NavigationActions reference

All NavigationActions return an object that can be sent to the router using navigation.dispatch() method.

Note that if you want to dispatch react-navigation actions you should use the action creators provided in this library.

The following actions are supported:

• Navigate - Navigate to another route
• Back - Go back to previous state
• Set Params - Set Params for given route
• Init - Used to initialize first state if state is undefined

For actions specific to a StackNavigator, see StackActions.

The action creator functions define toString() to return the action type, which enables easy usage with third-party Redux libraries, including redux-actions and redux-saga.

navigate

The navigate action will update the current state with the result of a navigate action.

• routeName - String - Required - A destination routeName that has been registered somewhere in the app's router
• params - Object - Optional - Params to merge into the destination route
• action - Object - Optional - (advanced) The sub-action to run in the child router, if the screen is a navigator. Any one of the actions described in this doc can be set as a sub-action.
• key - String - Optional - The identifier for the route to navigate to. Navigate back to this route if it already exists

import { NavigationActions } from 'react-navigation';

const navigateAction = NavigationActions.navigate({

routeName: 'Profile',

params: {},

action: NavigationActions.navigate({ routeName: 'SubProfileRoute' }),

});

this.props.navigation.dispatch(navigateAction);

back

Go back to previous screen and close current screen. back action creator takes in one optional parameter:

• key - string or null - optional - If set, navigation will go back from the given key. If null, navigation will go back anywhere.

import { NavigationActions } from 'react-navigation';

const backAction = NavigationActions.back({

key: 'Profile',

});

this.props.navigation.dispatch(backAction);

setParams

When dispatching setParams, the router will produce a new state that has changed the params of a particular route, as identified by the key

• params - object - required - New params to be merged into existing route params
• key - string - required - Route key that should get the new params

import { NavigationActions } from 'react-navigation';

const setParamsAction = NavigationActions.setParams({

params: { title: 'Hello' },

key: 'screen-123',

});

this.props.navigation.dispatch(setParamsAction);
