Answer 1

U need to delete the podfile.lock

then u need to run iOS folder from XCode to load assets for your projects

Go to ios folder and execute pod install and if it doesn't exist execute pod init then pod install

Please try Xcode -> Product -> Run

First delete podfile.lock and follow the steps below ;

flutter clean
flutter pub get
cd ios
pod install
flutter run

If doesnt work check your flutter channel and change it to beta.

flutter pub upgrade
flutter channel beta
flutter clean
cd ios
pod install
flutter run

Also you can switch back to stable typing below;

flutter channel beta

This solved my issue GitHub issue

try running these commands in your ios directory:

rm -rf Pods
rm -rf Podfile.lock
rm -rf ~/.pub-cache/hosted/pub.dartlang.org/
pod cache clean --all
flutter clean
flutter pub get
pod repo update
pod install
