Describe the bug

Feature Request

Currently the generated Dart models lack the owner property when using appropriate auth rules despite this field existing in AppSync. This creates friction for Amplify-Flutter devs trying to make or filter requests including the owner field in a type safe manner.

Expected behavior

When I run amplify codegen models, I expect the generated Dart models to have a public owner field and associated query field definition. Such that I can access the following:

• Blog.owner
• Blog.OWNER.eq('user_name')

GraphQL schema(s)

type Post @model @auth(rules: [{allow: private, provider: iam,},
  { allow: owner, operations: [create, read, update, delete] }]){
  id: ID!
  title: String!
  content: String
  comments: [Comment] @hasMany
}

type Comment @model @auth(rules: [{allow: private, provider: iam},
  { allow: owner, operations: [create, read, update, delete] }]){
  id: ID!
  content: String
  post: Post @belongsTo(fields: ["postCommentsId"])
  postCommentsId: ID! 
}
