Useful links: - https://airbnb.io/mavericks/#/new-2x Mavericks 2 is replacing MvRx, by removing usage of Rx by Flow, both internally and in the API. See the link ^ to have more intel, but basically, the changes are: session.rx() => session.flow() room.rx() => room.flow() subscribe { }.disposeOnClear() => onEach { }.launchIn(viewModelScope) Only using manually onEach requires to add launchIn,any other methods provided by Mavericks on viewModel and activity/fragment are already taking care of lifecycle.
