target 'YourProjectTarget' do

+   pod 'react-native-safe-area', path: '../node_modules/react-native-safe-area'

end

If you received error jest-haste-map: Haste module naming collision: Duplicate module name: react-native, add lines below to your Podfile and reinstall pods.

target 'YourProjectTarget' do

+   rn_path = '../node_modules/react-native'
+   pod 'yoga', path: "#{rn_path}/ReactCommon/yoga/yoga.podspec"
+   pod 'React', path: rn_path

  pod 'react-native-safe-area', path: '../node_modules/react-native-safe-area'

end

+ post_install do |installer|
+   installer.pods_project.targets.each do |target|
+     if target.name == "React"

+     end
+   end
+ end

react-native link

Run command below:

react-native link react-native-safe-area

Usage

Work with views

Use withSafeArea to apply safe area insets to views automatically.

import { withSafeArea } from 'react-native-safe-area'

withSafeArea(component[, applyTo][, direction])

A higher-order component which applies safe area insets automatically to the wrapped component.

  • component : Component – Wrapped component.
  • applyTo : string – (Optional) Specify property to apply safe area insets.
    • margin – style.margin. (Default)
    • padding – style.padding.
    • absolutePosition – style.topstyle.bottomstyle.left and style.right.
    • contentInset – contentInset and contentOffset for scroll views.
  • direction : string – (Optional) Specify direction to apply safe area insets.
    • top – Apply to top.
    • bottom – Apply to bottom.
    • left – Apply to left.
    • right – Apply to right.
    • topAndLeft – top + left.
    • topAndRight – top + right.
    • bottomAndLeft – bottom + left.
    • bottomAndRight – bottom + right.
    • horizontal – left + right.
    • horizontalAndTop – horizontal + top.
    • horizontalAndBottom – horizontal + bottom.
    • vertical – top + bottom.
    • verticalAndLeft – vertical + left.
    • verticalAndRight – vertical + right.
    • all – horizontal + vertical. (Default)
Simple view example
const SafeAreaView = withSafeArea(View, 'margin', 'all')

class App extends Component<{}> {
  render() {
    return (
      <SafeAreaView>
        <View />
      </SafeAreaView>
    )
  }
}
ScrollView example
const SafeAreaScrollView = withSafeArea(ScrollView, 'contentInset', 'vertical')

class App extends Component<{}> {
  render() {
    return (
      <SafeAreaScrollView>
        <View />
      </SafeAreaScrollView>
    )
  }
}

You can also apply safe area insets to FlatList and SectionList.

Enhanced component’s APIs

get wrappedRef : ref

Returns wrapped component’s ref.

get currentSafeAreaInsets : SafeAreaInsets

Returns current safe area insets.


Handle safe area manually

import SafeArea from 'react-native-safe-area'

If you want to use SafeAreaInsets type, you can import it like below:

import SafeArea, { type SafeAreaInsets } from 'react-native-safe-area'

Retrieve safe area insets for root view

SafeArea.getSafeAreaInsetsForRootView()
  .then((result) => {
    console.log(result)
    // { safeAreaInsets: { top: 44, left: 0, bottom: 34, right: 0 } }
  })

Handle safe area insets changed event

class App extends Component<{}> {
  // To keep the context of 'this'
  onSafeAreaInsetsForRootViewChange = this.onSafeAreaInsetsForRootViewChange.bind(this)

  componentDidMount() {
    // Add event listener
    SafeArea.addEventListener('safeAreaInsetsForRootViewDidChange', this.onSafeAreaInsetsForRootViewChange)
  }

  componentWillUnmount() {
    // Remove event listener
    SafeArea.removeEventListener('safeAreaInsetsForRootViewDidChange', this.onSafeAreaInsetsForRootViewChange)
  }

  onSafeAreaInsetsForRootViewChange(result) {
    // Called every time that safe area insets changed
    console.log(result)
    // { safeAreaInsets: { top: 0, left: 44, bottom: 21, right: 44 } }
  }
}
