getIdentityIndexByNameMulti method
Batch retrieval of identity indexes for multiple exact names.
Single RPC via polkadart's multiIdentitiesNames. Order is preserved and
the result is padded to names.length (same contract as
getIdentityIndexOfMulti).
Implementation
@override
Future<List<int?>> getIdentityIndexByNameMulti(List<String> names) async {
nameMultiLookupCount++;
return names.map((n) => _reservedNameMap[n]).toList();
}
