javascript - 如何隐藏特定屏幕上的底部标签栏（react-navigation 3.x）

Question

我使用了 createBottomTabNavigator，但我无法在特定屏幕上隐藏底部应用栏

const StackHome = createStackNavigator(
  {
    Home: Home,
    Autor: Autor,
    Publicacion: Publicacion,
    Comentarios: {
      screen: Comentarios,
      navigationOptions:{
        // this should do the work, but it doesn't
        tabBarVisible: false
      }
    }
  }
);

最后我得到了一个可行的解决方案，组件是这样的

import { createStackNavigator } from "react-navigation";
import Home from "./Home";
import Autor from "./Profile";
import Publicacion from "./Publicacion";
import Comentarios from "./Comentarios";

const StackHome = createStackNavigator({
  Home: Home,
  Autor: Autor,
  Publicacion: Publicacion,
  Comentarios: Comentarios
});

// This does the trick
StackHome.navigationOptions = ({ navigation }) => {
  let tabBarVisible;
  if (navigation.state.routes.length > 1) {
    navigation.state.routes.map(route => {
      if (route.routeName === "Comentarios") {
        tabBarVisible = false;
      } else {
        tabBarVisible = true;
      }
    });
  }

  return {
    tabBarVisible
  };
};

export default StackHome;
