This issue is raised by many, but their issue is solved by using one of the two methods shown here : Flutter iOS build failure error with Multiple commands after the Xcode upgrade
But, neither could solve my issue.
The error :
Launching lib/main.dart on iPhone Xʀ in debug mode...
Running pod install...
Running Xcode build...
Xcode build done. 5.2s
Failed to build iOS app
Error output from Xcode build:

This warning represents an extremely serious project misconfiguration and will likely cause some shell scripts in your project to be skipped entirely, leading to other build failures or missing files in the build directory. This will be a hard error in the future. (in target 'Runner')

After trying the first solution :
-> Changing to Legacy Build Mode and then cleaning the project in XCode as well as Android Studio using flutter clean
