internet_connectivity_checker

The connectivity package and other similar packages only provides information if there is a network connection, but not if the network is connected to the Internet. That's why the internet_connectivity_checker package helps you easily manage widgets dynamically based on the device's internet access.

🧑‍💻 Getting started

flutter pub add internet_connectivity_checker

🛠️ Usage

Simply import package:internet_connectivity_checker/internet_connectivity_checker.dart' and use the ConnectivityBuilder widget. It takes a builder and an optional parameter, interval(Duration object) which is the time interval to wait between each internet connectivity verification; default is 5 seconds.

Exemple

class Hello extends StatelessWidget {
  const Hello({super.key});

  @override
  Widget build(BuildContext context) {
    return ConnectivityBuilder(
      builder: (status) {
        bool connected = status == ConnectivityStatus.online;
        return Text(connected ? "Online" : "Offline");
      },
    );
  }
}

A more complete example.

ConnectivityBuilder(
  builder: (ConnectivityStatus status) {
    if (status == ConnectivityStatus.online) {
      return Container(
        decoration: BoxDecoration(
          color: Colors.green,
          borderRadius: BorderRadius.circular(15),
        ),
        child: Center(child: Text("Online", style: kTextStyle)),
      );
    } else if (status == ConnectivityStatus.offline) {
      return Container(
        decoration: BoxDecoration(
          color: Colors.red,
          borderRadius: BorderRadius.circular(15),
        ),
        child: Center(child: Text("Offline", style: kTextStyle)),
      );
    } else { // status == ConnectivityStatus.checking
      return const Center(
        child: SizedBox(
          width: 25,
          height: 25,
          child: CircularProgressIndicator(strokeWidth: 2),
        ),
      );
    }
  },
),

You can also use the ConnectivityChecker().stream stream, provided be the package, to handle the logic yourself.

class Foo extends StatelessWidget {
  const Foo({super.key});

  @override
  Widget build(BuildContext context) {
    return StreamBuilder(
      stream: ConnectivityChecker(interval: const Duration(seconds: 10)).stream,
      builder: (context, snapshot) {
        if (snapshot.hasData && (snapshot.data as bool) == true) {
          return const Text("Online");
        } else if (snapshot.connectionState == ConnectionState.waiting) {
          return const Center(child: CircularProgressIndicator());
        } else {
          return const Text("Offline");
        }
      },
    );
  }
}
