isFromCache property
bool
get
isFromCache
Whether the snapshot was created from cached data rather than guaranteed up-to-date server data.
If you called DocumentReference.snapshots or Query.snapshots with
includeMetadataChanges parameter set to true you will receive another
snapshot with isFomCache equal to false once the client has received
up-to-date data from the backend.
Implementation
bool get isFromCache => _delegate.isFromCache;
