File.preview()
cannot animate from the thumbnail the user tapped. Apps need a separate native module for this transition.
Add an optional
sourceView
: Quick Look zooms from and back to it on iOS; Android scales the viewer app up from its bounds. Missing views keep the default animation. I have a patch for
expo-file-system
58.0.13. Would you accept this API?
await file.preview({ sourceView: thumbnailRef.current });
Draft PR.
