# Flutter Web Package (connectivity_web)

A Flutter web package, that allows you to check internet status anytime or listen to event changes. There is a pre-built widget [OnOffWidget] to make things simple.

### Check internet status anytime

```dart

bool isOnline = ConnectivityWeb().isOnline.value;

```

### Use the pre-built widget to display internet status in the screen

```dart

OnOffWidget(

  online: Icon(Icons.signal_wifi_4_bar, color: Colors.green),

  offline: Icon(Icons.signal_wifi_off, color: Colors.red)

);

```

### Listen events

```dart

ConnectivityWeb().isOnline.observe((isOnline) {

  if (isOnline.newValue != isOnline.oldValue) print(isOnline.newValue);

});

```

## You can find the full example [here](https://github.com/emanuel-braz/connectivity_web/tree/master/example) with Observer, Reaction, StreamController and OnOffWidget.
