SnapshotMetadata.fromCache property

True if the snapshot was created from cached data rather than guaranteed up-to-date server data. If your listener has opted into metadata updates (via SnapshotListenOptions) you will receive another snapshot with fromCache set to false once the client has received up-to-date data from the backend.

Signature:

readonly fromCache: boolean;
