For a CRUD (Create, Read, Update, Delete) app using MVVM with Jetpack Compose, you would typically structure your app like this:

Architecture Breakdown

1. View (Jetpack Compose UI)

   • Displays data to the user.

   • Collects user inputs and forwards them to the ViewModel.

2. ViewModel

   • Holds UI state and exposes it via StateFlow or LiveData.

   • Calls repository methods to perform CRUD operations.

   • Uses MutableState in Compose for UI state management.

3. Repository

   • Acts as a single source of truth for data.

   • Fetches data from local database or remote API.

4. Model (Data Layer)

   • Represents the data structure.

   • Uses Room database for local persistence.

5. Database (Room)

   • Stores data locally.

   • Provides DAO (Data Access Object) for querying.
