Get Start

1. Register the service in the manifest

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

<service android:name="im.zoe.labs.flutter_notification_listener.NotificationsHandlerService"
    android:label="Flutter Notifications Handler"
    android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
    <intent-filter>
        <action android:name="android.service.notification.NotificationListenerService" />
    </intent-filter>
</service>

If you want to start the service after reboot, also should put the following code.

<receiver android:name="im.zoe.labs.flutter_notification_listener.RebootBroadcastReceiver"
    android:enabled="true">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

2. Init the plugin and add listen handelr

Future<void> initPlatformState() async {
    NotificationsListener.initialize();
    NotificationsListener.receivePort.listen((evt) => onData(evt));
}

void onData(NotificationEvent event) {
    print(event.toString());
}

3. Check permission and start the service

void startListening() async {
    print("start listening");
    var hasPermission = await NotificationsListener.hasPermission;
    if (!hasPermission) {
        print("no permission, so open settings");
        NotificationsListener.openPermissionSettings();
        return;
    }

    var isR = await NotificationsListener.isRunning;

    if (!isR) {
        await NotificationsListener.startService();
    }

    setState(() => started = true);
}

Please check the ./example/lib/main.dart for more detail.
