Implementation

@override
(DestructiveConfirmModel, Cmd?) update(Msg msg) {
  if (msg is KeyMsg) {
    final key = msg.key;

    if (keyMatches(key, [keyMap.cancel])) {
      return (this, Cmd.message(const ConfirmCancelledMsg()));
    }

    if (keyMatches(key, [keyMap.confirm])) {
      if (isMatch) {
        return (this, Cmd.message(const ConfirmResultMsg(true)));
      } else if (_input.isNotEmpty) {
        _error = 'Input does not match "$confirmText"';
      }
      return (this, null);
    }

    // Handle backspace
    if (key.type == KeyType.backspace) {
      if (_input.isNotEmpty) {
        _input.removeLast();
        _error = null;
      }
      return (this, null);
    }

    // Handle character input
    if (key.runes.isNotEmpty) {
      final text = String.fromCharCodes(key.runes);
      for (final g in uni.graphemes(text)) {
        final cp = uni.firstCodePoint(g);
        if (cp >= 32 && cp != 127) {
          _input.add(g);
          _error = null;
        }
      }
      return (this, null);
    }
  }

  return (this, null);
