      builder: (context, connectionKey) {
        return MaterialApp(
            navigatorKey: navigatorKey,
            debugShowCheckedModeBanner: false,
            title: 'Connectivity_Watcher',
            theme: ThemeData(
              primarySwatch: Colors.blue,
            ),
            home: LoginDemo());
      },
    );
  }

Note: The package will automatically remove the custom widget if internet is back but in case its not removed you can use the follwing method to remove it

bool hasRemoved = await   ConnectivityWatcher.().hideNoInternet();
if(hasRemoved){
 // your code after internet is back
    }
    else{
       print("No Internet");
    }

The Inbuild Styles

Wrap Your MaterialApp With ConnectivityWatcherWrapper and pass the connection style

1. SnackBar Style

  Widget build(BuildContext context) {
    return ConnectivityWatcherWrapper(
      connectivityStyle: NoConnectivityStyle.SNACKBAR,
      builder: (context, connectionKey) {
        return MaterialApp(
            navigatorKey: connectionKey, // add this key to material app 
            debugShowCheckedModeBanner: false,
            title: 'Connectivity_Watcher',
            theme: ThemeData(
              primarySwatch: Colors.blue,
            ),
            home: LoginDemo());
      },
    );
  }

2. Alert

  Widget build(BuildContext context) {
    return ConnectivityWatcherWrapper(
     connectivityStyle: NoConnectivityStyle.ALERT,
      builder: (context, connectionKey) {
        return MaterialApp(
            navigatorKey: connectionKey, // add this key to material app 
            debugShowCheckedModeBanner: false,
            title: 'Connectivity_Watcher',
            theme: ThemeData(
              primarySwatch: Colors.blue,
            ),
            home: LoginDemo());
      },
    );
  }

Check Internet Status

bool hasInternet = await ConnectivityWatcher().getConnectivityStatus();

Run Apis on internet status changes

If your are in situation where you have to perform certain operation based on the internet status changes you can use ConnectivityWatcher().subscribeToConnectivityChange()

// create a variable to store steam subscription
late StreamSubscription<ConnectivityWatcherStatus> subscription;

// Just like any other stream you can use the listen method and initialize stream in init state 
@override
  void initState() {
    // TODO: implement initState
    super.initState();
    ConnectivityWatcher().subscribeToConnectivityChange(
        subscriptionCallback: ((stream) {
      subscription = stream.listen((event) {
        if (event == ConnectivityWatcherStatus.connected) {
          // Internet is Connected
        } else {
          // Internet is disconnected
        }
      });
    }));
  }
