What is the main purpose of using the MVI architectural pattern in application development?

The main goal of the architectural pattern MVI (Model-View-Intent) is to ensure predictable application state management and clear separation of responsibilities between components. In MVI:

• Model stores the application state.
• View displays the state and sends user intents.
• Intent represents user intentions or events that are transformed into state changes.

This approach simplifies debugging, testing, and maintenance, as the application state is always unambiguous and updated through an event stream.

Example:

// Intent: user pressed a button
sealed class UserIntent {
    object LoadData : UserIntent()
}

// Model: state
data class ViewState(val isLoading: Boolean, val data: List<String>?)

// View reacts to the state and sends Intent
