Would movableContentOf be useful in cases like this?

IconButton(onClick = onClickFullscreen) {
    if (isFullscreen) {
        Icon(
            imageVector = Icons.Default.FullscreenExit,
            contentDescription = stringResource(R.string.close_fullscreen)
        )
    } else {
        Icon(
            imageVector = Icons.Default.Fullscreen,
            contentDescription = stringResource(R.string.open_fullscreen)
        )
    }
}

Nope, it's useful when you move something that's the same in more than 1 place

oh I see, thank you

I believe that whether it's the same or not is not the accurate answer, you can have the same composable in 2 places and you simply call the composable function in one place or the other and that's fine. What matters is if your composable is stateful, by having distinct composables in the

if

and

else

they have separate states and the state is lost when switching from the

if

to the

else

or vice versa (though you can save it with

rememberSaveable

). But the main difference is that, with

moveableContentOf

you can have the 2 composables be the same and have the same state when moving from one location to another.

ive seen it mainly used for landscape / portrait

if it's stateless, you don't gain anything from

moveableContentOf

though

i thought i might be able to use it in my app somewhere, but doesnt seem like theres anywhere suitable for it

this applies, for instance, to the navigation controller when you switch from portrait to landscape and want to have the same state with tabs (portrait) or rail (landscape)

ohh thats interesting
