Advantages of MVI

  • Unidirectional and Cyclic data flow — It’s a design pattern where state flows down and event flows up. With such an approach, we can decouple composable that display a state in the ui from the parts of your app that store and change the state.
  • Single Source of Truth — The primary entity in this architecture, from which all other benefits emanate.
  • Easiness of Debugging — Since we have only one source of data, it’s easy to debug.
  • Easiness of Testing — In most cases, you just need to check a new state after. some event to validate the code, and it’s quite easy to do with the right implementation.
