This project aims to expose native navigation container components to React Native. It is not designed to be used as a standalone library but rather as a dependency of a full-featured navigation library.
Installation
iOS
Installation on iOS should be completely handled with auto-linking, if you have ensured pods are installed after adding this module, no other actions should be necessary
Android
On Android the View state is not persisted consistently across Activity restarts, which can lead to crashes in those cases. It is recommended to override the native Android method called on Activity restarts in your main Activity, to avoid these crashes.
For most people using an app built from the react-native template, that means editing MainActivity.java, likely located in android/app/src/main/java/<your package name>/MainActivity.java
You should add this code, which specifically discards any Activity state persisted during the Activity restart process, to avoid inconsistencies that lead to crashes.
import android.os.Bundle;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(null);
}
For people that must handle cases like this, there is a more detailed discussion of the difficulties in a series of related comments.
How can I take advantage of that?
Screens are already integrated with the React Native's most popular navigation library react-navigation and Expo. Read usage guide depending on if you are using Expo or not.
Supported react-native version
| version | react-native version |
|---|---|
| 3.0.0+ | 0.62.0+ |
| 2.0.0+ | 0.60.0+ |
Usage with react-navigation
Screens support is built into react-navigation starting from version 2.14.0 for all the different navigator types (stack, tab, drawer, etc). We plan on adding it to other navigators shortly.
To configure react-navigation to use screens instead of plain RN Views for rendering screen views, simply add this library as a dependency to your project:
# bare React Native project
yarn add react-native-screens
# if you use Expo managed workflow
expo install react-native-screens
Just make sure that the version of react-navigation you are using is 2.14.0 or higher.
You are all set 🎉 – when screens are enabled in your application code react-navigation will automatically use them instead of relying on plain React Native Views.
Disabling react-native-screens
If, for whatever reason, you'd like to disable native screens support and use plain React Native Views add the following code in your entry file (e.g. App.js):
import { enableScreens } from 'react-native-screens';
enableScreens(false);
Using createNativeStackNavigator with React Navigation
To take advantage of the native stack navigator primitive for React Navigation that leverages UINavigationController on iOS and Fragment on Android, please refer:
- for React Navigation >= v5 to the README in react-native-screens/native-stack
- for older versions to the README in react-native-screens/createNativeStackNavigator
Interop with react-native-navigation
React-native-navigation library already uses native containers for rendering navigation scenes so wrapping these scenes with <ScreenContainer> or <Screen> component does not provide any benefits. Yet if you would like to build a component that uses screens primitives under the hood (for example a view pager component) it is safe to use <ScreenContainer> and <Screen> components for that as these work out of the box when rendered on react-native-navigation scenes.
Interop with other libraries
This library should work out of the box with all existing react-native libraries. If you experience problems with interoperability please report an issue.
Guide for navigation library authors
If you are building a navigation library you may want to use react-native-screens to have control over which parts of the React component tree are attached to the native view hierarchy.
To do that, react-native-screens provides you with the components documented here.
