@magicmass did you run flutter pub get for the example app? And also did you use the cli to initialize the categories it needs i.e. auth, storage, and analytics?

Hi @magicmass can you please share your pubspec.yaml file? When did you download the example app and have you made any modifications to the project?

I am seeing something similar.

  1. On Android, run the example app
  2. When the LandingPage is shown with the "Sign In" and "Sign Up" buttons, hit the back button until the Android home screen is displayed.
  3. Hit the Android app switcher button (rightmost) and return to the example app. App stays on the LoadingPage.
    Console log shows:

@kjones thanks for the additional context. I believe this is a separate error that needs additional investigation, please see issue: #99

@magicmass if you are getting the issue you mentioned when the app is first starting up and no interaction has occurred with the app, then the likely problem has to do with flutter. At this point, we recommend you to close your android emulator, run flutter clean, and restart the emulator.
