如何在反应导航中获取当前路径名称？

While using "react-navigation": "^3.0.8" and DrawerNavigator it can be accessed from the this.props object using this.props.activeItemKey

You can catch it as the following code:

this.props.navigation.state.routeName

If you are using nested navigators, you can use this code to get current active screen's state

import { NavigationState } from 'react-navigation';


const getActiveRouteState = function (route: NavigationState): NavigationState {
if (!route.routes || route.routes.length === 0 || route.index >= route.routes.length) {
return route;
}


const childActiveRoute = route.routes[route.index] as NavigationState;
return getActiveRouteState(childActiveRoute);
}

Usage:

const activeRoute = getActiveRouteState(this.props.navigation.state);

I'm using this when I need to get current active screen's state from NavigationDrawer.

I have multiple TabNavigators nested in a BottomTabNavigator. I get the current route of the TabNavigator with:

    const pathAndParams = props.navigation.router.getPathAndParamsForState(props.navigation.state) || {}
const activePath = pathAndParams.path

Preparation

register 🔗NavigationService.js,see the doc detail in Navigating without the navigation prop

<App
ref={navigatorRef => {
NavigationService.setTopLevelNavigator(navigatorRef);
}}
/>

recursion function

function getCurrentRoute(nav){
if(Array.isArray(nav.routes)&&nav.routes.length>0){
return getCurrentRoute(nav.routes[nav.index])
}else {
return nav.routeName
}
}

get current routeName

getCurrentRoute(NavigationService.getNavigator().state.nav)

For react-navigation v5, you could use the useNavigationState hook -

import {useNavigationState} from '@react-navigation/native';


const state = useNavigationState(state => state);
const routeName = (state.routeNames[state.index]);
console.log(routeName);

For react-navigation v5:

import { useRoute } from '@react-navigation/native';


const route = useRoute();
console.log(route.name);

This works fine in react-navigation v5.x

this.props.route.name

In React Navigation v5, I was able to pull the current route name with the below approach:

import { useNavigationState } from '@react-navigation/native'


const routes = useNavigationState(state => state.routes)
const currentRoute = routes[routes.length -1].name
console.log('currentRoute: ',currentRoute)

const routeNameRef = React.createRef();


<NavigationContainer
ref={navigationRef}
onReady={() => routeNameRef.current = navigationRef.current.getCurrentRoute().name}
onStateChange={() => {
const previousRouteName = routeNameRef.current
const currentRouteName = navigationRef.current.getCurrentRoute().name


if (previousRouteName !== currentRouteName) {
// Do something here with it
}


// Save the current route name for later comparision
routeNameRef.current = currentRouteName
}}
>
{/* ... */}
</NavigationContainer>
);


export function getCurrentRouteName(action) {
return routeNameRef;
}

You can import the function getCurrentRouteName and use this to get the current route name and its working in any nested navigators in React Navigation 5.

this.props.navigation.state.routeName works only in react-navigation 4 but react-navigation 5 doesn't support it.

The current route name can be achieved by using redux:

-Navigator component passes route object as a prop to the child component

-The Child component receives props and could find the route name in route.name

-To get updated route name on the screen change you can use focus event listener on navigation

<====== Parent Component where navigation is implemented ======>

import React from "react";
import { createMaterialTopTabNavigator } from "@react-navigation/material-top-
tabs";


import ChildScreen from "../screens/Home/childScreen";


const Tab = createMaterialTopTabNavigator();


const ParentNavigations = () => {


return (


<Tab.Navigator
>
<Tab.Screen name="ChildScreen" component={ChildScreen} />
</Tab.Navigator>
);
};


export default ParentNavigations;

<===== Child component =====>

import React, { useEffect } from "react";
import { View, StyleSheet } from "react-native";
import { useDispatch } from "react-redux";
import ActionTypes from "../../store/actions/ActionsTypes";


const ChildScreen = ({ navigation, route }) => {
const dispatch = useDispatch();
useEffect(() => {
const unsubscribe = navigation.addListener("focus", () => {
dispatch({ type: ActionTypes.SETROUTE, payload: route.name }); // every time when screen gets focued it will update the route through redux
});
return unsubscribe;
}, [navigation, route]);
return (
<View style={styles.container}>
<Text>Hello</Text>
</View>
);
};


const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: "#0C0B0B",
},
});


export default ChildScreen;

If you just want to see if the current screen is focused, you can use navigation.isFocused(). https://reactnavigation.org/docs/navigation-prop/#isfocused

Example:

_backAction() {
const { navigation } = this.props;
if (navigation.isFocused()) {
this.setState({
isLeavingApp: true,
});
}
}

This worked for me (I did it inside my navigation drawer)!

const getCurrentRoute = nav => {
if (Array.isArray(nav.routes) && nav.routes.length > 0) {
return getCurrentRoute(nav.routes[nav.index]);
} else {
return nav.routeName;
}
};


const currentNavigation = getCurrentRoute(this.props.navigation.state);

With version 5.x the best way currently is getFocusedRouteNameFromRoute

import { getFocusedRouteNameFromRoute } from '@react-navigation/native';


export default function Stack(route) {
// If the focused route is not found, we need to assume it's the initial screen
// This can happen during if there hasn't been any navigation inside the screen
// In our case, it's "Feed" as that's the first screen inside the navigator
const routeName = getFocusedRouteNameFromRoute(route) ?? 'Feed';
return <> ..... </>
}

import { useNavigation } from '@react-navigation/native';


const App = () => {
const navigation = useNavigation();
const { dangerouslyGetState } = useNavigation();
const { index, routes } = dangerouslyGetState()
console.log(routes[index].name);


return(
<>
</>
)
};

this worked for me try this..

const getCurrentRouteName = () => {
let _index = props.state.index;
let _routeName = props.state.routeNames;
return  _routeName[_index]
}

For 'wix/react-native-navigation' below is my working solution,

import { Navigation } from 'react-native-navigation';


// Create a variable and set the value from navigation events
let navComponent = null
Navigation.events().registerComponentDidAppearListener(event => navComponent = event)


// navComponent will have the following structure
{"componentId": "Component9", "componentName": "HomeScreen", "componentType": "Component", "passProps": {}}

It is possible to get this from the navigationRef attached to the navigation container. Where navigationRef is a ref.

export const navigationRef = React.createRef()

<NavigationContainer
ref={navigationRef}
>
<Navigator />
</NavigationContainer>

Then use: const currentRouteName = navigationRef.current.getCurrentRoute().name

Alternatively in a functional component you can useRef const navigationRef = React.useRef()

const Home = ({ navigation, route }) => {
// you will see screen key, name and params
console.log("ROUTE", route);
// rest of your code
};

You can use this in hooks as well.

console.log(navigation.dangerouslyGetState());

For react native navigation 5.x use :

props.state.routeNames[props.state.index]

This is step by step procedure of what Justin.Mathew has described in his answer.

Create a new file called RootNavigation.js and put the below content inside.

// RootNavigation.js


import * as React from 'react';


export const navigationRef = React.createRef(); // we will access all navigation props by importing this in any of the component

Now import the navigationRef from the RootNavigation.js file, and assign NavigationContainer ref to this. After this step navigationRef can function as navigation prop globally.

// App.js


import { NavigationContainer } from '@react-navigation/native';
import { navigationRef } from './RootNavigation';


export default function App() {
  

handleNavigationRef = (ref) => {
// DON'T DO navigationRef = ref, cause this will give you "navigationRef is
// read only" error.
navigationRef.current = ref;
}
return (
<NavigationContainer ref={handleNavigationRef}>
{/* ... */}
</NavigationContainer>
);
}

USAGE

Now you can import navigationRef in any of the file, even nested ones. And can use this to get the currentRoute and screen details.

//SomeNestedComonent.js


import { navigationRef } from "path/to/RootNavigation.js";


const route = navigationRef.current?.getCurrentRoute(); //current route object
const currentScreen = route.name; // current screen name

In my case, I needed to get the bottom nav index as well, this was my method

import {useNavigationState} from '@react-navigation/native';

then

const routes = useNavigationState(state => state.routes);


let place = routes[routes.length - 1];


if (place.name === 'YOUR_BOTTOM_NAV_NAME') {
if (place.state.index === 0) {
//you are in the main screen(BOTTOM_NAV : index 0)
} else {
//else navigate to index 0 screen
navigation.navigate('FirstScreen');
}
} else if (place.name === 'Another_Screen') {
navigation.navigate('navigate_to_the_place_you_want');
} else {
//otherwise come to the first screen
navigation.navigate('FirstScreen');
}

In one line with useNavigationState Hook:

const screenName = useNavigationState((state) => state.routes[state.index].name)

Try this,

const appNavigation = useNavigation();
const currentRoute = appNavigation.getCurrentRoute();

This worked for me. Navigation, and its state received as props were unreliable(at least for drawer navigator at root). So I went with this one, which seems to be giving the global navigation state.

Had to use the navigation prop being received in drawer for drawer specific functions like closeDrawer or openDrawer.

export function AppDrawer(props) {


// for closeDrawer, openDrawer etc.
const { navigation: drawerNavigation } = props;


// for referencing current route
const appNavigation = useNavigation();
const currentRoute = appNavigation.getCurrentRoute();


// ... rest of the code
}

Reference for both the variable in console -

If you are using React Navigation v6 you can use this:

import { useRoute } from '@react-navigation/native';
...
const route = useRoute();


console.log('Current Route: ', route.name);

And if you want to get the name of the screen that you are, and you are inside a nested navigator, you can do this:

import { useNavigationState } from '@react-navigation/native';
...
const routes = useNavigationState(state => state.routes);


const currentRouteIndex =
routes?.length && routes[routes.length - 1].state?.index;
const currentRoute =
routes[routes.length - 1].state?.routeNames[currentRouteIndex];


console.log('Current Route: ', currentRoute);

If you are using reach navigation version 6 you can retrieve screen name by

props.route.name

Using version: "@react-navigation/native": "^6.0.8" and this.props.navigation, I did it like this:

    let navegState = this.props.navigation.getState();
if (!!navegState)
console.log('CURRENT SCREEN', navegState.routes[navegState.index].name);

Just use navegState.routes[navegState.index] if you want the whole object

  import {getFocusedRouteNameFromRoute,useRoute} from '@react-navigation/native';


//...
const route = useRoute();
const routeName = getFocusedRouteNameFromRoute(route); // Get Nested Route Name

This simple code worked for me. Just add this function to your Util.ts/js file and from your component pass the navigation as the object.

export const getCurrentScreenName = (navigation: any) => {
return navigation.getState().routes[navigation.getState().index].name;
};

We have a lot of answer here but it is hard to apply the fix because navigation is NULL.

WHY?

• Scenario 1: We are using hooks function like: useRoute, useNavigationState,... but the navigation don't be mounted yet. So it is null and get the Error.

• Scenario 2: We are using navigation object in the current screen like HomeScreen

  const Home = ({ navigation, route }) => {
  console.log("ROUTE", route);
  // rest of your code
  };
  

but navigation is NULL in Root app with presence of NavigationContainer

Make sure to checking navigation is not NULL by using onReady() method of React navigation.

const navigationRef = useRef();
const [routeName, setRouteName] = useState('');
return (
<NavigationContainer
ref={navigationRef}
onReady={() => {
const currentRoute = navigationRef.current.getCurrentRoute();
setRouteName(currentRoute.name);
// Do whatever you want with navigation here!.
}}>
...
</NavigationContainer>);
