// In _layout file import { NativeTabs } from 'expo-router/unstable-native-tabs'; export default function Layout() { return ( <NativeTabs> <NativeTabs.Trigger name="home" /> <NativeTabs.Trigger name="settings" /> </NativeTabs> ); }
Example
// In a tab screen import { NativeTabs } from 'expo-router/unstable-native-tabs'; export default function HomeScreen() { return ( <View> <NativeTabs.Trigger> <Label>Home</Label> </NativeTabs.Trigger> <Text>This is home screen!</Text> </View> ); }
Note: You can use the alias
NativeTabs.Triggerfor this component.
