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.

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 😄. 
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
