ExitTransition

@Immutable sealed class ExitTransition

ExitTransition defines how an AnimatedVisibility Composable disappears on screen as it becomes not visible. The 3 categories of ExitTransition available are:

1. fade: fadeOut
2. slide: slideOut, slideOutHorizontally, slideOutVertically
3. shrink: shrinkOut, shrinkHorizontally, shrinkVertically

They can be combined using plus operator, for example:

import androidx.compose.animation.AnimatedVisibility
import androidx.compose.animation.core.spring
import androidx.compose.animation.core.tween
import androidx.compose.animation.fadeIn
import androidx.compose.animation.fadeOut
import androidx.compose.animation.slideInHorizontally
import androidx.compose.animation.slideOutHorizontally
import androidx.compose.foundation.layout.Stack
import androidx.compose.foundation.layout.fillMaxWidth
import androidx.compose.foundation.layout.height
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember

var visible by remember { mutableStateOf(true) }
AnimatedVisibility(
    visible = visible,
    enter = slideInHorizontally(
        // Offsets the content by 1/3 of its width to the left, and slide towards right
        initialOffsetX = { fullWidth -> -fullWidth / 3 },
        // Overwrites the default animation with tween for this slide animation.
        animSpec = tween(durationMillis = 200)
    ) + fadeIn(
        // Overwrites the default animation with tween
        animSpec = tween(durationMillis = 200)
    ),
    exit = slideOutHorizontally(
        // Overwrites the ending position of the slide-out to 200 (pixels) to the right
        targetOffsetX = { 200 },
        animSpec = spring(stiffness = Spring.StiffnessHigh)
    ) + fadeOut()
) {
    // Content that needs to appear/disappear goes here:
    Stack(Modifier.fillMaxWidth().height(200.dp)) {}
}
