iOS Emulator Crash on Sign-In Button Click in Flutter App


I am encountering a persistent issue while attempting to open my Flutter app on the iOS emulator. The problem arises when I click on the “Sign In with Google” or any other button in the app, causing an immediate crash. I have already executed flutter doctor, and no issues were reported.

To provide more context and aid in troubleshooting, I am willing to share additional code files if needed. Please let me know which files or sections of code would be most helpful for diagnosing and resolving this problem. I am seeking guidance on identifying the root cause of the crash and implementing a solution.

Any insights, suggestions, or recommendations would be greatly appreciated. Thank you!
