There's no constant named 'GET' in ModelOperation constants

[EricDunaway]

Description

The documentation describes the @auth directive as supporting the following operations

  create
  update
  delete
  read # Short-hand to allow "get", "list", "sync", "listen", and "search"

  get # Retrieves an individual item
  list # Retrieves a list of items
  sync # Enables ability to sync offline/online changes (including via DataStore)
  listen # Subscribes to real-time changes
  search # Enables ability to search using @searchable directive

Docs: Authorization rules

I get an error of Error: Member not found: 'GET'. when trying to build with models generated from a schema with a directive such as @auth(rules: [{allow: owner, operations: [get]}])

Looking at the source for the package the granular read operations are not available.
enum ModelOperation { CREATE, UPDATE, DELETE, READ } (src: packages/amplify_core/lib/src/types/models/auth_rule.dart)

Steps to Reproduce

1. Create a schema using @auth(rules: [{allow: owner, operations: [get]}]) or any of the granular read operations
2. Generate models amplify codegen models
3. Execute flutter run
4. See the build errors about the missing constants

Hi @EricDunaway Thanks for reporting this issue, I did some digging in Amplify platform libraries, that the ModelOperation definition is consistent as enum ModelOperation { CREATE, UPDATE, DELETE, READ }. It looks libraries don't support the finer control over the detailed read operations.

Do you have any specific use case requires the finer control where using read is insufficient?

[EricDunaway]

@HuiSF I am trying to prevent the use of list operations from FE clients

The auth rule works as intended when querying the API in the console, but the generated code is causing build failures due to the missing values.

I suppose this could be considered a bug with the model generator, but since the generated code matches what I defined in the schema, I feel the library is incorrect.

[HuiSF]

OK thanks for the detail. I couldn't think of a reason why the finer read operation control is not supported in the library, I need to do some digging and get back to you.
