Elements Library

A component library containing the UI elements and helpers used in React Navigation. It can be useful if you're building your own navigator, or want to reuse a default functionality in your app.

Installation​

To use this package, ensure that you have @react-navigation/native and its dependencies (follow this guide), then install @react-navigation/elements:

npm install @react-navigation/elements@next

Components​

A component that can be used as a header. This is used by all the navigators by default.

Usage:

import { Header } from '@react-navigation/elements';

function MyHeader() {
  return <Header title="My app" />;
}
Try on Snack

To use the header in a navigator, you can use the header option in the screen options:

import { Header, getHeaderTitle } from '@react-navigation/elements';

const MyStack = createNativeStackNavigator({
  screenOptions: {
    header: ({ options, route }) => (
      <Header {...options} title={getHeaderTitle(options, route.name)} />
    ),
  },
  screens: {
    Home: HomeScreen,
  },
});
Try on Snack
note

This doesn't replicate the behavior of the header in stack and native stack navigators as the stack navigator also includes animations, and the native stack navigator header is provided by the native platform.

It accepts the following props:

headerTitle​

String or a function that returns a React Element to be used by the header. Defaults to scene title.

When a function is specified, it receives an object containing following properties:

  • allowFontScaling: Whether it scale to respect Text Size accessibility settings.
  • tintColor: Text color of the header title.
  • style: Style object for the Text component.
  • children: The title string (from title in options).
const RootStack = createNativeStackNavigator({
  screens: {
    Home: {
      screen: HomeScreen,
      options: {
        headerTitle: ({ allowFontScaling, tintColor, style, children }) => (
          <Text
            style={[style, { color: tintColor }]}
            allowFontScaling={allowFontScaling}
          >
            {children}
          </Text>
        ),
      },
    },
  },
});

headerTitleAlign​

How to align the header title. Possible values:

  • left
  • center

Defaults to center on iOS and left on Android.

headerTitleAllowFontScaling​

Whether header title font should scale to respect Text Size accessibility settings. Defaults to false.

headerLeft​

Function which returns a React Element to display on the left side of the header.

It receives an object containing following properties:

  • tintColor: The color of the icon and label.
  • pressColor: The color of the material ripple (Android >= 5.0 only).
  • pressOpacity: The opacity of the button when it's pressed (Android < 5.0, and iOS).
  • labelVisible: Whether the label text is visible. Defaults to true on iOS and false on Android.
  • href: The URL to open when the button is pressed on the Web.

You can use it to implement your custom left button, for example:

const RootStack = createNativeStackNavigator({
  screens: {
    Home: {
      screen: HomeScreen,
      options: {
        headerLeft: (props) => (
          <MyButton {...props} onPress={() => {
            // Do something
          }}>
        )
      }
    }
  }
})

headerRight​

Function which returns a React Element to display on the right side of the header.

It receives an object containing following properties:

  • tintColor: The color of the icon and label.
  • pressColor: The color of the material ripple (Android >= 5.0 only).
  • pressOpacity: The opacity of the button when it's pressed (Android < 5.0, and iOS).
const RootStack = createNativeStackNavigator({
  screens: {
    Home: {
      screen: HomeScreen,
      options: {
        headerLeft: (props) => (
          <MyButton {...props} onPress={() => {
            // Do something
          }}>
        )
      }
    }
  }
})

headerShadowVisible​

Whether to hide the elevation shadow (Android) or the bottom border (iOS) on the header.

This is a short-hand for the following styles:

{
  elevation: 0,
  shadowOpacity: 0,
  borderBottomWidth: 0,
}

If the above styles are specified in headerStyle along with headerShadowVisible: false, then headerShadowVisible: false will take precedence.

headerStyle​

Style object for the header. You can specify a custom background color here, for example.

headerTitleStyle​

Style object for the title component

headerLeftContainerStyle​

Customize the style for the container of the headerLeft component, for example to add padding.

headerRightContainerStyle​

Customize the style for the container of the headerRight component, for example to add padding.

headerTitleContainerStyle​

Customize the style for the container of the headerTitle component, for example to add padding.

By default, headerTitleContainerStyle is with an absolute position style and offsets both left and right. This may lead to white space or overlap between headerLeft and headerTitle if a customized headerLeft is used. It can be solved by adjusting left and right style in headerTitleContainerStyle and marginHorizontal in headerTitleStyle.

headerBackgroundContainerStyle​

Style object for the container of the headerBackground element.

headerTintColor​

Tint color for the header

headerPressColor​

Color for material ripple (Android >= 5.0 only)

headerPressOpacity​

Press opacity for the buttons in header (Android < 5.0, and iOS)

headerTransparent​

Defaults to false. If true, the header will not have a background unless you explicitly provide it with headerBackground. The header will also float over the screen so that it overlaps the content underneath.

This is useful if you want to render a semi-transparent header or a blurred background.

Note that if you don't want your content to appear under the header, you need to manually add a top margin to your content. React Navigation won't do it automatically.

To get the height of the header, you can use HeaderHeightContext with React's Context API or useHeaderHeight.

headerBackground​

Function which returns a React Element to render as the background of the header. This is useful for using backgrounds such as an image or a gradient.

For example, you can use this with headerTransparent to render a blur view to create a translucent header.

const Stack = createStackNavigator({
  initialRouteName: 'Home',
  screens: {
    Home: {
      screen: HomeScreen,
      options: {
        headerTransparent: true,
        headerBackground: () => (
          <BlurView
            tint="dark"
            intensity={100}
            style={StyleSheet.absoluteFill}
          />
        ),
      },
    },
    Profile: ProfileScreen,
  },
});
Try on Snack

headerStatusBarHeight​

Extra padding to add at the top of header to account for translucent status bar. By default, it uses the top value from the safe area insets of the device. Pass 0 or a custom value to disable the default behavior, and customize the height.

HeaderBackground​

A component containing the styles used in the background of the header, such as the background color and shadow. It's the default for headerBackground. It accepts the same props as a View.

Usage:

<HeaderBackground style={{ backgroundColor: 'tomato' }} />

HeaderTitle​

A component used to show the title text in header. It's the default for headerTitle. It accepts the same props as a Text.

The color of title defaults to the theme text color. You can override it by passing a tintColor prop.

Usage:

<HeaderTitle>Hello</HeaderTitle>

HeaderButton​

A component used to show a button in header. It can be used for both left and right buttons. It accepts the following props:

  • onPress - Callback to call when the button is pressed.
  • href - The href to use for the anchor tag on web.
  • disabled - Boolean which controls whether the button is disabled.
  • accessibilityLabel - Accessibility label for the button for screen readers.
  • testID - ID to locate this button in tests.
  • tintColor - Tint color for the header button.
  • pressColor - Color for material ripple (Android >= 5.0 only).
  • pressOpacity - Opacity when the button is pressed if material ripple isn't supported by the platform.

    name="dots-horizontal-circle-outline"
    size={24}
    color={tintColor}
  />
</HeaderButton>

HeaderBackButton​

A component used to show the back button header. It's the default for headerLeft in the stack navigator. It accepts the following props:

  • disabled - Boolean which controls Whether the button is disabled.
  • onPress - Callback to call when the button is pressed.
  • pressColor - Color for material ripple (Android >= 5.0 only).
  • backImage - Function which returns a React Element to display custom image in header's back button.
  • tintColor - Tint color for the header.
  • label - Label text for the button. Usually the title of the previous screen. By default, this is only shown on iOS.
