passwordSalt property
The user's password salt (base64-encoded), only if Firebase Auth hashing
algorithm (SCRYPT) is used. If a different hashing algorithm had been used to
upload this user, typical when migrating from another Auth system, this will
be an empty string. If no password is set, this is null. This is only
available when the user is obtained from _BaseAuth.listUsers.
Implementation
final String? passwordSalt;
