Flutter Lost connection to device

Question

I use Iphone 11 emulator. I hit run button and got this:

Launching lib/main.dart on iPhone 11 in debug mode...
Running pod install...
Running Xcode build...
Xcode build done.                                           37.0s
Waiting for iPhone 11 to report its views...
Debug service listening on ws://127.0.0.1:65405/L1H3N-Q0JFU=/ws
Syncing files to device iPhone 11...
Lost connection to device.

It opens the app and shut down immediately. I performed flutter clean but it's not working. This is my flutter doctor":

When I tried to run the app from the XCode, it showed me the actual error. I was missing the google Ad Identifier inside the Info.plist file. Once I added it, it started working fine.

Thanks for your time and help.

Thank you. Your comment helped me to solve my problem. In my case I needed to add apiKey parameter in FirebaseOptions and only xCode show the error
