fadeOut

shrinkVertically

slideOutHorizontally

expandHorizontally

None

18.

What is the function of the 'enter' parameter in the AnimatedVisibility composable?

Defines the animation duration for all animations.

19.

What is the purpose of the AnimatedVisibility composable in Jetpack Compose?

None

20.

How can multiple animation effects be combined in AnimatedVisibility?

Using the + operator.

Using the tween() function.

By calling the functions sequentially.

None

21.

How can you make an animation start with a delay?

By applying a delay modifier to the composable.

By using the fadeIn() function directly.

By setting the visible parameter to false.

None

22.

What is the purpose of the targetState parameter in the Crossfade composable?

It specifies which composable should be visible.

It sets the duration of the fade.
