Unable to build app due to 'smart_auth' package – Flutter

I am trying to run a flutter app I am writing on my device but when I try to run, I never get past the "assembleDebug" stage and get this message in the terminal:

Launching libmain.dart on sdk gphone64 x86 64 in debug mode...

I had recently added the pinput package with smart_auth as one of its dependencies, causing the error. My flutter doctor had no issues. Flutter version is 3.7.7 and dart version is 2.19.4.
