Flutter app for iOS crash on startup with Firebase

Question

I have done research for for so long and have not yet found a solution for my issue. I am building an app for iOS using flutter and I moved the app from my windows machine to a virtual macOS. Now when I try to rum the app on the Iphone simulator (Iphone 11 pro Max), the app crashes on startup with this error:

Launching lib/main.dart on iPhone 11 Pro Max in debug mode...

Does anyone know what might be causing this error? I have added the GoogleService-Info.plist ursinne the add file in Xcode so now I don't know what's wrong. I hope anyone can help me and ill be so grateful!

Solution

I created a new project and now it works.
