signUp method

@override Future<AuthUser?> signUp(String email, String password, { String? name, })

Implementation

@override
Future<AuthUser?> signUp(String email, String password, {String? name}) async {
  final String address = _address(email);
  _checkPassword(password);
  // Hashed before the address is looked up, so a taken address does not
  // answer sooner than a free one.
  final String passwordHash = _hasher.hash(password);
  await _ensure();
  if (await _byEmail(address) != null) throw _exists;
  final AuthUser user =
      AuthUser(id: 'acct_${_randomString(24)}', email: address, name: name);
  try {
    await adapter.execute(
      'INSERT INTO $table (id, email, name, password_hash, created_at) '
      'VALUES (?, ?, ?, ?, ?)',
      <Object?>[
        user.id,
        address,
        name,
        passwordHash,
        _clock().toUtc().millisecondsSinceEpoch,
      ],
    );
  } on Object {
    // Another sign-up for this address got there between the lookup and
    // the insert, and the unique key refused this one.
    if (await _byEmail(address) != null) throw _exists;
    rethrow;
  }
  _changes.add(user);
  return user;
}
