NotificationFeedRequest class

A request object for fetching notification feed items.

Android Reference: NotificationFeedRequest

Uses cursor-based pagination matching Android SDK behavior:

• First fetch: no cursor (fetches first page)
• Subsequent fetches: cursor from previous response
• Stops when server returns no cursor (returns empty list)

Example:

final request = (NotificationFeedRequestBuilder()
  ..setLimit(20)
  ..setReadState(FeedReadState.unread)
  ..setCategory('promotions'))
  .build();

final items = await request.fetchNext(
  onSuccess: (items) => print('Got ${items.length} items'),
  onError: (e) => print('Error: ${e.message}'),
);
