I have one question. how can i handle rember state on bottomnavigation switch. I have a home screen with a composable that has a

var isPlayingState by remember { mutableStateOf(false) }

and set it in clickable (Box)

isPlayingState = if (player.isPlaying) {
    player.pause()
    false
} else {
    player.play()
    true
}

If i navigate to the second tab and navigate back the value ist false and not the last state i set ?why?

it is likely that the declared variable is no longer in composition when you navigate to the other tab. one way to resolve this is to hoist the isPlayingState out of the scaffold of your content

Or, depending on how ViewModels are scoped, put the state into the viewModel
