Implementation

@override
(PasswordConfirmModel, Cmd?) update(Msg msg) {
  if (msg is PasswordSubmittedMsg) {
    if (!_inConfirmPhase) {
      // First password entered, move to confirmation
      _inConfirmPhase = true;
      _error = null;
      return (this, _confirmInput.init());
    } else {
      // Confirmation entered, check match
      if (_passwordInput.value == _confirmInput.value) {
        return (
          this,
          Cmd.message(PasswordSubmittedMsg(_passwordInput.value)),
        );
      } else {
        _error = mismatchError;
        _confirmInput.reset();
        return (this, null);
      }
    }
  }

  if (msg is PasswordCancelledMsg) {
    if (_inConfirmPhase) {
      // Go back to first password
      _inConfirmPhase = false;
      _confirmInput.reset();
      _error = null;
      return (this, _passwordInput.focus());
    } else {
      return (this, Cmd.message(const PasswordCancelledMsg()));
    }
  }

  // Delegate to appropriate input
  if (_inConfirmPhase) {
    final (_, cmd) = _confirmInput.update(msg);
    return (this, cmd);
  } else {
    final (_, cmd) = _passwordInput.update(msg);
    return (this, cmd);
