putMeta abstract method
Updates the metadata of AtKey.key if it is already present. Otherwise creates a new key without a value.
By default namespace that is used to create the AtClient instance will be appended to the key. phone@alice will be saved as
phone.persona@alice where 'persona' is the namespace. If you want to save by ignoring the namespace set AtKey.metadata.namespaceAware
to false.
update:meta:phone@alice:ttl:60000
var metaData = Metadata()..ttl = 60000
var key = AtKey()..key='phone'
..metadata=metaData
putMeta(key);
update:meta:phone@alice:ttr:120000:ccd:true
var metaData = Metadata()..ttr = '120000'
..ccd = true
var key = AtKey()..key='phone'
..metadata=metaData
putMeta(key);
If you want to set both value and metadata please use put
Implementation
Future<bool> putMeta(AtKey key);
