switchNavigator with react-navigation 5

The switchNavigator was removed because you can do the exact same stuff now with the help of rendering components conditionally.

import React from 'react';
import {useSelector} from "react-redux";
import {NavigationContainer} from "@react-navigation/native";

import { AuthNavigator, MyCustomNavigator } from "./MyCustomNavigator";

const AppNavigator = props => {
    const isAuth = useSelector(state => !!state.auth.access_token);

    return (
        <NavigationContainer>
            { isAuth && <MyCustomNavigator/>}
            { !isAuth && <AuthNavigator/>}
        </NavigationContainer>
    );
};
export default AppNavigator;

The lines inside the NavigationContainer fully replace the old switch navigator.

I had also used SwitchNavigator of Navigator 4 then after migrating other pages to Navigator 5, i tried to move authentication part to Navigator 5. I could not achieve SwitchNavigator functionality using Navigator 5. Then decided to use "Compatibility layer" provided in Navigation API 5. https://reactnavigation.org/docs/5.x/compatibility
Hope below code will useful for you.

import { createStackNavigator } from '@react-navigation/stack'
import { NavigationContainer } from '@react-navigation/native';
import { createSwitchNavigator } from "@react-navigation/compat";
import { createCompatNavigatorFactory } from '@react-navigation/compat'
 const AppStack = createCompatNavigatorFactory(createStackNavigator)(
      { screen: Home },
      {headerMode:'none'}
 );
 const AuthStack = createCompatNavigatorFactory(createStackNavigator)({ screen:Login });
const SwitchNavigator= createSwitchNavigator(
      {
    Starter: AuthValidation,
    App: AppStack,
    Auth: AuthStack
  },
  {
    initialRouteName:'Starter'
  }
);
export default function App (){
  
    return(
      <NavigationContainer>
          <SwitchNavigator/>
      </NavigationContainer>
    );
}

Here AuthValidation validate for token and depending on value it navigate to "Login" or "Home" Page

_checkAuthetication = async() =>{
  const isUserAuthenticated= await AsyncStorage.getItem("isAuthenticated");
  this.props.navigation.navigate(isUserAuthenticated ? 'App':'Auth');
}
