I am building an app about photos and
I want to create a photo sharing feature like Apple's Photos App.
Please see Steps to Reproduce and attached project.
The current share method has the following issues
The file name of the shared photo changes to “FullSizeRender”.
The creation and update dates of shared photos will change to the date they were edited or shared.
I want to ensure that the following conditions are definitely met
Share the latest edited version.
The creation date should be when the original photo was first created.
How can I improve the code?
