None

13.

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

None

14.

When using AnimatedVisibility, how can you control the easing effect of an animation?

By using the fadeIn() function.

By setting the visible parameter to true.

By passing an easing value to the tween() function.

By adding a delay parameter to the animation.

None

15.

Which of the following is a predefined animation easing option in Jetpack Compose?
