Notifications

A plugin for monitoring notification on Android.

Install

Add notifications as a dependency in pubspec.yaml. For help on adding as a dependency, view the documentation.

Add the following snippet of code inside the application tag of yours AndroidManifest.xml

    ...
    <service
        android:label="notifications"
        android:name="dk.cachet.notifications.NotificationListener"
        android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
        <intent-filter>
            <action android:name="android.service.notification.NotificationListenerService" />
        </intent-filter>
    </service>
</application>

Usage

All incoming data points are streamed with a StreamSubscription which is set up by calling the listen() method on the notificationStream stream object.

Given a method onData(NotificationEvent event) the subscription can be set up as follows:

Notifications _notifications;
StreamSubscription<NotificationEvent> _subscription;
...
void onData(NotificationEvent event) {
    print(event);
}

void startListening() {
    _notifications = new Notifications();
    try {
      _subscription = _notifications!.notificationStream!.listen(onData);
    } on NotificationException catch (exception) {
      print(exception);
    }
}

The stream can also be cancelled again by calling the cancel() method:

  void stopListening() {
    _subscription?.cancel();
  }

The NotificationEvent provides:

• the title
• the message
• package name
• timestamp

of each notification.
