Is using a state machine mandatory in implementing the MVI architecture?

Using a state machine in the MVI (Model-View-Intent) architecture is not mandatory but highly recommended. The main idea of MVI is managing the application's state through well-defined states and transitions between them.

A state machine helps formalize these states and transitions, making the logic more predictable and easier to test. However, it is possible to implement MVI without an explicit state machine, simply by managing states through immutable objects and event handlers.

Thus, a state machine is a tool that simplifies the implementation of MVI but is not a strictly necessary component.
