Navigation prop reference

Each screen component in your app is provided with the navigation prop automatically. The prop contains various convenience functions that dispatch navigation actions. It looks like this:

• navigation
• navigate - go to another screen, figures out the action it needs to take to do it
• reset - wipe the navigator state and replace it with a new route
• goBack - close active screen and move back in the stack
• setParams - make changes to route's params
• dispatch - send an action object to update the navigation state
• setOptions - update the screen's options
• isFocused - check whether the screen is focused
• addListener - subscribe to updates to events from the navigators

It's important to highlight the navigation prop is not passed in to all components; only screen components receive this prop automatically! React Navigation doesn't do any magic here. For example, if you were to define a MyBackButton component and render it as a child of a screen component, you would not be able to access the navigation prop on it. If, however, you wish to access the navigation prop in any of your components, you may use the useNavigation hook.

setParams/setOptions etc. should only be called in useEffect/useLayoutEffect/componentDidMount/componentDidUpdate etc. Not during render or in constructor.

Navigator-dependent functions¶

There are several additional functions present on navigation prop based on the kind of the current navigator.

If the navigator is a stack navigator, several alternatives to navigate and goBack are provided and you can use whichever you prefer. The functions are:

• navigation
• replace - replace the current screen with a new one
• push - push a new screen onto the stack
• pop - go back in the stack
• popToTop - go to the top of the stack

See Stack navigator helpers and Native Stack navigator helpers for more details on these methods.

If the navigator is a tab navigator, the following are also available:

• navigation
• jumpTo - go to a specific screen in the tab navigator

See Bottom Tab navigator helpers, Material Top Tab navigator helpers and Material Bottom Tab navigator helpers for more details on these methods.

If the navigator is a drawer navigator, the following are also available:

• navigation
• jumpTo - go to a specific screen in the drawer navigator
• openDrawer - open the drawer
• closeDrawer - close the drawer
• toggleDrawer - toggle the state, ie. switch from closed to open and vice versa

See Drawer navigator helpers for more details on these methods.

Common API reference¶

The vast majority of your interactions with the navigation prop will involve navigate, goBack, and setParams.

navigate¶

The navigate method lets us navigate to another screen in your app. It takes the following arguments:

navigation.navigate(name, params)

• name - A destination name of the route that has been defined somewhere
• params - Params to pass to the destination route.

function HomeScreen({ navigation: { navigate } }) {
  return (
    <View>
      <Text>This is the home screen of the app</Text>
      <Button
        onPress={() =>
          navigate('Profile', { names: ['Brent', 'Satya', 'Michaś'] })
        }
        title="Go to Brent's profile"
      />
    </View>
  );
}

In a native stack navigator, calling navigate with a screen name will result in different behavior based on if the screen is already present or not. If the screen is already present in the stack's history, it'll go back to that screen and remove any screens after that. If the screen is not present, it'll push a new screen.

For example, if you have a stack with the history Home > Profile > Settings and you call navigate(Profile), the resulting screens will be Home > Profile as it goes back to Profile and removes the Settings screen.

By default, the screen is identified by its name. But you can also customize it to take the params into account by using the getId prop.

For example, say you have specified a getId prop for Profile screen:

1

<Tab.Screen name={Profile} component={ProfileScreen} getId={({ params }) => params.userId} />

Now, if you have a stack with the history Home > Profile (userId: bob) > Settings and you call navigate(Profile, { userId: 'alice' }), the resulting screens will be Home > Profile (userId: bob) > Settings > Profile (userId: alice) since it'll add a new Profile screen as no matching screen was found.

goBack¶

The goBack method lets us go back to the previous screen in the navigator.

By default, goBack will go back from the screen that it is called from:

1
2
3
4
5
6
7

function ProfileScreen({ navigation: { goBack } }) {
  return (
    <View>
      <Button onPress={() => goBack()} title="Go back from ProfileScreen" />
    </View>
  );
}

Going back from a specific screen¶

Consider the following navigation stack history:

1
2
3
4

navigation.navigate({ name: SCREEN, key: SCREEN_KEY_A });
navigation.navigate({ name: SCREEN, key: SCREEN_KEY_B });
navigation.navigate({ name: SCREEN, key: SCREEN_KEY_C });
navigation.navigate({ name: SCREEN, key: SCREEN_KEY_D });

Now you are on screen D and want to go back to screen A (popping D, C, and B). Then you can use navigate:

1

navigation.navigate({ key: SCREEN_KEY_A }); // will go to screen A FROM screen D

Alternatively, as screen A is the top of the stack, you can use navigation.popToTop().

reset¶

The reset method lets us replace the navigator state with a new state:

1
2
3
4

navigation.reset({
  index: 0,
  routes: [{ name: 'Profile' }],
});

The state object specified in reset replaces the existing navigation state with the new one, i.e. removes existing screens and add new ones. If you want to preserve the existing screens when changing the state, you can use CommonActions.reset with dispatch instead.

Note: Consider the navigator's state object to be internal and subject to change in a minor release. Avoid using properties from the navigation state object except index and routes, unless you really need it. If there is some functionality you cannot achieve without relying on the structure of the state object, please open an issue.

setParams¶

The setParams method lets us update the params (route.params) of the current screen. setParams works like React's setState - it shallow merges the provided params object with the current params.

function ProfileScreen({ navigation: { setParams } }) {
  return (
    <Button
      onPress={() =>
        setParams({
          friends:
            route.params.friends[0] === 'Brent'
              ? ['Wojciech', 'Szymon', 'Jakub']
              : ['Brent', 'Satya', 'Michaś'],
          title:
            route.params.title === "Brent's Profile"
              ? "Lucy's Profile"
              : "Brent's Profile",
        })
      }
      title="Swap title and friends"
    />
  );
}

setOptions¶

The setOptions method lets us set screen options from within the component. This is useful if we need to use the component's props, state or context to configure our screen.

function ProfileScreen({ navigation, route }) {
  const [value, onChangeText] = React.useState(route.params.title);

  React.useEffect(() => {
    navigation.setOptions({
      title: value === '' ? 'No title' : value,
    });
  }, [navigation, value]);

  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <TextInput
        style={{ height: 40, borderColor: 'gray', borderWidth: 1 }}
        onChangeText={onChangeText}
        value={value}
      />
      <Button title="Go back" onPress={() => navigation.goBack()} />
    </View>
  );
}

Any options specified here are shallow merged with the options specified when defining the screen.

When using navigation.setOptions, we recommend specifying a placeholder in the screen's options prop and update it using navigation.setOptions. This makes sure that the delay for updating the options isn't noticeable to the user. It also makes it work with lazy-loaded screens.

You can also use React.useLayoutEffect to reduce the delay in updating the options. But we recommend against doing it if you support web and do server side rendering.

Note: navigation.setOptions is intended to provide the ability to update existing options when necessary. It's not a replacement for the options prop on the screen. Make sure to use navigation.setOptions sparingly only when absolutely necessary.

Navigation events¶

Screens can add listeners on the navigation prop with the addListener method. For example, to listen to the focus event:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

function Profile({ navigation }) {
  React.useEffect(() => {
    const unsubscribe = navigation.addListener('focus', () => {
      // do something
    });

    return unsubscribe;
  }, [navigation]);

  return <ProfileContent />;
}

See Navigation events for more details on the available events and the API usage.

isFocused¶

This method lets us check whether the screen is currently focused. Returns true if the screen is focused and false otherwise.

1

const isFocused = navigation.isFocused();

This method doesn't re-render the screen when the value changes and mainly useful in callbacks. You probably want to use useIsFocused instead of using this directly, it will return a boolean a prop to indicating if the screen is focused.

Advanced API Reference¶

The dispatch function is much less commonly used, but a good escape hatch if you can't do what you need with the available methods such as navigate, goBack etc. We recommend to avoid using the dispatch method often unless absolutely necessary.

dispatch¶

The dispatch method lets us send a navigation action object which determines how the navigation state will be updated. All of the navigation functions like navigate use dispatch behind the scenes.

Note that if you want to dispatch actions you should use the action creators provided in this library instead of writing the action object directly.

See Navigation Actions Docs for a full list of available actions.

1
2

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

navigation.dispatch(
  CommonActions.navigate({
    name: 'Profile',
    params: {},
  })
);

When dispatching action objects, you can also specify few additional properties:

• source - The key of the route which should be considered as the source of the action. For example, the replace action will replace the route with the given key. By default, it'll use the key of the route that dispatched the action. You can explicitly pass undefined to override this behavior.
• target - The key of the navigation state the action should be applied on. By default, actions bubble to other navigators if not handled by a navigator. If target is specified, the action won't bubble if the navigator with the same key didn't handle it.

Example:

1
2
3
4
5
6
7

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

navigation.dispatch({
  ...CommonActions.navigate('Profile'),
  source: 'someRoutekey',
  target: 'someStatekey',
});

Custom action creators¶

It's also possible to pass a action creator function to dispatch. The function will receive the current state and needs to return a navigation action object to use:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12

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

navigation.dispatch((state) => {
  // Add the home route to the start of the stack
  const routes = [{ name: 'Home' }, ...state.routes];

  return CommonActions.reset({
    ...state,
    routes,
    index: routes.length - 1,
  });
});

You can use this functionality to build your own helpers that you can utilize in your app. Here is an example which implements inserting a screen just before the last one:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

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

const insertBeforeLast = (routeName, params) => (state) => {
  const routes = [
    ...state.routes.slice(0, -1),
    { name: routeName, params },
    state.routes[state.routes.length - 1],
  ];

  return CommonActions.reset({
    ...state,
    routes,
    index: routes.length - 1,
  });
};

Then use it like:

1

navigation.dispatch(insertBeforeLast('Home'));

canGoBack¶

This method returns a boolean indicating whether there's any navigation history available in the current navigator, or in any parent navigators. You can use this to check if you can call navigation.goBack():

1
2
3

if (navigation.canGoBack()) {
  navigation.goBack();
}

Don't use this method for rendering content as this will not trigger a re-render. This is only intended for use inside callbacks, event listeners etc.

getParent¶

This method returns the navigation prop from the parent navigator that the current navigator is nested in. For example, if you have a stack navigator and a tab navigator nested inside the stack, then you can use getParent inside a screen of the tab navigator to get the navigation prop passed from the stack navigator.

It accepts an optional ID parameter to refer to a specific parent navigator. For example, if your screen is nested with multiple levels of nesting somewhere under a drawer navigator with the id prop as "LeftDrawer", you can directly refer to it without calling getParent multiple times.

To use an ID for a navigator, first pass a unique id prop:

1
2
3

<Drawer.Navigator id="LeftDrawer">
  {/* .. */}
</Drawer.Navigator>

Then when using getParent, instead of:

1
2
3
4
5
6

// Avoid this
const drawerNavigation = navigation.getParent().getParent();

// ...

drawerNavigation?.openDrawer();

You can do:

1
2
3
4
5
6

// Do this
const drawerNavigation = navigation.getParent('LeftDrawer');

// ...

drawerNavigation?.openDrawer();

This approach allows components to not have to know the nesting structure of the navigators. So it's highly recommended that use an id when using getParent.

This method will return undefined if there is no matching parent navigator. Be sure to always check for undefined when using this method.

getState¶

Note: Consider the navigator's state object to be internal and subject to change in a minor release. Avoid using properties from the navigation state object except index and routes, unless you really need it. If there is some functionality you cannot achieve without relying on the structure of the state object, please open an issue.

This method returns the state object of the navigator which contains the screen. Getting the navigator state could be useful in very rare situations. You most likely don't need to use this method. If you do, make sure you have a good reason.

If you need the state for rendering content, you should use useNavigationState instead of this method.
