react-native 如何监听HarmonyOS侧滑返回或者点击系统返回键

BackHandler.addEventListener('hardwareBackPress', function () { 
  // TODO eg: TurboModule.back() 
  return true; 
});

onBackPress(): boolean | undefined { 
  // NOTE: this is required since `Ability`'s `onBackPressed` function always 
  // terminates or puts the app in the background, but we want Ark to ignore it completely 
  // when handled by RN 
  return this.rnAbility?.onBackPress(); 
}
