Shrinks content from view along both axes.

Slides content into view from the left.

None

13.

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

To create a smooth fade effect.

To make an animation faster.

To make an animation loop a specified number of times.

None

14.

What is the role of the 'targetState' in MutableTransitionState?

It adjusts the speed of the animation.

It sets the initial size of the animation.

It determines the end state of the animation.

It modifies the color of the animated component.

None

15.

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

To adjust the padding of a composable.

To create custom animations for any composable.

To perform animations on list scrolling behavior.

To animate the visibility of a composable when it appears or disappears.

None

16.

Which AnimatedVisibility function is used to shrink content from view behind a vertical clip bounds line?

shrinkVertically()

slideInHorizontally()

shrinkHorizontally()

shrinkOut()

None

17.

Which component allows you to change animation parameters like duration and easing?

VisibleState

LayoutModifier

AnimationSpec

Crossfade

None

18.

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 using the tween() function with a delayMillis parameter.

By setting the visible parameter to false.

None

19.

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

2.0

None

20.

What does the expandVertically() animation effect do?

Expands the content into view vertically.

None

21.

Which animation effect would you use to make content slide out of view to the left?

shrinkVertically

expandHorizontally

fadeOut

slideOutHorizontally

None

22.

How can you ensure that an animation starts automatically in Jetpack Compose?

Applying the default animation behavior.

Using the animateStart() function.

By using MutableTransitionState with targetState.

Setting the visible parameter to true.

None

23.

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

By using the fadeIn() function.

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

By adding a delay parameter to the animation.

By setting the visible parameter to true.

None

24.

Which function is used for animating the replacement of one composable with another?

tween()

animateContentSize()

Crossfade()

expandVertically()

None

25.

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

It specifies which composable should be visible.

It defines the background color of the fade.

It controls the size of the fade area.

It sets the duration of the fade.

None
