Amplify Configure Not Working

Amplify Configure Method Not working
I've setup Amplify and created basic authentication with Facebook and Signup. In addition, I've setup some basline data models in the Amplify Admin UI, which in turn created the GraphQL api configuration. So the two services I have now are the auth and api.

I've been following this tutorial to setup authentication via amplify:
https://aws.amazon.com/getting-started/hands-on/build-flutter-app-amplify/module-two/

I ran the following steps:

1. Amplify Init: -Create a new username on my aws console and provided the Access Key ID and Secret Key
2. Amplify Pull: I did not run amplify configure because I already have an existing backend environment setup, so I just ran the amplify pull command for the existing staging environment. This created the amplify folder under lib and the amplifyconfiguration.dart.

When I run main.dart I receive the following:

To Reproduce

Hey @markpearl apologies for the delayed response to your issue here - were you able to resolve your issue in the end?

Within your AmplifyConfiguration file it looks like you have keys for API Plugin but in your initialization dart code, you only added the AuthCognito plugin. Could you try adding our API plugin as well and see if that fixes your issue?

Hey, Yes this can be closed ! Thanks, Mark
