such as tabbar ,appbar or others
i want to implement make component as said in the title.
const App = () => {
return (
<NavigationContainer>
<Stack.Navigator initialRouteName="Main" >
<Stack.Screen name="Main" component={MainScreen} options={{ headerShown: false }} />
<Stack.Screen name="Analyze" component={AnalyzeScreen} options={{ headerShown: false }} />
<Stack.Screen name="Write" component={WriteScreen} options={{ headerShown: false }} />
<Stack.Screen name="Result" component={ResultScreen} options={{ headerShown: false }} />
</Stack.Navigator>
</NavigationContainer>
);
};
this is App.js and declared screens.
it dosen't matter. i want just a shared component.
but i don't want tricks each component in each screen.
p.s screens are just a blank screen.
<View style={{flex:1,}}><Text>hello world</Text></View>

I am building an app with React Native and Expo and i am trying to implement authentication in the app but i am getting this error and i can't find a solution.
Basically i have 2 navigation stacks AppStack & AuthStack in my App.js. AppStack will be shown if the user is authenticated and if the user is not authenticated then AuthStack will be shown to the user.
So i am conditionally rendering the stacks with ternary operator as you can see in the App.js code below. The stacks are working fine i mean if user is authenticated then AppStack is shown and if not then AuthStack is shown.
Now the Signin screen is present in AuthStack and when a user logs in successfully he should be navigated to Home screen navigation.navigate("Home") which is present in AppStack. But when a user logs in it throws me this error.
ERROR The action 'NAVIGATE' with payload {"name":"Home"} was not handled by any navigator.
Do you have a screen named 'Home'?
If you're trying to navigate to a screen in a nested navigator, see https://reactnavigation.org/docs/nesting-navigators#navigating-to-a-screen-in-a-nested-navigator.
This is a development-only warning and won't be shown in production
Here is the App.js code:
const AppStack = () => {
return (
<>
<Stack.Navigator>
<Stack.Screen name="Home" component={Home} options={{headerStyle: {backgroundColor: "#000"}, headerTintColor: "white"}} />
<Stack.Screen name="Forgot Password" component={ForgotPwd} options={{headerStyle: {backgroundColor: "#2a454e"}, headerTintColor: "white"}} />
<Stack.Screen name="Check Your Inbox" component={ForgotPwdNext} options={{headerStyle: {backgroundColor: "#00dfc0"}, headerTintColor: "#3a5864"}} />
<Stack.Screen name="Change Password" component={ChangePwd} options={{headerStyle: {backgroundColor: "#e5322b"}, headerTintColor: "white"}} />
</Stack.Navigator>
</>
)
}
const AuthStack = () => {
return (
<>
<Stack.Navigator>
<Stack.Screen name="Welcome" component={Welcome} options={{headerStyle: {backgroundColor: "#1b4152"}, headerTintColor: "white"}} />
<Stack.Screen name="Signin" component={Signin} options={{headerStyle: {backgroundColor: "#5549ab"}, headerTintColor: "white"}} />
<Stack.Screen name="Signup" component={Signup} options={{headerStyle: {backgroundColor: "#26dec0"}, headerTintColor: "#35474f"}} />
<Stack.Screen name="Verify Phone Number" component={VerifyPhone} options={{headerStyle: {backgroundColor: "#d268cc"}, headerTintColor: "white"}} />
<Stack.Screen name="Logged Out" component={LoggedOut} options={{headerStyle: {backgroundColor: "#5a6e7f"}, headerTintColor: "white"}} />
</Stack.Navigator>
</>
)
}
return (
<NavigationContainer style={styles.root}>
<StatusBar style="light" />
{isAuthenticated ? <AppStack /> : <AuthStack />}
</NavigationContainer>
)
}
This exact problem is addressed here.
Your AuthStack doesn't know anything about AppStack and vice versa. Hence navigation.navigate("Home") from AuthStack will fail.
When isAuthenticated is changed React Navigation will automatically navigate to correct screen. This is possible when isAuthenticated state is managed globally using React Context (or by using any state management library like Redux, Zustand etc).
Check this official example which more or less resembles your authentication flow.
You cannot navigate from Signin to Home. You can only navigate between screens that share a parent navigator or grandfather if you have nested navigators. Here is a quote from the doc talking about this specific navigator they created:
Said another way, we can only navigate to routes that have been defined on our navigator — we cannot navigate to an arbitrary component
The common way is to have a way to change isAuthenticated to true in Signin instead of navigating, and the below condition in App.js will do the job. For that you can pass a state setter from App to Signin using a context for example.
{isAuthenticated ? <AppStack /> : <AuthStack />}
somehow managed to solve the error by registering AppStack as a screen in AuthStack and also registering AuthStack as screen in AppStack like this:
const AppStack = () => {
return (
<>
<Stack.Navigator>
<Stack.Screen name="Home" component={Home} options={{headerStyle: {backgroundColor: "#000"}, headerTintColor: "white"}} />
<Stack.Screen name="Forgot Password" component={ForgotPwd} options={{headerStyle: {backgroundColor: "#2a454e"}, headerTintColor: "white"}} />
<Stack.Screen name="Check Your Inbox" component={ForgotPwdNext} options={{headerStyle: {backgroundColor: "#00dfc0"}, headerTintColor: "#3a5864"}} />
<Stack.Screen name="Change Password" component={ChangePwd} options={{headerStyle: {backgroundColor: "#e5322b"}, headerTintColor: "white"}} />
<Stack.Screen name="AuthStack" component={AuthStack} />
</Stack.Navigator>
</>
)
}
NOTE THE LAST SCREEN IN AppStack ABOVE
And same with the AppStack
const AuthStack = () => {
return (
<>
<Stack.Navigator>
<Stack.Screen name="Welcome" component={Welcome} options={{headerStyle: {backgroundColor: "#1b4152"}, headerTintColor: "white"}} />
<Stack.Screen name="Signin" component={Signin} options={{headerStyle: {backgroundColor: "#5549ab"}, headerTintColor: "white"}} />
<Stack.Screen name="Signup" component={Signup} options={{headerStyle: {backgroundColor: "#26dec0"}, headerTintColor: "#35474f"}} />
<Stack.Screen name="Verify Phone Number" component={VerifyPhone} options={{headerStyle: {backgroundColor: "#d268cc"}, headerTintColor: "white"}} />
<Stack.Screen name="Logged Out" component={LoggedOut} options={{headerStyle: {backgroundColor: "#5a6e7f"}, headerTintColor: "white"}} />
<Stack.Screen name="AppStack" component={AppStack} />
</Stack.Navigator>
</>
)
}
But now the problem is i am getting 2 navigation headers When i switch between screens which are in different stacks i mean if i go from one screen to another which are both in same stack then 2 headers doesn't appear, 2 headers only appear when i go from a screen which is in suppose Stack-A to Stack-B
hello guys I am trying to hide the back-arrow navigation button but it does not work
function MyStack(){
return(
<Stack.Navigator
screenOptions={{
headerTitle:null,
headerTransparent:true,
topBar:{
backButton:{
noBorder: true,
backButton: {visible: false},
leftButtons: [],
}
}
}}
>
<Stack.Screen name="Index" component={IndexScreen} />
<Stack.Screen name="drawer" component={Drawer} />
</Stack.Navigator>
)
}
Set headerLeft: null in your <Stack.Screen> or <Stack.Navigator> options like the below example.
function MyStack(){
return(
<Stack.Navigator
screenOptions={{
headerTitle:null,
headerTransparent:true,
headerLeft: null
}}
>
<Stack.Screen options={{headerLeft: null}} name="Index" component={IndexScreen} />
<Stack.Screen name="drawer" component={Drawer} />
</Stack.Navigator>
)
}
i have a stack navigation with some screen i want the header to be hidden in some screen and i achieved that but i have a registration page that i want the header to be visible and to have the back button but its not visible,this is my navigation code
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="Login" component={LoginScreen}
initialParams={{title:null}} options={{
headerShown: false,
headerLeft: null,
gestureEnabled: false}}
/>
<Stack.Screen name="Register" component={RegisterScreen}/>
</Stack.Navigator>
</NavigationContainer>
1) First remove header for entire stack navigator
Choose one of them
I-way
<Stack.Navigator headerMode={'none'}>
II-way
<Stack.Navigator screenOptions={{ headerShown: false }}/>
2) Then show header inside individual screen that you want
<Stack.Screen name="Register" component={RegisterScreen} options={{ headerShown: true}}/>
I wanted to set a custom header to all screens inside a stack navigator except to particular a screen, because I wanted it to have the default header. I know that setting the header property of the options props of the navigator will do the trick to apply the custom header to all the screens, but my question is how to exclude one specific screen and just set it to default?
This is my current implementation for setting the custom header to all screens:
<Stack.Navigator
screenOptions={{
header: () => <CustomHeader />,
}}
>
<Stack.Screen name="Page1" component={Page1} />
<Stack.Screen name="Page2" component={Page2} />
<Stack.Screen name="Page3" component={Page3} />
</Stack.Navigator>
What can I further add to this code to exclude the application of custom header to Page3?
Try this.
<Stack.Navigator>
<Stack.Screen name="Page1" component={Page1} />
<Stack.Screen name="Page2" component={Page2} />
<Stack.Screen options={{ header: () => <CustomHeader /> }} name="Page3" component={Page3} />
</Stack.Navigator>
If anyone was wondering how to do the same for Drawer Navigator here is the solution that I have come up with:
import React, {Fragment} from 'react';
const NavHeader = props => {
// ... NavHeader code goes here
};
export const withHeader = Component => {
return props => {
return (
<Fragment>
<NavHeader {...props} />
<Component {...props} />
</Fragment>
);
};
};
Then in your Drawer you do:
<Drawer.Navigator>
<Drawer.Screen
name={ROUTES.DASHBOARD}
component={withHeader(DashboardContainer)} // <--- Wrap it around component here.
/>
</Drawer.Navigator>
If you want all screens except one to have custom header you wrap up every component with withHeader except one.
You can set Header for all screens. For anyone which you want to avoid you can set headerShown to false.
<NavigationContainer>
<Stack.Navigator
headerMode={'screen'}
screenOptions={{
header: ({navigation}) => <Header navigation={navigation} />,
}}> // This custom Nav Header is for all screen
<Stack.Screen
name="Home"
component={HomescreenTabs}
options={{headerShown: true}}// Will user Header component as Nav Header
/>
<Stack.Screen
name="Editor"
component={Editor}
options={{headerShown: false,}} // No Nav Header component will shown
/>
<Stack.Screen
name="SearchList"
component={SearchList}
options={{headerShown: true}} // Will user Header component as Nav Header
/>
</Stack.Navigator>
</NavigationContainer>
When I set cardStyleInterpolator to forFadeFromBottomAndroid or forVerticalIOS for a Stack.Screen, keyboard immediately dismiss when focusing on TextInput. This not happen for other type.
This only happen for first focus on TextInput.
Here is what's happening:
function RootStack() {
return (
<Stack.Navigator
screenOptions={{
cardStyleInterpolator: CardStyleInterpolators.forHorizontalIOS,
}}
>
<Stack.Screen name="GROUPS" component={GroupsScreen} options={{ headerShown: false }} />
<Stack.Screen name="GROUP" component={GroupScreen} />
<Stack.Screen
name="CREATE_POST"
component={CreatePostScreen}
options={{
headerShown: false,
cardStyleInterpolator: CardStyleInterpolators.forFadeFromBottomAndroid,
}}
/>
<Stack.Screen
name="SELECT_POST_TYPE"
component={AnonymousTypeScreen}
options={{
cardStyle: { backgroundColor: "transparent", opacity: 1 },
headerShown: false,
cardStyleInterpolator: CardStyleInterpolators.forVerticalIOS,
}}
/>
</Stack.Navigator>
);
}
and screen component is just simple component:
return (
<View>
<View style={{ flex: 1 }}>
<TInput />
</View>
</View>
);
I have downgraded dependencies for react-navigation ( native & stack ), because previouslly my code was working, so tried this and it worked.
