how to divide entities and share it in clean architecture - flutter

Question

For my new project in flutter, I am trying to follow the Clean Architecture and diving each different feature in domain, data and presentation`.
Now, I have initiated with the Authentication feature where I have started creating the Entities however, I am pretty much confused and stuck on how to modularize the code based on the Clean Architecture practice.
For example,
The response of my login service is as follow,
so do I need to create entities and models for all JSON nested objects like for response , data , user , accountData and permissions ?
or is there any way to use IResponse to store common elements like status , message and data and then use only for relevant feature.
Not sure whether it is allowed to share entities in between the features. Like user block below can be a feature in Authorization and Employee
{
"status": "success",
"message": "successfully login",
"data": {
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6NywiaXNMb2dnZWRJbiI6dHJ1ZSwidGVuYW50SWQiOjEyLCJpYXQiOjE2MjU5OTE5MTAsImV4cCI6MTYyNjA3ODMxMH0.I0z9OIDnQS-MI1ya6usqycoryZ1TBwj3K52BRfrpMuY",
"user": {
"user_id": 7,
"email": "jd#gmail.com",
"first_name": "John",
"last_name": "Doe",
"phone": "",
"date_of_birth": "2015-08-06T00:00:00.000Z",
},
"accountData": {
"name": "Amazon",
"account_id": 1
},
"permissions": [
"ViewAllEmployee",
"AddNewEmployee"
]
}
}
