[iOS] My app is listed in the share applications list but it doesn't work
Hey,
I have an issue with this package, and I've been going in circles for hours.
When I try to share a file, my app is listed in the list of apps that can receive files.
However, when I tap on it, there's a brief animation that makes me believe it's working, but nothing actually happens.
It seems like the file isn't being received by the app. Does anyone have any idea what could be causing this issue?
I've tried following the main page of the package and copying the example from Git.
Does any of you can help me please ?

Ok it works. I reverted back to an old save. Did everything again and it works.
@AlexandreRousseau36 i have this issue with vcard i believe the issue is with not having a handler in ShareViewController
I have the same issue, no error when I flutter build ios --release and run the app. But when I am trying to share an image or a PDF file, the screen flash quickly and nothing happened. Any suggestions? What is your old save?
@SoCaliOS hi! i have the same issue when the app is killed, i share the content and the splash screen flash and closed. Can you fix it?
