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,
navigationOptions: ({ navigation }) => ({
title: 'NavigationContainer', header: null,
}),
},
});

import React, { Component } from 'react';
import {
AppRegistry,

View
} from 'react-native';
import {EasyRNRoute,} from '../parent';
import {StackNavigator } from 'react-navigation';
export default class NavigationContainer extends Component {
render(){
return (
<EasyRNRoute/>
);
}
}
parent.js :-
import React, { Component } from 'react';
import {
StyleSheet,
Text,

} from 'react-native';
import App from './app';
import DrawerMenu from './Drawer/drawer-toolbar-android';
import BookmarkView from './Pages/bookmark';
import ClientView from './Pages/client';
import InfoView from './Pages/info';
import SettingsView from './Pages/setting';
import { DrawerNavigator, StackNavigator } from 'react-navigation';
export const stackNavigator = StackNavigator({
Info: { screen: InfoView },
Settings: {screen: SettingsView },
Bookmark: {screen: BookmarkView },
Connections: {screen: ClientView},
}, {
headerMode: 'none'
});
export const EasyRNRoute = DrawerNavigator({
Home: {
screen: App,
},
Stack: {
screen: stackNavigator
}
}, {
contentComponent: DrawerMenu,
contentOptions: {
activeTintColor: '#e91e63',
style: {
flex: 1,
paddingTop: 15,
}
}
});

} from 'react-native';
import { NavigationActions } from 'react-navigation'
import { COLOR, ThemeProvider, Toolbar, Drawer, Avatar } from 'react-native-material-ui';
import Container from '../Container';
import LoginScreen from '../login/LoginScreen';
const uiTheme = {

paddingTop: 20,
},
},
avatar: {
container: {
backgroundColor: '#333'
}
}
};
export default class DrawerMenu extends Component {
constructor(props, context) {
super(props, context);
this.state = {
active: 'people',
};
}
handleLogoutPress = () => {
// AsyncStorage.setItem('SignedUpuser', '');
this.props
.navigation
.dispatch(NavigationActions.reset(
{
index: 0,
actions: [
NavigationActions.navigate({ routeName: 'LoginScreen'})
]
}));
// this.props.navigation.dispatch(NavigationActions.back());
};
_setInfoActive() {
this.setState({ active: 'info' });
}
render() {
return (

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

instructions: {

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.
