Expo Sharing

Native module for Expo and React Native apps to trigger system-level share dialogs for files and URLs.

The expo-sharing library provides a standardized interface to invoke native share sheets on iOS and Android. It leverages UIActivityViewController and Intent.ACTION_SEND to pass data between applications without custom boilerplate. Developers use the shareAsync method to distribute local file URIs (images, PDFs, or logs) and web links to external targets like Slack or Mail. The API includes a isAvailableAsync check to verify device compatibility before execution. It handles the underlying system permissions and intent filters: ensuring a smooth handoff from the app to the OS.
