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

[Francesc]

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

[Francesc]

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)

[Francesc]

i.e., you want to remember what nav destination was selected and retain that on rotation

ohh thats interesting

[zt]

i kinda get it now
