I am also facing the same problem the file opens properly on the iPhone simulator iPhone 5S ios 10.3.1 but not able to open the file in iPhone 6 device having iOS 12.4.7 release build. Also shocking is the file opens on iOS simulator with iOS version 13.5. We have a release of the app soon and we are stuck with this issue. Can anyone please help.

Following is the output of my flutter doctor:

I've just run the example project on my iPhone 11 (iOS 13.6) on both debug and release mode, I can not reproduce your issue, I can open the downloaded files normally. It seems there is problem with your file type or mime type
