Implementation

@override
(ConfirmModel, 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.yes])) {
      _value = true;
      return (this, Cmd.message(const ConfirmResultMsg(true)));
    }

    if (keyMatches(key, [keyMap.no])) {
      _value = false;
      return (this, Cmd.message(const ConfirmResultMsg(false)));
    }

    if (keyMatches(key, [keyMap.confirm])) {
      return (this, Cmd.message(ConfirmResultMsg(_value)));
    }

    if (keyMatches(key, [keyMap.toggleLeft])) {
      _value = true;
      return (this, null);
    }

    if (keyMatches(key, [keyMap.toggleRight])) {
      _value = false;
      return (this, null);
    }
  }

  return (this, null);
}
