None

12.

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

By adding a delay parameter to the animation.

By setting the visible parameter to true.

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

By using the fadeIn() function.

None

13.

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

Using the animateEnterExit() modifier.

Setting a different visible parameter for each child.

Applying different layout modifiers.

Using the duration parameter.

None

14.

How can multiple animation effects be combined in AnimatedVisibility?

Using the + operator.

With a custom animation spec.

By calling the functions sequentially.

Using the tween() function.

None

15.

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

Determines the content of the composable.

Defines the animation when the composable becomes visible.

Sets the starting position of the composable.

Defines the animation duration for all animations.

None

16.

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

It determines the end state of the animation.

It sets the initial size of the animation.

It modifies the color of the animated component.

It adjusts the speed of the animation.

None

17.

What happens when the enter and exit parameters are set to EnterTransition.None and ExitTransition.None in AnimatedVisibility?

No animations are applied when showing or hiding the content.

The content shrinks out of view.

The default fade animation is applied.

The content slides into view.

None

18.

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

Crossfade

LayoutModifier

VisibleState

AnimationSpec

None

19.

What does the expandIn() function do?

Shrinks content from view along both axes.

Reveals content using both horizontal and vertical clipping.

Fades content in without resizing it.

22.

What is the default behavior of AnimatedVisibility if no animation is specified?

It slides the content into view.

It instantly shows or hides the content.

It animates with a subtle fade.

It expands the content into view.

None

23.

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

To perform animations on list scrolling behavior.

None

24.

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

animateContentSize()

Crossfade()

tween()

expandVertically()

None

25.
