We tested this and the amplify pull --sandboxId <...> works now.

@fjnoyp is testing this a bit more end to end.

@kaustavghosh06 can we get this merged tomorrow?

The codegen models look good. ModelProvider.dart is not compiling because it's missing an implementation of "getModelTypeByModelName". Once that is resolved this should be good to go.

Updated to include copying an empty amplifyconfiguration.dart file when initializing the flutter project. Wasn't sure what should be in the empty file so it has {} for now. Let me know what should be in there or update amplifyconfiguration.empty.dart in the PR with the expected contents

The codegen models look good. ModelProvider.dart is not compiling because it's missing an implementation of "getModelTypeByModelName". Once that is resolved this should be good to go.

To get the latest version of modelgen package for testing/debugging using yarn setup-dev, please update the dependency of amplify-codegen package on @aws-amplify/appsync-modelgen-plugin to the latest stable version example, currently it should be "@aws-amplify/appsync-modelgen-plugin": "^1.22.6",. Running yarn setup-dev then would update the lock file and use the latest modelgen. Note: Installing amplify CLI through npm or a self contained binary always fetches the latest version of dependencies and hence does not have this issue.
