I don't understand why everything is not working after I did a 'flutter clean'. At nearly the same time I accidentally pressed the Debug button near the play button. Not sure which one messed things up though. Here is the message I get in the console:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:processDebugGoogleServices'.
> No matching client found for package name 'com.example.activities'
