Supporting safe areas

By default, React Navigation tries to ensure that the elements of the navigators display correctly on devices with notches (e.g. iPhone X) and UI elements which may overlap the app content. Such items include:

• Physical notches
• Status bar overlay
• Home activity indicator on iOS
• Navigation bar on Android

The area not overlapped by such items is referred to as "safe area".

We try to apply proper insets on the UI elements of the navigators to avoid being overlapped by such items. The goal is to (a) maximize usage of the screen (b) without hiding content or making it difficult to interact with by having it obscured by a physical display cutout or some operating system UI.

While React Navigation handles safe areas for the built-in UI elements by default, your own content may also need to handle it to ensure that content isn't hidden by these items.

It's tempting to solve (a) by wrapping your entire app in a container with padding that ensures all content will not be occluded. But in doing so, we waste a bunch of space on the screen, as pictured in the image on the left below. What we ideally want is the image pictured on the right.

While React Native exports a SafeAreaView component, this component only supports iOS 10+ with no support for older iOS versions or Android. In addition, it also has some issues, i.e. if a screen containing safe area is animating, it causes jumpy behavior. So we recommend to use the useSafeAreaInsets hook from the react-native-safe-area-context library to handle safe areas in a more reliable way.

warning

The react-native-safe-area-context library also exports a SafeAreaView component. While it works on Android, it also has the same issues related to jumpy behavior when animating. So we recommend always using the useSafeAreaInsets hook instead and avoid using the SafeAreaView component.

The rest of this guide gives more information on how to support safe areas in React Navigation.

Hidden/Custom Header or Tab Bar

React Navigation handles safe area in the default header. However, if you're using a custom header, it's important to ensure your UI is within the safe area.

For example, if I render nothing for the header or tabBar, nothing renders

Static

const MyTabs = createBottomTabNavigator({
  initialRouteName: 'Analytics',
  tabBar: () => null,
  screenOptions: {
    headerShown: false,
  },
  screens: {
    Analytics: Demo,
    Profile: Demo,
  },
});

const RootStack = createNativeStackNavigator({
  initialRouteName: 'Home',
  screenOptions: {
    headerShown: false,
  },
  screens: {
    Home: MyTabs,
    Settings: Demo,
  },
});

To fix this issue you can apply safe area insets on your content. This can be achieved using the useSafeAreaInsets hook from the react-native-safe-area-context library:

Static

function Demo() {
  const insets = useSafeAreaInsets();

  return (
    <View
      style={{
        flex: 1,
        justifyContent: 'space-between',
        alignItems: 'center',
        paddingTop: insets.top,
        paddingBottom: insets.bottom,
        paddingLeft: insets.left,
        paddingRight: insets.right,
      }}
    >
      <Text>This is top text.</Text>
      <Text>This is bottom text.</Text>
    </View>
  );
}

const Navigation = createStaticNavigation(RootStack);

export default function App() {
  return (
    <SafeAreaProvider>
      <Navigation />
    </SafeAreaProvider>
  );
}

Dynamic

function Demo() {
  const insets = useSafeAreaInsets();

  return (
    <View
      style={{
        flex: 1,
        justifyContent: 'space-between',
        alignItems: 'center',
        paddingTop: insets.top,
        paddingBottom: insets.bottom,
        paddingLeft: insets.left,
        paddingRight: insets.right,
      }}
    >
      <Text>This is top text.</Text>
      <Text>This is bottom text.</Text>
    </View>
  );
}
export default function App() {
  return (
    <SafeAreaProvider>
      <NavigationContainer>
        {/*(...) */}
      </NavigationContainer>
    </SafeAreaProvider>
  );
}

Make sure to wrap your app in SafeAreaProvider as per the instructions here.

This will detect if the app is running on a device with notches, if so, ensure the content isn't hidden behind any hardware elements.

Landscape Mode

Even if you're using the default navigation bar and tab bar - if your application works in landscape mode it's important to ensure your content isn't hidden behind the sensor cluster.

To fix this you can, once again, apply safe area insets to your content. This will not conflict with the navigation bar nor the tab bar's default behavior in portrait mode.

Use the hook for more control

In some cases you might need more control over which paddings are applied. For example, you can only apply the top and the bottom padding by changing the style object:

Static

import {
  SafeAreaProvider,
  useSafeAreaInsets,
} from 'react-native-safe-area-context';

function Demo() {
  const insets = useSafeAreaInsets();
  return (
    <View
      style={{
        paddingTop: insets.top,
        paddingBottom: insets.bottom,

        flex: 1,
        justifyContent: 'space-between',
        alignItems: 'center',
      }}
    >
      <Text>This is top text.</Text>
      <Text>This is bottom text.</Text>
    </View>
  );
}

const Navigation = createStaticNavigation(RootStack);

export default function App() {
  return (
    <SafeAreaProvider>
      <Navigation />
    </SafeAreaProvider>
  );
}

Try on Snack

Dynamic

import {
  SafeAreaProvider,
  useSafeAreaInsets,
} from 'react-native-safe-area-context';

function Demo() {
  const insets = useSafeAreaInsets();
  return (
    <View
      style={{
        paddingTop: insets.top,
        paddingBottom: insets.bottom,

        flex: 1,
        justifyContent: 'space-between',
        alignItems: 'center',
      }}
    >
      <Text>This is top text.</Text>
      <Text>This is bottom text.</Text>
    </View>
  );
}

Similarly, you could apply these paddings in contentContainerStyle of FlatList to have the content avoid the safe areas, but still show them under the statusbar and navigation bar when scrolling.

Summary

• Use useSafeAreaInsets hook from react-native-safe-area-context instead of SafeAreaView component
• Don't wrap your whole app in SafeAreaView, instead apply the styles to content inside your screens
• Apply only specific insets using the useSafeAreaInsets hook for more control
