notifications #

A plugin for tracking notifications on the device. Works exclusively for Android.

Installation #

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

Usage #

Android: Register service in the manifest #

The plugin uses an Android system service to track notifications. To allow this service to run the following code should be put inside the Android manifest, between the <application></application> tags.

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

Flutter: Listen to notification events #

Notifications notifications = new Notifications();
StreamSubscription<NotificationEvent> events;
events = notifications.noiseStream.listen(onData);

Where the onData() method handles the incoming NotificationEvents. An example could be:

void onData(NotificationEvent event) => print(event.toString());

Notification Information #

Every time a notification is registered a NotificationEvent is received in Flutter, containing the following attributes:

• packageName [String]: The name of the application which triggered the notification.
• timeStamp [DateTime]: The timestamp at which the notification was received.
  • Alternatively, timeStamp can be converted to a unix timestamp using timeStamp.millisecondsSinceEpoch.
