React Native navigation problem with asyc storage - javascript

I have a really strange problem and so far could not identify the possible weak points.
I have a firebase & react-native application with a nested login.
The problem is the navigation. The drawer and the stack navigation works fine, except for the login screen.
When I try to login and the isSignedIn variable becomes true, the screen is not changing for the home screen. It remains the login screen. However, on the console, I see the authentication was successful. If I go back to the code and click a save in the Navigation file (which was posted here), the forced reload seems to solve the problem and I can see the home screen. But this is not automatically.
So confused.
export default function Navigator() {
const user = firebase.auth().currentUser;
const [isSignedIn, setIsSignedIn] = useState(false)
useEffect( () => {
user ? setIsSignedIn(true) : setIsSignedIn(false)
if (isSignedIn) storeData(user)
})
const storeData = async (value) => {
try {
await AsyncStorage.setItem('userObject', JSON.stringify(value))
alert('Data successfully saved to the storage')
} catch (e) {
alert('Failed to save the data to the storage')
}
}
return (
<NavigationContainer>
<Stack.Navigator initialRouteName="Login">
{isSignedIn ? (
<>
<Stack.Screen name='loggedInUserNavigationStack' component={loggedInUserNavigationStack} options={{headerShown: false}}>
</Stack.Screen>
</>
) : (
<Stack.Screen name="Log in" component={LoginScreen} options={{headerShown: false}} />
)}
</Stack.Navigator>
</NavigationContainer>
);
}
function loggedInUserNavigationStack() {
return (
<Drawer.Navigator initialRouteName="mainContentNavigator" drawerContent={ props => <DrawerContent {...props} /> }>
<Drawer.Screen name="mainContentNavigator" component={mainContentNavigator} options={{ title: 'Home' }} />
<Drawer.Screen name="About" component={AboutScreen} options={{ title: 'About' }}/>
<Drawer.Screen name="Archive" component={ArchiveScreen} options={{ title: 'Archive' }}/>
<Drawer.Screen name="Profile" component={ProfileScreen} options={{ title: 'Profile' }} />
<Drawer.Screen name="Sign Out" component={SignOutScreen} options={{headerShown: false}}/>
</Drawer.Navigator>
);
}
function mainContentNavigator() {
return (
<Stack.Navigator initialRouteName="HomeScreen">
<Stack.Screen name="Home" component={HomeScreen} options={
({ navigation }) => {
return {
headerLeft: () => <Header navigation={navigation} />
}
}
} />
<Stack.Screen name="CertainHabbit" component={CertainHabbit} options={({ route }) => ({ title: route.params.name })} />
</Stack.Navigator>
);
}

Firebase automatically tries to restore the signed-in user when you load the page. But since this requires an async call to the server, it may take some time. Right now, by the time your const user = firebase.auth().currentUser runs, the user hasn't been authenticated yet. And by the time the authentication finishes, your code isn't aware of it.
The solution is to use an auth state listener, as shown in the first snippet of the documentation on determining the signed in user. For you that'd be something like this:
useEffect( () => {
firebase.auth().onAuthStateChanged((user) => {
setIsSignedIn(!!user);
if (user) storeData(user)
});
})

Please try,
<NavigationContainer>
<Stack.Screen name="Login" component={LoginScreen} options={{headerShown: false}} />
</NavigationContainer>
You have given initial route name has initialRouteName="Login"
I do see a space in the stack screen.

Try the following for return part:
return isSignedIn ? (
<NavigationContainer>
<Stack.Screen name='loggedInUserNavigationStack' component={loggedInUserNavigationStack} options={{headerShown: false}} />
</NavigationContainer>
):(
<NavigationContainer>
<Stack.Screen name="Login" component={LoginScreen} options={{headerShown: false}} />
</NavigationContainer>
)

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.

onAuthStateChanged not navigating me to home screen

I have been struggling with this for days now... When I try to login it does not automatically navigate me to home screen, unless I close and open app.
I am working with 3 separate components. However after I register once, this issue doesn't occur it only happens with new accounts.
const [userAuth, setUserAuth] = useState()
useEffect(() => {
const unsubscribe = auth.onAuthStateChanged(user => {
user && auth.currentUser?.emailVerified ? setUserAuth(true) : setUserAuth(false)
})
return unsubscribe
})
return (
<Provider store={store}>
<NavigationContainer>
<Drawer.Navigator>
<Drawer.Screen
name='main'
component={userAuth ? MainDrawer : AuthStack}
/>
</Drawer.Navigator>
</NavigationContainer>
</Provider>
This is my MainDrawer.js
export default function MainDrawer() {
return (
<Drawer.Navigator drawerContent={props => <DrawerScreen {...props} />}>
<Drawer.Screen
name='drawer'
component={HomeStack}
options={{ headerShown: false }}
/>
</Drawer.Navigator>
)
}
This is my HomeStack.js
<Stack.Navigator initialRouteName='home'>
<Stack.Screen name='home' component={TabNav}/>
<Stack.Screen name='about' component={AboutUs}/>
<Stack.Screen name='faq' component={FaqScreen}/>
<Stack.Screen name='userTerms' component={TermsScreen} />
<Stack.Screen name='privacy' component={PrivacyScreen} />
</Stack.Navigator>
I believe the issue is where you're trying to call onAuthStateChanged, it should be auth().onAuthStateChanged(...). Also, I would change it a little bit
useEffect(() => {
const unsubscribe = auth().onAuthStateChanged(firebaseUserResult => {
firebaseUserResult && firebaseUserResult.emailVerified ? setUserAuth(true) : setUserAuth(false)
})
return unsubscribe
})

How to send params data to the screen which is in drawer stack. in react native

How to send Params data to the screen which is in drawer stack.
here is my code from login screen I want to send loginAs data to the homeScreen which is in MyDrawer stack.
onPress={() => this.props.navigation.navigate("MyDrawer", {loginAs : `${this.state.nature}`})}
here is my MyDrawer stack
function App({ navigation }) {
return (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="loginScreen" component={loginScreen} options={{headerShown: false}} />
<Stack.Screen name="MyDrawer" component={MyDrawer} options={{headerShown: false}} />
</Stack.Navigator>
</NavigationContainer>
);
}
function MyDrawer({ navigation }) {
return (
<Drawer.Navigator initialRouteName="homeScreen">
<Drawer.Screen name="homeSreen" component={homeScreenStack}
options={{drawerLabel: 'Home',}}
/>
</Drawer.Navigator>
);
}
You navigate directly to your homeScreen like this
onPress={() => this.props.navigation.navigate("homeScreen", {loginAs : `${this.state.nature}`})}
And then in your homeScreenStack component you get your params like you'd noramlly do
const loginAs = navigation.params?.loginAs;
Note: you have a typo in the name property of your Drawer.Screen you typed homeSreen instead of homeScreen so be aware of that.

Stack navigator header disappear and can't use navigation.navigate(

I have this navigation structure:
const TabNavigator = () => {
return (
<Tab.Navigator>
<Tab.Screen name='dashboard' component={Dashboard} />
<Tab.Screen name='info' component={Info} />
</Tab.Navigator>
);
};
const App = () => {
return (
<SafeAreaProvider>
<Provider store={store}>
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name='main' component={TabNavigator} />
<Stack.Screen name='market' component={Market} />
<Stack.Screen name='cart' component={Cart} />
<Stack.Screen name='ongoingdelivery' component={OngoingDelivery} />
</Stack.Navigator>
</NavigationContainer>
</Provider>
</SafeAreaProvider>
);
};
the first screen shown is "Dashboard" whose live inside the "TabNavigator". After that, inside "Market" component, on a button, I use props.navigation.navigate('market') and I successfully navigate to market, inside Market component, I navigate to "Cart" the same way. So when I am on "Cart" screen, I try to use props.navigation.navigate('ongoingdelivery') and nothing happens. Not even an error is thrown. But if I instead of "ongoingdelivery" I navigate back to market, it works. why?

Trying to create a React Navigation Drawer with custom content

I am trying to create a React Navigation drawer with custom content (I want to put profile information, probably not any links). I am having a ton of trouble doing so.
Here's my basic stack/drawer:
const Drawer = createDrawerNavigator();
function DrawerNav() {
return (
<ScrollView>
<DrawerItems {...props} />
<Text>Test Content</Text>
</ScrollView>
);
}
const Stack = createStackNavigator();
function App() {
return (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="Login" component={Login} options={{
headerShown: false
}} />
<Stack.Screen name="Detail" component={Detail} />
<Stack.Screen name="Chat" component={Chat} />
<Stack.Screen name="Leagues" component={Leagues} />
<Stack.Screen name="Profile" component={Profile} />
<Stack.Screen name="Home" component={Home} options={{
headerRight: (navigation) => (
<TouchableOpacity onPress={(navigation) => navigation.dispatch(DrawerActions.toggleDrawer())}>
<EvilIcons name="navicon" size={50} color="black" />
</TouchableOpacity>
),
headerLeft: () => (
null
),
}} />
<Stack.Screen name="CommForm" component={CommForm} />
</Stack.Navigator>
</NavigationContainer>
);
}
All I want, literally all I want, is a sidebar that I can toggle by pressing the <TouchableOpacity> button above with custom content inside of it.
I am able to do this with React Native Side Menu, but it seems like if I am using React Navigation, I should learn how to do it with this library, however it seems very difficult to do what I am trying to do.
How do I create a sidebar with custom content with React Navigation? I primarily want to use Stack navigation.
I would do something like this:
function CustomDrawerContent(props) {
return (
<DrawerContentScrollView {...props}>
<DrawerItem label="..." />
// ...
</DrawerContentScrollView>
);
}
function StackNavigator({navigation}) {
return (
<Stack.Navigator>
<Stack.Screen
name="Home"
component={Home}
options={{
headerRight: () => (
<Button title="press" onPress={() => navigation.toggleDrawer()} />
),
}}
/>
// Your other screens...
</Stack.Navigator>
);
}
function DrawerNavigator({navigation, route}) {
return (
<Drawer.Navigator
drawerContent={(props) => <CustomDrawerContent {...props} />}>
<Drawer.Screen name="Stack" component={StackNavigator} />
</Drawer.Navigator>
);
}
const App = () => {
return (
<NavigationContainer>
<DrawerNavigator />
</NavigationContainer>
);
};
So you can set the drawer navigation to be your main navigator and your stack navigation to be a screen of the drawer navigation. This way you can toggle the drawer without first navigating to it.
For creating custom drawer content you can pass a component to the drawerContent on the drawer navigator.
If you're going to use DrawerContentScrollView and/or DrawerItem like I've done in this example, be sure to import it from '#react-navigation/drawer'; .
Look at the documentation for more information https://reactnavigation.org/docs/drawer-navigator/#providing-a-custom-drawercontent.
