listForNamespace abstract method
The enrollments authorised for namespace (the caller's own enrollment
must hold at least read access — the atServer gates the verb), each with
the key package to seal to. excludeEnrollmentIds drops revoked
enrollments before they ever enter a roster.
Implementation
Future<List<NamespaceMember>> listForNamespace(
String namespace, {
Set<String> excludeEnrollmentIds = const {},
});
