React Navigation Nested Tab.Navigator - Show InitialRoute not in Tabs

Using React-Navigation in my app, I want the initialRoute to be the "Home" component with the BottomTabNavigator shown. But I do not want Home to be one of the tabs. Adding initialRouteName="Home" shows Home as the initial route but does not show the tabs. Without initialRoute I get the tabs but not the Home Screen as the initial.
I have a nested React Navigation set up like this:
const MyTabs = () =>{
return (
<Tab.Navigator>
<Tab.Screen name="About" component={AboutStack} />
<Tab.Screen name="Setting" component={SettingStack} />
</Tab.Navigator>
);
}
const MyStack = () => {
return (
<Stack.Navigator initialRouteName="Home">
<Stack.Screen name="Tabs" component={MyTabs} />
<Stack.Screen name="Home" component={HomeStack} />
</Stack.Navigator>
);
}
This seems like it should be relatively simple to implement, but I've searched far and wide for another similar question and I've tried a number of different nesting setups to no avail.
Running: "#react-navigation/stack": "^6.0.7", or "latest"
Here is a snack of the full test code: https://snack.expo.dev/#dezpo/nestednavigator_homepage_notintab
Any help greatly appreciated.

You can set the initial route in the MyStack navigator to the Home screen with the initialRouteName prop:
const MyStack = () => {
return (
<Stack.Navigator initialRouteName="Home">
<Stack.Screen name="Tabs" component={MyTabs} />
<Stack.Screen name="Home" component={HomeStack} />
</Stack.Navigator>
);
}
Then, in the HomeStack component, you can navigate to the Tabs screen within the Home component:
const HomeStack = ({ navigation }) => {
return (
<View>
<Text>Home Screen</Text>
<Button
title="Go to Tabs"
onPress={() => navigation.navigate("Tabs")}
/>
</View>
);
};
This way, the Home component will be the initial route and when the user clicks the "Go to Tabs" button, the Tabs screen with the Tab.Navigator will be displayed.

Actually I got this sorted... couldn't have been easier
tabBarItemStyle: { display: "none" }
🤦‍♂️
so my final navigators looked like this with "Home" as one of my BottomTabs
const MyTabs = () =>{
return (
<Tab.Navigator >
<Tab.Screen name="Home" component={HomeStack}
options={{
tabBarItemStyle: { display: "none" },
}}/>
<Tab.Screen name="About" component={AboutStack} />
<Tab.Screen name="Setting" component={SettingStack} />
</Tab.Navigator>
);
}
const MyStack = () => {
return (
<Stack.Navigator initialRouteName="Home"
screenOptions={{
headerShown: false
}}>
<Stack.Screen name="Tabs" component={MyTabs} />
</Stack.Navigator>
);
}
Updated Snack
Seems like there is probably a better solution out there but this does the trick for now.

useEffect doesn't work when switching screens

Hi I am still new to react-native and has been trying to create an app.
My stuck is that I don't know why useEffect doesn't work when switching screens by react-navigation-bottom-tab.
Below is my HomeScreen.js where I wrot useEffect to fetch all data from Firestore.
As you can see I wrote two useEffects because I thought it'd work.
The first one was thought to fetch data when I switch to Home from like ProfileScreen.
import {
View,
FlatList,
StyleSheet,
} from "react-native";
import { RideCard } from "./RideCard";
import { OneTouchFilter } from "./OneTouchFilter";
import { useFirestoreContext } from "../../contexts/FirestoreContext";
import { useEffect } from "react";
export const HomeScreen = ({ navigation }) => {
console.log("HomeScreen.js useEffect");
const { selectedBoardType, cityFromText, cityToText, fetchRides, rides } =
useFirestoreContext();
useEffect(() => {
fetchRides();
}, []);
useEffect(() => {
fetchRides();
}, [selectedBoardType, cityFromText, cityToText]);
return (
<View style={styles.inner}>
<OneTouchFilter />
<FlatList
data={rides}
renderItem={(itemData) => (
<RideCard
ride={itemData.item}
index={itemData.index}
id={itemData.item.id}
numOfRides={rides.length}
/>
)}
/>
</View>
);
};
App.js
this is a file where react-navigation-bottom-tab placed in.
import React, { useContext } from "react";
import { StyleSheet } from "react-native";
import { NavigationContainer, DefaultTheme } from "#react-navigation/native";

};
export default function App() {
const Stack = createStackNavigator();
// タブ移動の設定を新規追加

const Tab = createBottomTabNavigator();
// 新規追加
// - 移動を関数に持たせて、タブ移動の設定で利用

const Home = () => {
return (
<Stack.Navigator>
<Stack.Screen
options={{ headerShown: false }}
name="Home"
component={HomeScreen}
/>
</Stack.Navigator>
);
};
const Post = () => {
return (
<Stack.Navigator
headerMode="screen"
screenOptions={{ headerShown: false }}
>
<Stack.Screen name="Post" component={PostScreen} />
{/* <Stack.Screen name="詳細" component={DetailsScreen} /> */}
</Stack.Navigator>
);
};
const Profile = () => {
return (
<Stack.Navigator
headerMode="screen"
screenOptions={{ headerShown: false }}
>
<Stack.Screen name="Profile" component={ProfileScreen} />
{/* <Stack.Screen name="詳細" component={DetailsScreen} /> */}
</Stack.Navigator>
);
};
return (
<AuthContextProvider>
<FirestoreContextProvider>
<FormContextProvider>
<NativeBaseProvider>
<NavigationContainer theme={MyTheme}>
<Tab.Navigator
screenOptions={({ route }) => ({
tabBarIcon: ({ focused, color, size }) => {
let iconName;
// icon swithcer which depends on the route name
if (route.name === "Home") {
iconName = focused ? "ios-home" : "ios-home";
} else if (route.name === "Post") {
iconName = focused ? "ios-add" : "ios-add";
} else if (route.name === "Profile") {
iconName = focused ? "md-person" : "md-person";
}
return (
<Ionicons name={iconName} size={size} color={color} />
);
},
})}
tabBarOptions={{
activeTintColor: "rgb(0, 110, 182)",
inactiveTintColor: "gray",
}}
>
<Tab.Screen name="Home" component={Home} />
<Tab.Screen name="Post" component={Post} />
<Tab.Screen name="Profile" component={Profile} />
</Tab.Navigator>
</NavigationContainer>
</NativeBaseProvider>
</FormContextProvider>
</FirestoreContextProvider>
</AuthContextProvider>
);
}

It's because, even though you switch screens, the other screen is not unmounted --- it's still in memory but not visible. This is a design decision of react-navigation intended for better performance (it doesn't have to reload the screen when you go back, as it's already there). Since it is not unmounted, when the user returns to it, it just triggers a rerender of the already-instantiated component, so the effect does not run.
What you need to use instead is useFocusEffect which is an effect bound to if the screen is in focus.

Found screens with the same name nested inside one another

I want to achieve a native stack navigator for each tab. However I want different Stack navigator files for each tab. So I created different files but i'm getting a warning in the console:
Found screens with the same name nested inside one another. Check:
Home, Home > Home
This can cause confusing behavior during navigation. Consider using
unique names for each screen instead. at
node_modules/#react-navigation/core/src/BaseNavigationContainer.tsx:364:14 in React.useEffect$argument_0
Also the the Home screen is nested inside Home screen.I tried changing the name of the Home from Home to Homescreen component still the issue persists.
Here are the functions in my files:
Home.js
function Home({ navigation }) {
return (
<View style={styles.screen}>
<Text>Home screen!</Text>
<Button title="Details" onPress={() => navigation.navigate("Details")} />
</View>
);
}
Details.js
const Details = (props) => {
return (
<View>
<Text>Details will appear here!</Text>
</View>
);
};
HomeStackScreen.js
import { createNativeStackNavigator } from "#react-navigation/native-stack";
import HomeScreen from "../screens/Home";
import DetailsScreen from "../components/Details";
const HomeStack = createNativeStackNavigator();
function HomeStackScreen() {
return (
<HomeStack.Navigator>
<HomeStack.Screen name="Home" component={HomeScreen} />
<HomeStack.Screen name="Details" component={DetailsScreen} />
</HomeStack.Navigator>
);
}
AppNavigator.js
import { createBottomTabNavigator } from "#react-navigation/bottom-tabs";
import { NavigationContainer } from "#react-navigation/native";
import HomeStackScreen from "./HomeStackScreen";
const Tab = createBottomTabNavigator();
function AppNavigator() {
return (
<NavigationContainer>
<Tab.Navigator
screenOptions={({ route }) => ({
tabBarIcon: ({ focused, color, size }) => {
let iconName;
if (route.name === "Home") {
iconName = focused ? "ios-home" : "ios-home-outline";
}
{/*other routes*/}
})}
>
<Tab.Screen name="Home" component={HomeStackScreen} />
{/*other tabs*/}
</Tab.Navigator>
</NavigationContainer>
);
}

Show BottomNavigation once the user is logged

I want to use BottomNavigation to navigation between screens actually its working fine with BottomNavigation.SceneMap({...})
but the BottomNavigation its being showing in every screens, i only want to show once the user is logged. after click on login button
import React from 'react'
import { Provider } from 'react-redux'
import { createStore } from 'redux'
import userReducer from './src/reducers/user'
import { NavigationContainer } from '#react-navigation/native'
import { BottomNavigation, Text } from 'react-native-paper'
import { createStackNavigator } from '#react-navigation/stack'
import { theme } from './src/core/theme'
import {
StartScreen,
Dashboard,
GroupScreen,
InviteScreen,
CreateGroup,
} from './src/screens'
const Stack = createStackNavigator()
const store = createStore(userReducer)
export default function App() {
const [index, setIndex] = React.useState(0)
const [routes] = React.useState([
{ key: 'music', title: 'Music', icon: 'queue-music' },
{ key: 'albums', title: 'Albums', icon: 'album' },
])
const one = () => (
<NavigationContainer>
<Stack.Navigator
initialRouteName="StartScreen"
>
<Stack.Screen name="StartScreen" component={StartScreen} />
<Stack.Screen name="Dashboard" component={Dashboard} />
</Stack.Navigator>
</NavigationContainer>
)
const two = () => (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="InviteScreen" component={InviteScreen} />
</Stack.Navigator>
</NavigationContainer>
)
const renderScene = BottomNavigation.SceneMap({
music: one,
albums: two,
})
return (
<Provider store={store} theme={theme}>
<BottomNavigation
navigationState={{ index, routes }}
onIndexChange={setIndex}
renderScene={renderScene}
/>
</Provider>
)
}
EDIT by answers:
i did this when i pressed the button login i need to redirect to dashboard but dashboard is in mytabs
function MyTabs() {
return (
<Tab.Navigator>
<Tab.Screen name="Dashboard" component={Dashboard} />
</Tab.Navigator>
)
}
does not render nothing, i just to copy any example from here https://reactnavigation.org/docs/bottom-tab-navigator/ any of those render in my local, i am using EXPO
for example this
import * as React from 'react';
import { Text, View } from 'react-native';
import { NavigationContainer } from '#react-navigation/native';
import { createBottomTabNavigator } from '#react-navigation/bottom-tabs';
function HomeScreen() {
return (
<View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
<Text>Home!</Text>
</View>
);
}
function SettingsScreen() {
return (
<View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
<Text>Settings!</Text>
</View>
);
}
const Tab = createBottomTabNavigator();
function MyTabs() {
return (
<Tab.Navigator>
<Tab.Screen name="Home" component={HomeScreen} />
<Tab.Screen name="Settings" component={SettingsScreen} />
</Tab.Navigator>
);
}
export default function App() {
return (
<NavigationContainer>
<MyTabs />
</NavigationContainer>
);
}
the wrong is display:none

You need to put your BottomNavigation in another stack that has loginScreen side by side.
Try using createBottomTabNavigator
import { createBottomTabNavigator } from '#react-navigation/bottom-tabs';
const Tab = createBottomTabNavigator();
function MyTabs() {
return (
<Tab.Navigator>
<Tab.Screen name="Home" component={HomeScreen} />
<Tab.Screen name="Settings" component={SettingsScreen} />
</Tab.Navigator>
);
}
<NavigationContainer>
<Stack.Navigator initialRouteName="loginScreen">
<Stack.Screen name="loginScreen" component={LoginScreen} />
<Stack.Screen name="main" component={MyTabs} />
</Stack.Navigator>
</NavigationContainer>

Take what you already have with MyTabs() and create a LoginScreen and then do the following. You will need to detect whether the user is present. If there is a user, then show the main screen, if not show the login screen.
<>
<Stack.Navigator screenOptions={{ headerShown: false }}>
{user ? (
<Stack.Screen name="Main" component={MainStack} />
) : (
<Stack.Screen name="Login" component={LoginStack} />
)}
</Stack.Navigator>
</>

The best way is to do like this:
<NavigationContainer>
{user !== null ? <RootNavigator /> : <AuthNavigator />}
</NavigationContainer>
The user is a useState.
The NavigationContainer has 2 options. If the user is logged it shows the RootNAvigator with the bottomNavigation, if not it shows the authentication flow.

React Native show header and back button on drawer navigation screen

I just add drawer navigation and works fine, but in options, there is not a headerShown as Stack has.
I created a few screen examples, and use tapbar, stack and drawer in the same file.+
I searched on some YouTubes and there is not a specific explanation
Thank you.
You can see my current app: GIF HERE
HomeStack
const HomeStack = createStackNavigator();
function HomeStackScreen() {
return (
<HomeStack.Navigator>
<HomeStack.Screen
name="Home"
component={Home}
options={{ headerShown: false }}
/>
<HomeStack.Screen name="Details" component={DetailsScreen} />
</HomeStack.Navigator>
);
}
Drawer
const Drawer = createDrawerNavigator();
const Tab = createBottomTabNavigator();
export default function App() {
return (
<NavigationContainer>
<Drawer.Navigator initialRouteName="Home">
<Drawer.Screen name="Home" component={MainScreen} />
<Drawer.Screen
name="Leaderboards"
component={Leaderboards}
options={{
drawerIcon: (config) => <AntDesign size={23} name="user" />,
}}
/>
</Drawer.Navigator>
</NavigationContainer>
);
}
````

Drawer screen has no header option. You can either make your own header component for your Leaderboards screen or nest a stack navigator that contains the Leaderboards screen within your drawer screen and customize the header through the options properties.
