Screen API

This API is relevant when in a screen component context - it allows a screen to push other screens, pop screens, change its navigator style, etc. Access to this API is available through the navigator object that is passed to your component through props.

push(params)

Push a new screen into this screen’s navigation stack.

this.props.navigator.push({
  screen: 'example.ScreenThree', // unique ID registered with Navigation.registerScreen
  title: undefined, // navigation bar title of the pushed screen (optional)
  titleImage: require('../../img/my_image.png'), //navigation bar title image instead of the title text of the pushed screen (optional)
  passProps: {}, // Object that will be passed as props to the pushed screen (optional)
  animated: true, // does the push have transition animation or does it happen immediately (optional)
  backButtonTitle: undefined, // override the back button title (optional)
  backButtonHidden: false, // hide the back button altogether (optional)
  navigatorStyle: {}, // override the navigator style for the pushed screen (optional)
  navigatorButtons: {} // override the nav buttons for the pushed screen (optional)
});

pop(params = {})

Pop the top screen from this screen’s navigation stack.

this.props.navigator.pop({
  animated: true // does the pop have transition animation or does it happen immediately (optional)
});

popToRoot(params = {})

Pop all the screens until the root from this screen’s navigation stack.

this.props.navigator.popToRoot({
  animated: true // does the pop have transition animation or does it happen immediately (optional)
});

resetTo(params)

Reset the screen’s navigation stack to a new screen (the stack root is changed).

this.props.navigator.resetTo({
  screen: 'example.ScreenThree', // unique ID registered with Navigation.registerScreen
  title: undefined, // navigation bar title of the pushed screen (optional)
  passProps: {}, // simple serializable object that will pass as props to the pushed screen (optional)
  animated: true, // does the push have transition animation or does it happen immediately (optional)
  navigatorStyle: {}, // override the navigator style for the pushed screen (optional)
  navigatorButtons: {} // override the nav buttons for the pushed screen (optional)
});

showModal(params = {})

Show a screen as a modal.

this.props.navigator.showModal({
  screen: "example.ModalScreen", // unique ID registered with Navigation.registerScreen
  title: "Modal", // title of the screen as appears in the nav bar (optional)
  passProps: {}, // simple serializable object that will pass as props to the modal (optional)
  navigatorStyle: {}, // override the navigator style for the screen, see "Styling the navigator" below (optional)
  animationType: 'slide-up' // 'none' / 'slide-up' , appear animation for the modal (optional, default 'slide-up')
});

dismissModal(params = {})

Dismiss the current modal.

this.props.navigator.dismissModal({
  animationType: 'slide-down' // 'none' / 'slide-down' , dismiss animation for the modal (optional, default 'slide-down')
});

dismissAllModals(params = {})

Dismiss all the current modals at the same time.

this.props.navigator.dismissAllModals({
  animationType: 'slide-down' // 'none' / 'slide-down' , dismiss animation for the modal (optional, default 'slide-down')
});

showLightBox(params = {})

Show a screen as a lightbox.

this.props.navigator.showLightBox({
 screen: "example.LightBoxScreen", // unique ID registered with Navigation.registerScreen
 passProps: {}, // simple serializable object that will pass as props to the lightbox (optional)
 style: {
   backgroundBlur: "dark", // 'dark' / 'light' / 'xlight' / 'none' - the type of blur on the background
   backgroundColor: "#ff000080" // tint color for the background, you can specify alpha here (optional)
 }
});

dismissLightBox(params = {})

Dismiss the current lightbox.

this.props.navigator.dismissLightBox();

handleDeepLink(params = {})

Trigger a deep link within the app. See deep links for more details about how screens can listen for deep link events.

this.props.navigator.handleDeepLink({
  link: "chats/2349823023" // the link string (required)
});

handleDeepLink can also be called statically:

  import {Navigation} from 'react-native-navigation';
  Navigation.handleDeepLink(...);

setOnNavigatorEvent(callback)

Set a handler for navigator events (like nav button press). This would normally go in your component constructor.

// this.onNavigatorEvent will be our handler
this.props.navigator.setOnNavigatorEvent(this.onNavigatorEvent.bind(this));

setButtons(params = {})

Set buttons dynamically on the navigator. If your buttons don’t change during runtime, see “Adding buttons to the navigator” below to add them using static navigatorButtons = {...};.

this.props.navigator.setButtons({
  leftButtons: [], // see "Adding buttons to the navigator" below for format (optional)
  rightButtons: [], // see "Adding buttons to the navigator" below for format (optional)
  animated: true // does the change have transition animation or does it happen immediately (optional)
});

setTitle(params = {})

Set the nav bar title dynamically. If your title doesn’t change during runtime, set it when the screen is defined / pushed.

this.props.navigator.setTitle({
  title: "Dynamic Title" // the new title of the screen as appears in the nav bar
});

toggleDrawer(params = {})

Toggle the side menu drawer assuming you have one in your app.

this.props.navigator.toggleDrawer({
  side: 'left', // the side of the drawer since you can have two, 'left' / 'right'
  animated: true, // does the toggle have transition animation or does it happen immediately (optional)
  to: 'open' // optional, 'open' = open the drawer, 'closed' = close it, missing = the opposite of current state
});

toggleTabs(params = {})

Toggle whether the tabs are displayed or not (only in tab-based apps).

this.props.navigator.toggleTabs({
  to: 'hidden', // required, 'hidden' = hide tab bar, 'shown' = show tab bar
  animated: true // does the toggle have transition animation or does it happen immediately (optional)
});

setTabBadge(params = {})

Set the badge on a tab (any string or numeric value).

this.props.navigator.setTabBadge({
  tabIndex: 0, // (optional) if missing, the badge will be added to this screen's tab
  badge: 17 // badge value, null to remove badge
});

switchToTab(params = {})

Switch to a tab (sets it as the currently selected tab).

this.props.navigator.switchToTab({
  tabIndex: 0 // (optional) if missing, this screen's tab will become selected
});

toggleNavBar(params = {})

Toggle whether the navigation bar is displayed or not.

this.props.navigator.toggleNavBar({
  to: 'hidden', // required, 'hidden' = hide navigation bar, 'shown' = show navigation bar
  animated: true // does the toggle have transition animation or does it happen immediately (optional). By default animated: true
});

Screen Visibility

Listen to screen visibility events in onNavigatorEvent handler:

export default class ExampleScreen extends Component {
  constructor(props) {
    super(props);
    this.props.navigator.setOnNavigatorEvent(this.onNavigatorEvent.bind(this));
  }
  onNavigatorEvent(event) {
    switch(event.id) {
      case 'willAppear':
       break;
      case 'didAppear':
        break;
      case 'willDisappear':
        break;
      case 'didDisappear':
        break;
    }
  }
}
