How to customize AWS Amplify Flutter endpoints to use LocalStack

[Crackz]

Environment

• Amplify Flutter Version: 2.2.0
• Amplify Auth Cognito Version: 2.2.0
• Flutter Version: 3.24.0
• Dart Version: 3.5.0
• Platform: Flutter Mobile App

Current Implementation

I'm currently using AWS Amplify in my Flutter application with the following plugins:

• AmplifyAuthCognito for authentication

My initialization code looks like this:

Future<void> configureAmplify() async {
  try {
    final auth = AmplifyAuthCognito();
    await Amplify.addPlugins([auth]);
    await Amplify.configure(amplifyconfig);
  } on AmplifyAlreadyConfiguredException {
    logger.d('Amplify was already configured.');
  } catch (e) {
    logger.d('An error occurred configuring Amplify: $e');
  }
}

Question
For local development and testing, I want to redirect all AWS API calls from Amplify to LocalStack instead of the actual AWS services.

Is there a way to configure Amplify Flutter to use custom endpoints for auth specifically ?

I'm looking for a way to modify the amplifyconfig or use some other configuration method to point to my LocalStack instance running at http://localhost:4566 instead of the actual AWS Cognito endpoints.

Extra
it's supported by the js client

Amplify.configure({
  Auth: {
    Cognito: {
      // Lcoalstack configurations
      userPoolId: "eu-west-1_localUserPoolId",
      userPoolClientId: "userPoolClientId",
      userPoolEndpoint: "http://localhost:4566/eu-west-1_localUserPoolId", <- notice
      loginWith: {
        email: true,
      },
      signUpVerificationMethod: "code",
      userAttributes: {
        email: { required: true },
      },
    },
  },
});
