How to call action using NavigationAction??? Here if the user doesn't have a token, it goes back to the initial page. I want to reset(initialize) the MainTabNavigator . componentWillReceiveProps(nextProps) { if ( nextProps.token == undefined || _.isNil(nextProps.token) ) { const backAction = NavigationActions.back({ key: null }) nextProps.navigation.dispatch(backAction); Here is MainTabNavigator. I added route to reset everything when 'MyCompleteReset' is triggered. export default TabNavigator({ ........ }); const navigator = MainTabNavigator; const defaultGetStateForAction = navigator.router

I'm trying to used react-navigation but I can not get it to work when I move each screens' components into multiple files. I always get this error: "The component for route 'Home' must be a React component". This error doesn't happen if I move all of the code into one file, so I'm not sure what the difference is. Here is my App.js: import React from 'react'; import { StackNavigator } from 'react-navigation'; import { AppRegistry, StyleSheet, Text, View, TouchableHighlight } from 'react-native'; import { HomeScreen } from './screens/HomeScreen'; import { JoinScreen from './screens/JoinScreen';

I want to hide the Header and the TabNavigator tabs onScroll. How do I do that? I want to hide them onScroll and show them on ScrollUp. My code: import React, { Component } from 'react'; import { View, Text, ScrollView, StyleSheet, TouchableOpacity} from 'react-native'; class ScrollTest extends Component { render(){ const { params } = this.props.navigation.state; return( <View style={styles.container}> <ScrollView> <View style={{styles.newView}}><Text>Test</Text></View> <View style={{styles.newView}}><Text>Test</Text></View> <View style={{styles.newView}}><Text>Test</Text></View> <View style={

I am looking desperately for a possibility to check if a previous screen exists in ReactNavigation. Using this.props.navigation.goBack() returns false if no previous route exists, but I can not use it because if a previous route exists I get redirected. Is there a possibility to check if I opened the app instead of navigated from another screen to the Home screen? Thank you. I am not using Redux. It would make such stuff easier but I would like to avoid using it at the moment. What could be a solution (not sure that it's the best one) would be to spend in the param object the previous screen.

This is my drawerNavigation : const DashboardStack = StackNavigator({ Dashboard: { screen: Dashboard }, }, { headerMode: 'screen', }); const DetailsformStack = StackNavigator({ Detailsform: { screen: Detailsform }, }, { headerMode: 'none' }); const OtpStack = StackNavigator({ Otp: { screen: Otp, drawer: { lockMode: 'locked-closed' } }, }, { headerMode: 'none' }); const MobilenumberStack = StackNavigator({ Mobilenumber: { screen: Mobilenumber }, }, { headerMode: 'none' }); const DrawerviewStack = StackNavigator({ Drawerview: { screen: Drawerview }, }, { headerMode: 'none' }); const
