slideInHorizontally()

None

13.

What is the purpose of the repeatable() function in animation?

To create a smooth fade effect.

None

14.

Which function is used to make a composable fade into view?

expandIn()

slideIn()

scaleIn()

None

15.

What is the default alpha value for the fadeIn() function?

2.0

1.0

0.5

None

16.

What is the purpose of the animationSpec parameter in animation functions like fadeIn()?

To define the size of the content being animated.

To set the position of the animation.

To define the duration and easing of the animation.

To change the background color of the animation.

None

17.

What does the expandVertically() animation effect do?

Expands the content into view vertically.

Slides the content into view horizontally.

AnimationSpec

None

20.

How can different enter and exit animations be applied to individual children within an AnimatedVisibility scope?

Using the duration parameter.

Using the animateEnterExit() modifier.

Setting a different visible parameter for each child.

Applying different layout modifiers.

None

21.

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

It controls the size of the fade area.

It specifies which composable should be visible.
