Summary
Convert the example app from a bare React Native app to a full Expo app using Expo Router with list → detail navigation.
Motivation: The single long scroll list was hard to navigate and slow for UI automation. With Expo Router, each demo is directly accessible by URL slug. Using
expo prebuildeliminates manual native dir maintenance and issues like the Hermes V1 symbol mismatch.Changes
Structure:
android/andios/dirs — now generated viaexpo prebuild(gitignored)Gemfile— native dirs managed by Expoexample/app/directory with file-based Expo Router routesexpo prebuildinstead ofbundle install/pod installNavigation:
app/index.tsx) — SectionList of all 19 demos grouped by category:app/[demo].tsx) — tap any demo for full-screen view with back buttonDemo components:

CI passes (lint, build-library, build-android, build-ios).
Videos will be added after merge + rebase of the per-property transitions PR.
