By default, previously read data is immediately available from local sources and is returned without checking the remote source. This is usually the desired behavior, but sometimes you may want to force data to be fetched from the remote source. This can be done by setting the requestType to RequestType.refresh.
final users = await userRepository.getItems(
RequestDetails(
requestType: RequestType.refresh,
),
);
This request will not ask any local sources for data, but will still cache any remote data that is returned.
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.
