[Bug]: Save Image not working on iOS 12

[maxhis]

Platform

iOS 12.5.5

Plugin

share_plus

Version

3.x ~ 4.x

Flutter SDK

3.0.0

Steps to reproduce

1. Share an image with Share.shareFilesWithResult([file_path], mimeTypes: ['image/png'])
2. Select Save image item in opened ShareSheet.

No error throws, but the image has not been saved to Camera Roll. The issue only occurs in iPhone 6(running iOS 12.5.5), which works as expected on iOS 15 devices.

Code Sample

final result = await Share.shareFilesWithResult([file_path], mimeTypes: ['image/png']);
log('Share image: ${result.status}');

[log] Share image: ShareResultStatus.success
