Usage

Functional approach

This plugin provides two streams:

• isConnected that shows whether the device is REALLY connected to the network or not.
• onConnectivityChanged that it will not let you know about state of the REAL network connection. It only shows connectivity state.

Also for one time check could be used following methods:

• checkConnection() that is working like isConnected, but returns Future<bool> instread of Stream<bool>.
• checkConnectivity() that is working like onConnectivityChanged, but returns Future<ConnectivityStatus> instread of Stream<ConnectivityStatus>.

There are no more methods (they are working only on Android/iOS/macOS):

• getWifiName() - Obtains the wifi name (SSID) of the connected network.
• getWifiBSSID() - Obtains the wifi BSSID of the connected network.
• getWifiIP() - Obtains the IP address of the connected wifi network.

They are removed to wifi_info_flutter.

Migration guide:

If you don't use any of the above APIs, your code should work as is. In addition, you can also remove NSLocationAlwaysAndWhenInUseUsageDescription and NSLocationWhenInUseUsageDescription in ios/Runner/Info.plist

If you use any of the above APIs, you can find the same APIs in the wifi_info_flutter plugin. For example, to migrate getWifiName, use the new plugin:

final WifiInfo _wifiInfo = WifiInfo();
final String wifiName = await _wifiInfo.getWifiName();

Widget approach

As an alteration to funcitonal approach could be used ConnectivityBuilder widget as follows:

ConnectivityBuilder(
  builder: (context, isConnected, status) => Row(
    mainAxisSize: MainAxisSize.min,
    children: <Widget>[
      Icon(
        isConnected == true
            ? Icons.signal_wifi_4_bar
            : Icons.signal_wifi_off,
        color: isConnected == true ? Colors.green : Colors.red,
      ),
      const SizedBox(width: 8),
      Text(
        '$status',
        style: TextStyle(
          color: status != ConnectivityStatus.none
              ? Colors.green
              : Colors.red,
        ),
      ),
    ],
  ),
)
