Expo Native UI

Expo Native UI Guidelines

For routes, links, stacks, tabs, modals, sheets, and headers, use the expo-router skill. For any motion — entering/exiting, gestures, springs, keyboard-driven UI — use the expo-animation skill.

Before picking any UI component, check expo-ui first. @expo/ui provides native equivalents — BottomSheet, Button, Picker, Slider, Menu, Section, Switch, SegmentedControl, and more — rendered as real SwiftUI on iOS and Jetpack Compose on Android, available in Expo Go on SDK 56+ with no custom build. Load the expo-ui skill to find the right component before falling back to React Native built-ins or community libraries. This skill (expo-native-ui) covers the surrounding structure: Expo Router navigation, layout, styling, and visual effects.
