1 year ago Hi @saculNiot thanks for opening this issue. Sorry for the confusion - first of all, I don't think amplify add codegen works with Amplify platform libraries, it's used with the AWS AppSync SDKs. Second, amplify codegen models command requires adding API category to your Amplify App (which creates the API folder in amplify/backend you saw in the error message).
For your use case - using existing AppSync resource with Amplify platform libraries, you should follow this documentation. With this, you can start communicating with your API by manually composing GraphQL document string.
I haven't been able to generate native models directly using the CLI. If you'd like to leverage the native model helper, you probably need extra manual steps. Here's what I tried as a workaround
- Get a copy of the model schema you composed when initially created the AppSync API, make sure the schema conform the specification of data modeling
- run
amplify add apifollowing the steps - Now you should be able to find this file
<your-project-root>/amplify/backend/api/<your-api-name>/schema.graphql - Empty the file and copy your existing API schema into this file and save
- run
amplify codegen models, you should get the native models underlib/modelsas well as theModelProvider
Please note if you run amplify push it will create a new AppSync API, so before you push, you many want to do amplify remove api.
I will dig around to see if there is a simple way to do this. Will update.

Description
I have an existing AppSync API that I need to use in a new flutter app. After initializing amplify in my project, i run the command "amplify add codegen --apiId xxxxxxxxxxxxxxxxx"
This results in a message saying "Successfully added API xxxx to your amplify project" but then says "Flutter Only supports the command $amplify codegen models."
When I run amplify codegen models, it says No Appsync API configured. Please add an API. When I run amplify status, it shows the API ,but with no provider plugin. If I update the backend-config.json in amplify/backend directory with the awscloudformation provider plugin, and run either amplify push or amplify codegen models it tells me there is no API folder in amplify/backend
Has anyone had success getting codegen to work for an existing appsync api with Flutter? I have tried everything.
