Took a quick look through the sources (I'm aware they're not officially intended for local builds) but haven't found anything interesting (yet). First impressions:

- The API keys are obtained using flutter_dotenv, and omitted from the Git source but trivially extractable from the Play Store APK (using a rooted phone).

- After installing the .env file and building t4t locally, I was unable to log into the Android app using a Gmail account; every attempt left the app in a not-logged-in state. The same thing happened after replacing my local app with the Play Store version? (EDIT: After restarting the app I was able to proceed?)

- (nitpick/observation) When I tap a post, the app opens the user's post history, and I try scrolling the list, the view lags behind my finger. Can't tell if it's latency, dropped frames, or both together.

These are all public keys so I am not too worried, but I appreciate the heads up. I will make more effort to obfuscate them.
