Navigate to root screen from nested stack navigato

Question

i am new to react and trying to learn it by myself , i am facing problem in navigating user back to root screen from nested stck navigator screen .

Here is some of my classes :-

index.android.js :-

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  StatusBar,
  View
} from 'react-native';
import {LoginStack} from './login/loginregisterrouter';
import {StackNavigator } from 'react-navigation';
class reactNavigationSample extends Component {
  render(){
    return (
   <LoginStack/>
    );
  }
}
AppRegistry.registerComponent('MssReactDemo', () => reactNavigationSample);

loginregisterrouter :-

import React from 'react';
import {StackNavigator } from 'react-navigation';
import LoginScreen from './LoginScreen';
import RegisterScreen from './RegisterScreen';
import NavigationContainer from './navigationContainer';
export const LoginStack = StackNavigator({
  LoginScreen: {
    screen: LoginScreen,
    navigationOptions: {
      title: 'LoginScreen',
    }
  },
  RegisterScreen: {
    screen: RegisterScreen,
    navigationOptions: ({ navigation }) => ({
      title: 'RegisterScreen',
    }),
  },NavigationContainer: {
        screen: NavigationContainer,

                </Container>
            </ThemeProvider>
    );
  }
}

const styles = StyleSheet.create({
    container: {
        flex: 1,
        backgroundColor: '#F5FCFF',
      },
    header: {
        backgroundColor: '#455A64',
      },
    welcome: {
        fontSize: 20,
        textAlign: 'center',
        margin: 10,
      },
    instructions: {
        textAlign: 'center',
        color: '#333333',
        marginBottom: 5,
      },
  });

The above is the stack architecture i am using inside my application and as you can see that my Main screen is LOGIN screen and i do have option for LOGOUT from application in my Drawer(side menu). What i eaxtly want is that when user click on logout he/she should get redirected to LOGIN screen . i have googled about this and got to know about two ways of doing it , but both the ways are not working for me , may be i am using them in wrong way. so i am here to seek your help .

The two methods are :-

1)

this.props
               .navigation
               .dispatch(NavigationActions.reset(
                 {
                    index: 0,
                    actions: [
                      NavigationActions.navigate({ routeName: 'LoginScreen'})
                    ]
                  }));

2) this.props.navigation.dispatch(NavigationActions.back());

this question may seems silly to you but i am really stuck at this point and just want to know how can i figure this out.Any help would be greatly Appreciated!!!! Thanks in advance.

Answer 1

As per react navigation doc you can go to any stack by following ways: check the following link for more details React-navigation stack action link

1. import { StackActions, NavigationActions } from 'react-navigation';
         const resetAction = StackActions.reset({
          index: 0,
          actions: [NavigationActions.navigate({ routeName: 'Profile' })],
        });
        this.props.navigation.dispatch(resetAction);

2. If you have a stack for profile then you can also go through like this check following link nested react navigation

import { NavigationActions } from 'react-navigation';

const navigateAction = NavigationActions.navigate({
  routeName: 'Profile',

  params: {},

  action: NavigationActions.navigate({ routeName: 'SubProfileRoute' }),
});

this.props.navigation.dispatch(navigateAction);

Answer 2

(React Navigation 5.x) I had the problem of conditionally rendering the Screens like the example in "https://reactnavigation.org/docs/en/auth-flow.html" As I understand, meant that the Stack navigators were not "rendered" and thus are not able to find each other. What I did was the below and in the logout page:

navigation.replace('SplashScreen')

My logic was: SplashScreen (Check for AsyncStorage Token),

if (token){
navigation.navigate('App')
}else{
navigation.navigate('StartScreen')
}

In StartScreen, just navigate to Signin or Register where you go back to App if login is successful.

As a reference,

function AppBottomNavigator(){
  return(
    <AppNavigator.Navigator 
      initialRouteName={'Home'} ...}>
        <AppNavigator.Screen name='A' component={ScreenA}/>
        <AppNavigator.Screen name='B' component={ScreenB}/>
        <AppNavigator.Screen name='C' component={ScreenC}/>
        <AppNavigator.Screen name='D' component={ScreenD}/>
        <AppNavigator.Screen name='E' component={ScreenE}/>
    </AppNavigator.Navigator>
  )
}

export default App stuff...

 ...return(
        <AuthContext.Provider value={authContext}>
          <NavigationContainer>
            <AuthStack.Navigator screenOptions={{headerShown:false}}>
              <>
                <AuthStack.Screen name='SplashScreen' component={SplashScreen}/>
                <AuthStack.Screen name='StartScreen' component={StartScreen} />
                <AuthStack.Screen name='SignIn' component={SignIn} />
                <AuthStack.Screen name='Register' component={Register} />
                <AuthStack.Screen name='App' component={AppBottomNavigator}/>
              </>
            </AuthStack.Navigator>
          </NavigationContainer>
        </AuthContext.Provider>
      )

I am also quite new to this but it worked so if someone else has a safer/tidier/general solution, I would quite like to know, too.

Answer 3

After trying almost everything, I've found the solution that worked for me:

  this.props.navigation.popToTop(); // go to the top of the stack
  this.props.navigation.goBack(null); // now show the root screen

Answer 4

Modal StackNavigator containing a Dismissable StackNavigator

Requires: react-navigation version: 1.0.0

Goal: Navigate from App TabNavigator to Screen 1 to Screen 2 to Screen N and then directly back to App TabNavigator.

Navigation hierarchy:

• RootNavigator StackNavigator {mode: 'modal'}
  • App TabNavigator
    • TabA Screen
    • TabB Screen
    • TabC Screen
  • ModalScreen Screen
  • ModalStack DismissableStackNavigator
    • Screen 1 ModalStackScreen
    • Screen 2 ModalStackScreen
    • Screen N ModalStackScreen

This solution is a sledgehammer. It causes the screen of the default tab in the TabNavigator to unmount and then mount again. If the Screen a tab launching the Modal with the StackNavigator passes some callbacks to update it's state, these callbacks will be called when the Screen is unmounted.

The solution was to add key: null to the reset object:

this.props.navigation.dispatch(NavigationActions.reset({
  index: 0,
  key: null,
  actions: [
    NavigationActions.navigate({ routeName: 'App'})
  ]
}))

I was tipped off by this comment.

(FYI - I got here via your comment asking for help.)
