Hi @mattRiddoch

Could you try removing the storage dependency you have in your pubspec.yaml?

It is possible the configure call is failing since you do not have any storage config in your amplifyconfiguration.dart.
That is also where your code differs from the docs setup steps.

Please run a flutter clean and then flutter run after as well.

Yeah removing the storage dependency did the trick! I will take the liberty of closing this out.
