Have you given respected permission on both Android and iOS ? — Ravindra Kushwaha, Apr 27 '20 at 05:06
For android it is working fine, I am not sure about iOS permission for reading directory/file.@Ra — Md Shahnawaz, Apr 27 '20 at 05:32
You need to make the permission entry in iOS like we do in the Manifest in Andorid case — Ravindra Kushwaha, Apr 27 '20 at 05:33

Seems like it there was an issue with the Flutter file_picker. Updating it should be a good fix.

Since iOS 13 you need to request access to files outside your app sandbox, via startAccessingSecurityScopedResource if not, you will see that length or open issue even though you do have a valid file path.

You can find more info in here which actually applies to files too.
