I am trying to change an already develop react native application. I am new to react native. I am trying to write some Navigator
In App.js the original NavigationContained using GalioProvider. I know the traditional way to navigate to different pages but can anyone suggest me how to work with GalioProvider?
<NavigationContainer>
<GalioProvider theme={nowTheme}>
<Block flex>
<Screens />
</Block>
</GalioProvider>
</NavigationContainer>
I need to add below lines to it as well:
<Stack.Navigator>
<Stack.Screen name="Register" component={Register} />
<Stack.Screen name="Pro" component={Pro} />
</Stack.Navigator>
My final changes are like below:
<NavigationContainer>
<GalioProvider theme={nowTheme}>
<Block flex>
<Screens />
</Block>
</GalioProvider>
<Stack.Navigator>
<Stack.Screen name="Register" component={Register} />
<Stack.Screen name="Pro" component={Pro} />
</Stack.Navigator>
</NavigationContainer>
But I am getting below error:
Error: Another navigator is already registered for this container. You likely have multiple navigators under a single "NavigationContainer" or "Screen". Make sure each navigator is under a separate "Screen" container.
I have a <Tab.Navigator> and it has four <Tab.Screen> elements. What i try to do is, to press a button inside a specific <Tab.Screen> and open an another screen on top of it. But i don't want this another screen to have a <Tab.Screen> navigator in the <Tab.Navigator> bar.
I thought maybe there's an option to hide, make invisible a <Tab.Screen> but i couldn't find any documentation about it.
Is it possible to achieve this ?
According the official doc. You can reorganize your navigation and put the bottom tabs navigator inside the stack navigator like this
function HomeTabs() {
return (
<Tab.Navigator> // Here you can also navigate to both Profile and Settings
<Tab.Screen name="Home" component={Home} />
<Tab.Screen name="Feed" component={Feed} />
<Tab.Screen name="Notifications" component={Notifications} />
</Tab.Navigator>
);
}
function App() {
return (
<Stack.Navigator>
<Stack.Screen name="Home" component={HomeTabs} />
<Stack.Screen name="Profile" component={Profile} /> // Here you won't have any tabs
<Stack.Screen name="Settings" component={Settings} /> // Here neither
</Stack.Navigator>
);
}
You have to nest navigators with the stack navigator as the outer navigator and the tab navigator as the inner navigator:
https://reactnavigation.org/docs/nesting-navigators
You have to reorganize your navigation structure , as documentation describe https://reactnavigation.org/docs/hiding-tabbar-in-screens
Let's say we have 5 screens: Home, Feed, Notifications, Profile and Settings, and your navigation structure looks like this:
function HomeStack() {
return (
<Stack.Navigator>
<Stack.Screen name="Home" component={Home} />
<Stack.Screen name="Profile" component={Profile} />
<Stack.Screen name="Settings" component={Settings} />
</Stack.Navigator>
);
}
function App() {
return (
<Tab.Navigator>
<Tab.Screen name="Home" component={HomeStack} />
<Tab.Screen name="Feed" component={Feed} />
<Tab.Screen name="Notifications" component={Notifications} />
</Tab.Navigator>
);
}
With this structure, when we navigate to the Profile or Settings screen, the tab bar will still stay visible over those screens.
But if we want to show the tab bar only on the Home, Feed and Notifications screens, but not on the Profile and Settings screens, we'll need to change the navigation structure. The easiest way to achieve this is to nest the tab navigator inside the first screen of the stack instead of nesting stack inside tab navigator:
function HomeTabs() {
return (
<Tab.Navigator>
<Tab.Screen name="Home" component={Home} />
<Tab.Screen name="Feed" component={Feed} />
<Tab.Screen name="Notifications" component={Notifications} />
</Tab.Navigator>
);
}
function App() {
return (
<Stack.Navigator>
<Stack.Screen name="Home" component={HomeTabs} />
<Stack.Screen name="Profile" component={Profile} />
<Stack.Screen name="Settings" component={Settings} />
</Stack.Navigator>
);
}
After re-organizing the navigation structure, now if we navigate to the Profile or Settings screens, the tab bar won't be visible over the screen anymore.
I am currently building my first app using react-native and i am struggeling with the right structure for nested navigation using react-native-navigation .
My app should be navigatable using a Tab-bar. On every screen of that Tab-bar I might need to have a Stack navigation available.
App.js:
<NavigatonContainer>
<BottomTab.Navigator>
<BottomTab.Screen name="Screen1" component={Screen1}/>
<BottomTab.Screen name="Screen2" component={Screen2}/>
<BottomTab.Screen name="Screen3" component={Screen3}/>
<BottomTab.Navigator/>
<NavigationContainer/>
Now if i want to use a Stack navigation inside Screen1, what would be the best approach? My approach would be to move all content that should be display when the first Tab is active to a new screen called "Screen1Start" and then having following code on "Screen1".
Screen1.js:
<Stack.Navigator>
<Stack.Screen name="Screen1Start" component={Screen1Start}/>
<Stack.Screen name="Screen1Settings" component={Screen1Settings}/>
<Stack.Screen name="Screen1Details" component={Screen1Details}/>
</Stack.Navigator>
Is that the right thing to do? Are there better approaches to this? Thanks for your help!
You can have a stack inside of a stack and then navigate to each individually with navigation.navigate('name'). In the react navigation docs you can read more about navigating inside nested navigators here.
Pretty quick example would be:
function Home() {
return (
<Tab.Navigator>
<Tab.Screen name="Feed" component={Feed} />
<Tab.Screen name="Messages" component={Messages} />
</Tab.Navigator>
);
}
function App() {
return (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen
name="Home"
component={Home}
options={{ headerShown: false }}
/>
<Stack.Screen name="Profile" component={Profile} />
<Stack.Screen name="Settings" component={Settings} />
</Stack.Navigator>
</NavigationContainer>
);
}
Here you can see that Home is a stack of feed and messages and then you have individual screens for Profile and Settings. Like so you can have another stack instead of Profile or Settings binded by another navigator such as toptab or bottomtab.
The react navigation docs explain this very detailed and easy to understand. I would recommend you to read from start to finish so you have a deeper understanding of the navigation.
I am new in React Native and I want to create stack navigation based on modules like
Auth
Login
Register
Forgot
Home
Home
Dashboard
Tabs
Profile
1 - Auth stack have only above routes access where user can only navigate
2 - Home stack have only above routes access where user can navigate around home stack
Please guide here or any sample existing
This is explained with examples in react navigation authentication flows guide.
Here's simple example based on your routes -
isSignedIn ? (
<>
<Stack.Screen name="Dashboard" component={DashboardScreen} />
<Stack.Screen name="Tabs" component={TabsScreen} />
<Stack.Screen name="Profile" component={ProfileScreen} />
</>
) : (
<>
<Stack.Screen name="Login" component={LoginScreen} />
<Stack.Screen name="Register" component={RegisterScreen} />
<Stack.Screen name="Forgot" component={ForgotScreen} />
<Stack.Screen name="Home" component={HomeScreen} />
</>
);
I'm using React Native BottomTabNavigator.
Example:
<Tab.Navigator tabBarOptions={tabBarOptions} screenOptions={screenOptions}>
<Tab.Screen name="Home" component={Home} />
<Tab.Screen name="Saved" component={Saved} />
<Tab.Screen name="Map" component={Map} />
<Tab.Screen name="Profile" component={Profile} />
</Tab.Navigator>
I want to make the last tab focused instead of the first.
I can't find any option in the documentation.
It should be something like options={{ focused: true }}
Or maybe it's not implemented at all
<Tab.Navigator initialRouteName={"Your Initial Screen Name"}
...>
</Tab.Navigator>
