I have an error when I tried to launch my project on my iPhone, the basic Flutter example is working on my iPhone but when I use my project I have this error.
I faced the same issue and none of the above work. Finally I resolved it by:
ios/.symlinks/plugins
contains extra plugin which you are not using.podfile.lock
in ios folder, if it exists.podfile
from ios folder.pods
folder in ios directory.flutter clean
in the terminal.flutter pub get
in the terminal.flutter run
in the terminal.
