如何使用React Navigation 5在Action Creators中导航到屏幕？

Question

在 React Navigation 5 Auth Flow它说当条件状态改变时，屏幕会自动导航。

• 我已经设置了当isAuthenticated的状态改变为true时，屏幕将导航到HomeScreen。
• 控制台中没有出现任何错误。isAuthenticated确实改变了totrue，但是在状态改变后屏幕没有导航到HomeScreen。
• 我还尝试了在动作创建者中使用{NavigationActions}和{CommonActions}这样的替代方法来强制导航，但都不起作用。

AuthStackNav.js

import React from 'react';
import { connect } from 'react-redux';
import {createStackNavigator} from '@react-navigation/stack';
import AuthScreen from '../screens/AuthScreen';
import HomeScreen from '../screens/HomeScreen';

const AuthStackNav = ({isAuthenticated}) => {
    const AuthStack = createStackNavigator();

    return (        
        <AuthStack.Navigator initialRouteName='Auth'>
        {
            isAuthenticated ?
            <AuthStack.Screen name='Home' component={HomeScreen} />                
            :
            <AuthStack.Screen  name='Auth' component={AuthScreen} />      
        }                       
                         
        </AuthStack.Navigator>
        
    );
};
const mapStateToProps = ({isAuthenticated}) => {
    return {isAuthenticated};
};
export default connect(mapStateToProps, null)(AuthStackNav);

userActions.js

import {LOGIN_WITH_FACEBOOK} from './types';
import {NavigationActions} from 'react-navigation'; 
import { CommonActions } from '@react-navigation/native'; 

export const loginWithFacebook = () => (dispatch) => {        
    dispatch({ type: LOGIN_WITH_FACEBOOK, payload: {isAuthenticated: true} });   
    dispatch(NavigationActions.navigate({routeName:'Home'}));
    dispatch( CommonActions.navigate({ name: 'Home' }) );                                           
};

userReducer.js

import {LOGIN_WITH_FACEBOOK} from '../actions/types.js';

const initialState = {
    isAuthenticated: false    
};

const userReducer = (state=initialState, action) => {
    switch(action.type){
        case LOGIN_WITH_FACEBOOK: 
            return {...state, ...action.payload};
        default: 
            return state;
    }
}
export default userReducer;

AuthScreen.js

import React from 'react';
import {Text, View, StyleSheet, Image, TouchableOpacity, SafeAreaView} from 'react-native';
import { connect } from 'react-redux';
import {loginWithFacebook} from '../actions/userActions';

const AuthScreen = ({loginWithFacebook}) => {    

    return (
        <View style={styles.screenContainer}>                

                <TouchableOpacity                     
                    activeOpacity={0.5}
                    onPress={loginWithFacebook}
                >  Facebook Login</TouchableOpacity> 

        </View>  
    );
};
const mapDispatchToProps = {
    loginWithFacebook
};
export default connect(null, mapDispatchToProps)(AuthScreen);

AppNav.js

import React from 'react';
import {NavigationContainer} from '@react-navigation/native';
import AuthStackNav from './AuthStackNav';

const AppNav = () => {
    return (
        <NavigationContainer>
            <AuthStackNav />
        </NavigationContainer>
    );
};

export default AppNav;

我能够用这个来解决它 指南.

RootNavigation.js

import * as React from 'react';

export const navigationRef = React.createRef();

export function navigate(name, params) {
  navigationRef.current?.navigate(name, params);
}

AppNav.js

import { navigationRef } from './RootNavigation.js';
const AppNav = () => {
    return (
        <NavigationContainer ref={navigationRef} >
            <AuthStackNav />
        </NavigationContainer>
    );
};

export default AppNav;

userActions.js

export const loginWithFacebook = () => (dispatch) => {        
    dispatch({ type: LOGIN_WITH_FACEBOOK, payload: {isAuthenticated: true} });   
    RootNavigation.navigate('Home');                                    
};
