Flutter Package That Tracks Changes in Network Connectivity (WiFi, Celluar, None)

connection_package

Notifies BLoC’s when changes in Network connection changes. Also can report type of connection (WiFi, Celluar, or None)

Useage

See example program. The key class is ConnectionBloc that is provided to a ‘NetworkStatus’-type class (two are provided LiveNetwork and TestNetwork)

The NetworkStatus the BLoC of ConnectionBloc and any time state changes[the event] (Network status performs async listening on network connectivity from the system), it will add a ConnectionChangedEvent to the ConnectionBloc, listerns of the connection block can listen/respond to those changes.

Example

enum NetworkConnectionType {
  Cellular,
  Internet,
  None,
  WiFi,
}

_connectionBloc = ConnectionBloc();
_liveNetwork = LiveNetwork(connectionBloc: _connectionBloc)..listen();

// Current status
_liveNetwork.connectionType().then((NetworkConnectionType value) {
      if (value.toString() != buttonText) {
        setState(() {
          buttonText = value.toString();
        });
      }
    });

// Listening
return BlocBuilder(
      bloc: _connectionBloc,
      builder: (context, state) {
        if (state is ConnectedWifiState) {
          return Center(child: Text('WIFI'));
        }
        if (state is ConnectedCelluarState) {
          return Center(child: Text('Celluar'));
        }
        return Center(child: Text('None'));
);

The …listen() is what starts the listener

Conclusion

Be kind to each other.
