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.
My flutter app is crashing when I connect it to firebase and try to use it. It is only happening for this app(other apps are connecting fine). I am not sure why? Any suggestions would be greatly appreciated.I followed several tutorials and all of them did the same.
I have registered the app :
Provided bundle identifier
Attached the info-plist file

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.

For some reason, iOS Simulator stopped working. I can open iOS Simulator, but Android Studio not recognizes it. I've already tried to run via terminal, but it says not supported devices connected.
When I run flutter doctor it returns:

Since I'm on a Macbook 2011, I won't be able to upgrade Xcode. Is it possible to downgrade Flutter and Xcode to an older stable version? Would this solve the problem?
Thanks
If Android Studio does not recognize ios simulator even though you can separately open simulator on your Mac, you have to add command line tool on Xcode.
open Xcode then go to Xcode > preferences > select Locations tab. Then select Xcode version from the drop-down menu.
Open ios simulator again. Then Android Studio will recognize your device.
Flutter failed to start-up on real IOS device (not emulator), its working fine on the IOS emulator but when I connect my device its installed but fails to launch without printing any message on flutter application log.

There was an issue on Flutter repository as mentioned by #amer rawashdeh.
iOS 13.4 is now available, please update your iOS device and Xcode to v11.4 to keep your project newly working.
If you are on Flutter stable channel you need also to apply this guide to keep you project working with v11.4 Xcode
It seems the problem with ISO version 13.3.1 only
