Can this new API support in AnimatedVisibility also?. It can support suspend method in changing visibility. Check the issue ticket here

I don't see why it wouldn't support AnimatedVisibility also. It should just work.

Thinking currentState as val referring initialState is wrong. Technically it is wrong, it is not currentState.

Unable to do like this

val state = remember { SeekableTransitionState(false, true) }
    val transition = rememberTransition(state)
    val scope = rememberCoroutineScope()

    Column(
        Modifier.background(Color.White).fillMaxWidth(0.6f)
    ) {
        BasicText(transition.targetState.toString())
        BasicText(text = "Click", modifier = Modifier.clickable {
           scope.launch {
               if (state.currentState) state.animateToTargetState()
               else state.animateToCurrentState()
           }
        })
        Spacer(modifier = Modifier.padding(24.dp))
        transition.AnimatedVisibility(
            visible = { it }
        ) {
            BasicText("AnimatedVisibility")
        }
    }

This wont work

scope.launch {
               if (state.currentState) state.animateToTargetState()
               else state.animateToCurrentState()
           }

Because state.currentState is immutable , not mutableState. And there is overload composable functions of AnimatedVisibility one supports MutableTransitionState and another Transition.AnimatedVisiblity . To hold the currentState i have to create one more state and using LaunchedEffect to change that
