Recipes

End-to-end solutions to real problems. Each recipe is a copy-pasteable file you can drop into a React Native app. Cross-links point to the API reference for deeper details.

UX flows

• Limited photo access + upgrade — iOS 14+ partial photo access, detect with isLimited, upgrade with requestFullAccess() and renderLimited.
• Onboarding permission wall — sequential multi-permission flow with stable id keys and resume() for settings round-trips.
• Voice note composer — inline microphone access using skipPrePrompt: "android".
• Speech recognition — iOS needs both MICROPHONE and SPEECH_RECOGNITION; Android needs only RECORD_AUDIO. Platform-aware sequential flow.
• Imperative camera access — button-triggered camera permission inside a mid-form flow (KYC, profile photo, ID capture) without unmounting form state.
• Location accuracy UI — render precise-vs-approximate map and ETA from result.metadata.locationAccuracy on iOS 14+ (Expo engine).

Platform-specific bundles

• Background location — foreground → background location using Permissions.BUNDLES.LOCATION_BACKGROUND.
• Bluetooth device pairing — BLE pairing using Permissions.BUNDLES.BLUETOOTH.

Reliability and testing

• Recheck on foreground — auto-detect permission changes made in system Settings outside your blocked-prompt flow (recheckOnForeground: true).
• Stale permission state — work around Expo's cold-start stale undetermined bug (expo/expo#42084).
• Android status normalization — when and why to enable normalizeAndroid and normalizePhotoLibrary.
• Testing with createTestingEngine — unit-testing components and hooks that use this library.
