getSubscribedTopics method
Returns the list of topics the device is currently subscribed to. On Android/iOS with Firebase this reflects both FCM and local subscriptions. Without Firebase, it reflects locally stored subscriptions only.
Implementation
@override
Future<List<String>> getSubscribedTopics() async {
final result = await methodChannel.invokeListMethod<String>(
'getSubscribedTopics',
);
return result ?? [];
}
