Expo Router Patterns

Stack Navigator Configuration

Root Layout Setup

Use screenOptions on the Stack component to set defaults for all screens. Do NOT explicitly list every screen - routes are auto-discovered from the file structure.

// app/_layout.tsx
import { Stack } from 'expo-router';

export default function RootLayout() {
  return (
    <Stack screenOptions={{ headerShown: false }} />
  );
}

Per-Screen Configuration
