• Can someone please explain to me the advantages and necessity of mvi ?

`MVI` is different form the `MVVM` not by having UI events streamed to the `ViewModel`. Not only that to pre precise. Difference is how state is represented. In `MVVM` you generally have multiple streams for different pieces of data. `MVI` combines all that into single state class so you only have one state and whole UI is in sync where with `MVVM` UI can get out of sync because of multiple streams.
Thats the defining characteristics of `MVI` and you can add user events too but that’s optional.

Thanks for your explanation.
umm then mvi is better than mvvm .
Is this any framework for mvi ?

yes -&gt; <https://github.com/airbnb/mavericks>
but you can create your own, it’s simple-ish

OH Is this android mvi framework ?
Is this better than jetpack?

Question :
Actually  I ve heard about this framework from you firstly .
Now I dont understand well about this mavericks framework .
Honestly,I am a mobile developer but I used developed using java.
From this year, I am developing kotlin / jetpack .
Isn't kotlin/jetpack modern android development?
Should I learn about mvi architecture or mavericks ?

Jetpack doesn’t have `MVI`… anything. jetpack offers `ViewModel` and `Mavericks` is built on top of Jetpack `ViewModel` so it’s actually Jetpack :smile:. `MVI` was preferred before `Compose` and now with `Compose` it’s definitely better

MVI or MVVM I think it is depends on your business. Both of them are good and are worst

Talk about architecture it is not depends on Language, MVI can apply for every single language you like: Swift, Java, Kotlin, React Native
