I'm trying to run my Flutter application on iOS Simulator and I have found that video player throws the following exception on init:
[VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: PlatformException(VideoError, Failed to load video: The operation could not be completed, null, null)
After some googling, I found that there could be several fixes for that:
Upgrading flutter
Downgrading vide_player to 2.2.3
Configuring web server to support Range header
I am running the latest flutter version, also downgrading plugin didn't do pretty much anything. I made sure that web server does support Range header by playing video in a browser.
I have also checked network requests in flutter DevTools and it seems that network request is never made (looking at other API requests working fine).
Another note is that this problem does not happen on Android emulator/real device and video plays just fine.
What could cause this issue? Is there any possible way to enable more verbose logging to see what exactly causes the issue, or is there something I missing? Thanks for the help.

Flutter doctor comes back fine and I can run the Android emulator.
After hours of trouble shooting I can only think that there is some issue with my iOS folder.
I can go through the whole build process and then then app crashes on launch.
There is no error appearing in the terminal but I'm guessing there is a conflict somewhere.
Could it be the info.plist?
Has anyone got any ideas how I can troubleshot it.
Is there any where I can see a log file or an error?
I have tried emulator and physical device it won't launch past the splash on both
Thanks for any help
Flutter app doesn't show error logs when the app gets crashed in iPhones, it's common and irritating.
To solve it, by my experience, the protip is:
Open its ios folder in Xcode.
Select the device in which you want to run it.
Run it through Xcode, it will show the errors in Xcode's log panel which you can fix easily then.
I was recently trying to run my flutter app. However, when I tried to do so, I got the following error:
An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=3):

To try and fix this, I ran flutter doctor, where I got the following errors:

I have already tried uninstalling and reinstalling flutter, and I am still getting the same error. I am genuinely confused as to why this happening, and I would really appreciate some help. Thank you in advance!
After running this command: $ sudo softwareupdate --install-rosetta --agree-to-license,
the problem appears to have been fixed. I ran flutter doctor, and this was the output:

Install rosetta using.

UPDATED
To fix this, remove run rm -rf ~/flutter/bin/cache. Then run flutter run (you should run your app from terminal instead of IDE in order to Flutter download missing files). It's somehow works now.
Deleting the cache using rm -rf ~/flutter/bin/cache worked for me. This issue seems to have been caused by a bad Flutter installation. Running flutter pub get after deleting the cache should download the packages again and rebuild the project.
I'm new in flutter and iOS also, I was developing my first project in flutter using Windows then done but now I want to develop an iOS app. So, I copied my project from Windows and paste into Mac.
