Introduction
ScreenShareStore provides a complete set of screen sharing APIs, including full-screen sharing on mobile, and screen / window source enumeration and targeted sharing on desktop (Win/Mac).
Notice:
Use ScreenShareStore.shared singleton to get the ScreenShareStore instance. Do not attempt to initialize directly.
Note:
Screen sharing state updates are delivered through the screenShareState publisher. Subscribe to it to receive real-time updates about screen sharing status.
Features
Screen Sharing: Start and stop screen sharing, with support for iOS App Group and desktop capture property configuration.
Source Enumeration: Enumerate shareable screens and application windows with thumbnails and icons for building source-picker UI (desktop only).
