Screen

Screen components are used to configure various aspects of screens inside a navigator.

A Screen is returned from a createXNavigator function:

const Stack = createStackNavigator(); // Stack contains Screen & Navigator properties

After creating the navigator, it can be used as children of the Navigator component:

<Stack.Navigator>
  <Stack.Screen name="Home" component={HomeScreen} />
  <Stack.Screen name="Profile" component={ProfileScreen} />
</Stack.Navigator>

You need to provide at least a name and a component to render for each screen.

Props

name

The name to use for the screen. It accepts a string:

<Stack.Screen name="Profile" component={ProfileScreen} />

This name is used to navigate to the screen:

navigation.navigate('Profile');

It is also used for the name property in the route.

While it is supported, we recommend to avoid spaces or special characters in screen names and keep them simple.

options

Options to configure how the screen gets presented in the navigator. It accepts either an object or a function returning an object:

<Stack.Screen
  name="Profile"
  component={ProfileScreen}
  options={{
    title: 'Awesome app',
  }}
/>

When you pass a function, it'll receive the route and navigation:

<Stack.Screen
  name="Profile"
  component={ProfileScreen}
  options={({ route, navigation }) => ({
    title: route.params.userId,
  })}
/>

See Options for screens for more details and examples.

initialParams

Initial params to use for the screen. If a screen is used as initialRouteName, it'll contain the params from initialParams. If you navigate to a new screen, the params passed are shallow merged with the initial params.

<Stack.Screen
  name="Details"
  component={DetailsScreen}
  initialParams={{ itemId: 42 }}
/>

getId

Callback to return an unique ID to use for the screen. It receives an object with the route params:

<Stack.Screen
  name="Profile"
  component={ProfileScreen}
  getId={({ params }) => params.userId}
/>

By default, calling navigate('ScreenName', params) identifies the screen by its name, and navigates to the existing screen instead of adding a new one. If you specify getId and it doesn't return undefined, the screen is identified by both the screen name and the returned ID.

This is useful for preventing multiple instances of the same screen in the navigator, e.g. - when params.userId is used as an ID, subsequent navigation to the screen with the same userId will navigate to the existing screen instead of adding a new one to the stack. If the navigation was with a different userId, then it'll add a new screen.

component

The React Component to render for the screen:

<Stack.Screen name="Profile" component={ProfileScreen} />

getComponent

Callback to return the React Component to render for the screen:

<Stack.Screen
  name="Profile"
  getComponent={() => require('./ProfileScreen').default}
/>

You can use this approach instead of the component prop if you want the ProfileScreen module to be lazily evaluated when needed. This is especially useful when using ram bundles to improve initial load.

children

Render callback to return React Element to use for the screen:

<Stack.Screen name="Profile">
  {(props) => <ProfileScreen {...props} />}
</Stack.Screen>

You can use this approach instead of the component prop if you need to pass additional props. Though we recommend using React context for passing data instead.

Note: By default, React Navigation applies optimizations to screen components to prevent unnecessary renders. Using a render callback removes those optimizations. So if you use a render callback, you'll need to ensure that you use React.memo or React.PureComponent for your screen components to avoid performance issues.
