HarmonyOS 自定义弹窗弹出的情况下，侧滑屏的时候不执行弹窗的关闭

需要设置onWillDismiss，能阻止自定义dialog弹出时，侧滑失效：

inputDialogController: CustomDialogController = new CustomDialogController({
  builder: InPutDialog({}),
  customStyle: true,
  alignment: DialogAlignment.Bottom,
  isModal: false,
  onWillDismiss: () => {
    return false;
  }
})
