Watching realtime data amounts to calling watch, watchByIds, or watchList on a Repository whose SourceList contains a `WatchableSource.
final stream = userRepository.watchList(
RequestDetails(filter: ActiveUsersFilter()),
);
It is the job of a your WatchableSource to negotiate how to fulfill this watch with your server. For a ready-to-go Firestore solution, see pkg:data_layer_firestore.
Understand how sources declare operation capabilities via supportedOperations and how SourceList respects them.
FirestoreAdminSource connects google_cloud_firestore for server-side Dart applications to a SourceList.
FirestoreSource seamlessly connects Cloud Firestore streams to a SourceList.
Perform untyped Firestore document merges using the raw method on Firestore sources.
Cached data is mapped uniquely per request hash (RequestDetails with specific filter and pagination), supporting a powerful request-based caching behavior.
The SourceList class manages the delegation of read/write attempts to various configured Sources, with a read-thru cache system prioritizing local Sources.
