Flutter Android internet doesnt work on real device, but works on emulator #55896
Description
Expected results: Application is working on real android device - Moto G5s Plus with internet connection - api calls
Actual results: Application works on real device but internet connection doesnt so I cannot even pass the login screen. But the error shows nothing about internet connectivity.

*I also added internet permissions to \android\app\src\debug\AndroidManifest.xml and
\android\app\src\profile\AndroidManifest.xml to test it, none of them works.
Tried also
flutter clean
flutter build apk
flutter install
And plain
flutter run -d ZY322HCR5P
