copyMedia property
Whether media picked from the iOS photo library is copied into the app's temporary directory.
Set it to false to skip the copy, for example to avoid duplicating
large videos. Each picked item then only carries its photo library
identifier, DarwinPlatformFile.assetIdentifier, and a ph:/// URI, and
its content cannot be read through the returned file: open the original
asset by its identifier instead, which needs photo library access.
Only applies to FileType.image, FileType.video and FileType.media,
which use the photo library picker. It has no effect on macOS.
Implementation
final bool copyMedia;
