react-navigation

I am using createMaterialTopTabNavigator from react-navigation and trying to customize the tab bar by adding some components on top of it. As you can see in its guide here: https://reactnavigation.org/docs/en/material-top-tab-navigator.html#docsNav there is an option called tabBarComponent that can be passed to create your own tab bar. However, it completely overrides the tab bar which is not what I want. I'd like to add a custom component at the top of the tab bar and then have the default tabs with their labels underneath. Can anyone show me an example of how to add a component to the tab

I’ve observed Back button logic works seeing the sequence of screens in the stack. I’ve a Drawer navigator placed inside stack navigator. On top of the stack I’ve Splash screen. On Dashboard when I press back button it takes me to splash screen. How can I remove splash screen from stack after entering in the app, So when I press back button Dashboard it will EXIT the app instead of taking to SPLASH SCREEN. /* @flow */ import React from "react"; import { Platform, Text } from "react-native"; import { Root } from "native-base"; import { StackNavigator, DrawerNavigator} from "react-navigation";

I am creating an app using React Native for ios. Instead of having an active tintColor I want to have two little triangles (another image/icon) which appears when you are on the selected tab. It is important that the center y axis of the triangles is = to the y axis of the bottom of the tabbar image and that the tab icon is in the center of the triangles as seen below. At the moment I have the tab bar, the icons and navigation working - I just don't know how to make the triangles appear: ICON TABS import React, {Component} from 'react'; import { Image, TouchableOpacity, View } from 'react

I am using react navigation. I want to show drawer over the header of the screen. Currently my header is not hiding below drawer when I open the drawer. import React from 'react'; import { View, Text, StyleSheet } from 'react-native'; import { createStackNavigator, createDrawerNavigator } from 'react-navigation'; import CategoryScreen from './CategoryScreen'; import ProductsScreen from './ProductsScreen'; import CartScreen from './CartScreen'; const drawerScreens = createDrawerNavigator ({ Category: CategoryScreen, Products: ProductsScreen, },{ initialRouteName: 'Category' } ) export default

I'm working on a React Native application that also use Redux and I want to write tests with Jest. I'm not able to mock the "navigation" prop that is added by react-navigation. Here is my component: import React from 'react'; import { connect } from 'react-redux'; import PropTypes from 'prop-types'; import { Text, View } from 'react-native'; const Loading = (props) => { if (props.rehydrated === true) { const { navigate } = props.navigation; navigate('Main'); } return ( <View> <Text>Loading...</Text> </View> ); }; Loading.propTypes = { rehydrated: PropTypes.bool.isRequired, navigation:

I noticed that views in StackNavigation show the header title but if I set those same screens in a TabNavigation it doesn't show a header. It only shows a header if I wrap a StackNavigation either around each tab, or wrap the TabNavigation nested inside a StackNavigation. Why don't screens in TabNavigation show a header - is that expected behavior? If so, is it better to have a StackNavigation in each tab, or one big StackNavigation around the TabNavigation? // tabs navigation doesn't show a header title in each screen const TabsNavigator = TabNavigator({ Home: { screen:HomeScreen, }, Profile:

I am developing a trivia game, I am using react-navigation to handle navigation, I have 3 components, (newGame, Questions, Results ) I don't want the user to go back to the questions from the results page if the no. of questions has been exhausted, however, pressing the back button ( Android Hardware ) is taking him back to the questions. I then tried to handle the hardware back button like so: componentWillMount() { this.props.gameState(true); BackHandler.addEventListener('hardwareBackPress', () => { if (this.props.gamePlaying) { // Currently set to true. I will set it to false again on
