Can you try flutter clean or flutter pub cache repair and then flutter run to see if it helps ?

[fullflash]

yes we tried all clean workaround commands. like

cd ios
pod deintegrate
cd ..
flutter channel stable
flutter upgrade
flutter clean
flutter build ios

lutter clean 2>&1 >/dev/null
echo Updating Pod...
pod repo update

#--verbose

{if ! ( "${PWD##*/}" == 'ios') 2>&1 >/dev/null
    then cd ios
fi} 2>&1 >/dev/null

echo Removing pod files...
rm -rf Podfile.lock Pods/ 2>&1 >/dev/null

cd ..

echo Removing cached flutter dependency files...
rm -rf pubspec.lock .packages .flutter-plugins 2>&1 >/dev/null

echo Repairing pub cache... uzun cekir
flutter pub pub cache repair

echo Getting all flutter packages...
flutter packages get

cd ios

echo Running pod install...
pod install

upgraded with latest Xcode 12.5 still same error.

Thanks for these details. Can you provide flutter pub deps -- --style=compact ?
Maybe there could be some plugins that may not be compatible with nullsafety after you migrated and hence getting the linker error with the pods.

thanks for assistance
here are the pub deps logs
