"Could not build the application for the simulator." "Error launching application on iPhone 11."

I need some help, by accidentally think I deleted some flutter framework, and now I keep getting this error every time I want to launch my app on the IOS simulator through Android Studio.

I have updated the pods and I did change the pod.lock file but nothing seems to be working. Please could someone assist me?
