I have a Tab Navigator with 3 screens: Home, Camera, and Profile. I then have a stack navigator which references the tab navigator, and have a screen in this stack navigator called Camera2.
const Navigation = () => {
return (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="Home" component={TabNavigator} />
<Stack.Screen name="Camera2" component={Camera2Screen} />
</Stack.Navigator>
</NavigationContainer>
);
};
const TabNavigator = () => {
return (
<Tab.Navigator backBehavior="history" initialRouteName="Home">
<Tab.Screen name="Home" component={HomeScreen} />
<Tab.Screen name="ToCamera" component={ToCameraScreen} />
<Tab.Screen name="Profile" component={ProfileScreen} />
</Tab.Navigator>
);
};
Suppose I start at the Home screen, then navigate to the Camera screen by selecting the camera tab. Then in the Camera screen I use navigation.replace("Camera2"). At this point, in the Camera2 screen I would want the navigation history to look like [Home, Camera2] since the Camera screen had been removed from history. However, what I end up seeing is [Camera2].
After doing some research I realized this was happening since the tab navigator acts as a single screen in the stack navigator, so seperate tabs show up as a single screen in navigation history. So if I remove the Camera screen from history it essentially removes all Tab Navigator screens (including the Home screen).
I realize this is the expected behaviour but I was wondering how I can get the desired behaviour.

I have a stack navigator with react router, using #react-navigation/native-stack. My home screen is a map, and I have a few menu components:
export const App = () => {
return (
<NavigationContainer>
<Stack.Navigator initialRouteName="Home">
<Stack.Screen
name="Home"
options={{ headerShown: false }}
component={Home}
/>
<Stack.Screen
name="SignIn"
component={SignIn}
/>
</Stack.Navigator>
</NavigationContainer>
)
}
Home is the map component, and SignIn, as well as some other components, are menu components that take over the screen when navigated to, pushing Home out of the way, as expected.
I want to be able to 'navigate' to another component at a certain route, call it Overlay. When routed here, I want to show the home screen, with an Overlay component laid over the top of part of the Home component, while still maintaining interactivity with the part of the Home screen that is not covered. However, if I do this:
<Stack.Navigator initialRouteName="Home">
<Stack.Screen
name="Home"
options={{ headerShown: false }}
component={Home}
/>
<Stack.Screen
name="Overlay"
component={Overlay}
/>
</Stack.Navigator>
Then the Home screen moves away, and is replaced by Overlay.
How can I show a component overlaid over the top of my Home screen when the user is routed to a certain route? This is something easily done with react-router, but I'm not sure if there is a parallel in react-navigation. Is react-navigation not the right approach for this? Is it better to conditionally render the Overlay component based on a state/redux variable?
I'm using React Navigation 5.
At the top I have a Drawer navigator, with the following screens:
<Drawer.Navigator>
<Drawer.Screen name="One" component={StackNavigatorOne} />
<Drawer.Screen name="Two" component={StackNavigatorTwo} />
<Drawer.Screen name="Three" component={StackNavigatorThree} />
<Drawer.Navigator/>
Within StackNavigatorOne, I have a stack navigator,
<Stack.Navigator>
<Stack.Screen name="Screen1" component={Screen1} />
<Stack.Screen name="Screen2" component={Screen2} />
<Stack.Screen name="Screen2" component={Screen3} />
</Stack.Navigator>
In the StackNavigatorOne, the default order of screens is Screen1, Screen2, and Screen3, so that when this stack navigator is called, it shows Screen1 by default. I don't want to change this order.
However, from the Drawer Navigator, when a user clicks, DrawerScreen One, I want the user to go to Screen2 in StackNavigatorOne. Is it possible to do?
In React Navigation, you can check Nested Navigators.
Select your root component One first and then select the component inside the Stack Navigator.
navigation.navigate('One', {
screen: 'Screen2',
params: {
...
},
});
I assume, Clicking on back will go to your screen from where you navigated. If you want to go to Screen1, use lazy option as false. I've not tested this in drawerNavigator but for bottom navigator we used lazy option as false.
I am building a project in react native. I want to use a bottom tab navigator, but the problem i have is that it automatically shows all screens in the navigator.
I want to hide one of the screens from the bar on the bottom.
Try this on your screen that needs to be hidden
const Tab = createBottomTabNavigator();
<Tab.Navigator>
...
<Tab.Screen
name="screen2"
component={screen2}
options={{ tabBarButton: () => null }}
/>
...
</Tab.Navigator>
I am creating a nested navigation container in react-native and the stack looks like this:
-Main Navigation Container:
- Home
- Market Navigation Container:
- Market
- Cart
- About
When I go to home or about and go back, it works properly. However, when I go back from Market or cart (Which I expect to go to the Home page) it shows an error saying:
The action 'POP' with payload {"count":1} was not handled by any navigator.
Is there any screen to go back to?
This is a development-only warning and won't be shown in production.
This is my code for the main navigation container:
<NavigationContainer independent={true}>
<Stack.Navigator>
<Stack.Screen options={myOptions} name="Home" component={Home} />
<Stack.Screen
options={{ headerShown: false }}
name="MarketNavigation"
component={MarketNavigation}
/>
<Stack.Screen options={myOptions} name="About" component={About} />
</Stack.Navigator>
</NavigationContainer>
And this is my code for the market navigation:
<NavigationContainer ref={navigationRef} independent={true}>
<Stack.Navigator>
<Stack.Screen
options={myOptions}
name="Market"
component={Market}
/>
<Stack.Screen
options={myOptions}
name="Cart"
component={Cart}
/>
</Stack.Navigator>
</NavigationContainer>
I faced this when navigating to nested navigator using "screen" option like this:
navigation.navigate('Root', {
screen: 'Settings'
})
;
As mentioned in the documentation:
By default, when you navigate a screen in the nested navigator, the
specified screen is used as the initial screen and the initial route
prop on the navigator is ignored.
To solve this you should use "initial: false" like so:
navigation.navigate('Root', {
screen: 'Settings',
initial: false,
});
Could you add in the code where you navigate from Home to MarketNavigation and back?
I am using React-Navigation v 5.0.1, I have a Drawer navigator nested inside Stack navigator that looks like this:
MainStack.js
function MainStack() {
return(
<Stack.Navigator>
<Stack.Screen name="Splash" component={Splash} />
<Stack.Screen name="Login" component={Login} />
<Stack.Screen name="HomeDrawerStack" component={HomeDrawerStack} />
</Stack.Navigator>
)
}
HomeDrawerStack.js
function HomeDrawerStack() {
return (
<Drawer.Navigator>
<Drawer.Screen name="Home" component={Home} />
</Drawer.Navigator>
)
}
When I tap a logout button on Home screen, how do I navigate to Login screen and reset / clear all other screens? (so it triggers the componentWillUnmount on other screens)
This code will navigate to Login Screen after clearing the stack. so that back button or back swipe will not work to navigate to HomeDrawerStack
navigation.reset({
index: 0,
routes: [{ name: "Login" }],
});
if I share how I handled it, it is like, I am sharing my code snippet as png here, so what I have done is appended Navigator with redux, and I use to change my stack or replace my stack by dispatching event to store attached to Navigator.
