tween()

None

12.

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 adding a delay parameter to the animation.

None

13.

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

CubicOutEasing

SpringOutEasing

BounceInEasing

LinearOutSlowInEasing

None

14.

Which parameter is mandatory when using the AnimatedVisibility composable?

exit

modifier

visible

enter

None

15.

What does the expandIn() function do?

Shrinks content from view along both axes.

Slides content into view from the left.

Fades content in without resizing it.

Reveals content using both horizontal and vertical clipping.

None

16.

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

It slides the content into view.

It expands the content into view.

It instantly shows or hides the content.

It animates with a subtle fade.

None

17.

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

To perform animations on list scrolling behavior.

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

To create custom animations for any composable.

To adjust the padding of a composable.

None

18.

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

Crossfade

VisibleState

AnimationSpec

LayoutModifier

None

19.

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

Determines the content of the composable.

Sets the starting position of the composable.

Defines the animation when the composable becomes visible.

Defines the animation duration for all animations.

None

20.

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

slideInHorizontally()

shrinkVertically()

shrinkHorizontally()

shrinkOut()

None

21.

What does the tween() function allow you to do?

Repeat animations indefinitely.

Set a specific position for animations.

Control animation duration and easing.

Modify the layout of a composable.

None

22.

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

Setting a different visible parameter for each child.

Using the animateEnterExit() modifier.

Using the duration parameter.

Applying different layout modifiers.

None

23.

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

Setting the visible parameter to true.

Using the animateStart() function.

Applying the default animation behavior.

By using MutableTransitionState with targetState.

None

24.

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 slides into view.

The default fade animation is applied.

The content shrinks out of view.

None

25.

What must be set to disable default animations in the parent AnimatedVisibility instance?

EnterTransition.None and ExitTransition.None

animationSpec to null

tween() duration to zero

scaleIn() with a value of zero

None
