put method

@override Future<bool> put(AtKey atKey, dynamic value, {bool isDedicated = false, PutRequestOptions? putRequestOptions})

Updates value of AtKey.key is if it is already present. Otherwise creates a new key. Set AtKey.sharedWith if the key has to be shared with another atSign. Set AtKey.metadata.isBinary if you are updating binary value e.g image,file. 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. Additional metadata can be set using AtKey.metadata

isDedicated is currently ignored and will be removed in next major version

putRequestOptions allows additional options to be provided. See PutRequestOptions

From at_client v3.0.55 lowercase will be enforced on all AtKey types AtKeys will now be actively converted to lowercase in at_client The values(AtValue) will however continue to be case-sensitive

update:phone@alice [phone]
  var key = AtKey()..key='phone'
  put(key,'[phone]');
update:public:phone@alice [phone]
  var metaData = Metadata()..isPublic=true;
  var key = AtKey()..key='phone'
            ..metadata=metaData
  put(key,'[phone]');
update:@bob:phone@alice [phone]
  var metaData = Metadata()..sharedWith='@bob';
   var key = AtKey()..key='phone'
                  ..metadata=metaData
  put(key,'[phone]');
update:@alice:phone.persona@alice [phone]
  var key = AtKey()..key='phone'
            ..sharedWith='@alice'
  put(key, '[phone]');
update:@alice:phone@alice [phone]
  var metaData = Metadata()..namespaceAware=false
  var key = AtKey()..key='phone'
           sharedWith='@alice'
  put(key, '[phone]');
update:@bob:phone.persona@alice [phone]
  var key = AtKey()..key='phone'
            sharedWith='@bob'
   put(key, '[phone]');

Starting version 3.0.0 isDedicated is deprecated Throws AtValueException if invalid value type is found

Throws AtKeyException if invalid key or metadata is found

Throws AtEncryptionException if encryption process fails

Throws SelfKeyNotFoundException if self encryption key is not found

Throws AtPrivateKeyNotFoundException if encryption private key is not found

Throws AtPublicKeyNotFoundException if encryption public key is not found

  // If the value is neither String nor List<int> throw exception
  if (value is! String && value is! List<int>) {
    throw AtValueException(
        'Invalid value type found ${value.runtimeType}. Expected String or List<int>');
  }
