None

12.

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

shrinkVertically

fadeOut

None

13.

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

shrinkHorizontally()

shrinkOut()

slideInHorizontally()

shrinkVertically()

None

14.

How can you make an animation start with a delay?

By using the fadeIn() function directly.

By using the tween() function with a delayMillis parameter.

By applying a delay modifier to the composable.

By setting the visible parameter to false.

None

15.

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

It instantly shows or hides the content.

It expands the content into view.

It slides the content into view.

It animates with a subtle fade.

None

16.

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

AnimationSpec

Crossfade

VisibleState

LayoutModifier

None

17.

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

animateContentSize()

tween()

expandVertically()

Crossfade()

None

18.

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

By setting the visible parameter to true.

By adding a delay parameter to the animation.

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

By using the fadeIn() function.

None

19.

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

To make an animation loop a specified number of times.

To make an animation faster.

To create a smooth fade effect.

To delay the start of an animation.

None

20.

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 duration for all animations.

Defines the animation when the composable becomes visible.

None

21.

What does the expandIn() function do?

Reveals content using both horizontal and vertical clipping.

Shrinks content from view along both axes.

Fades content in without resizing it.

Slides content into view from the left.

None

22.

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

Applying different layout modifiers.

Setting a different visible parameter for each child.

Using the animateEnterExit() modifier.

Using the duration parameter.

None

23.

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

It determines the end state of the animation.

It modifies the color of the animated component.

It sets the initial size of the animation.

It adjusts the speed of the animation.

None

24.

Which parameter is mandatory when using the AnimatedVisibility composable?

modifier

visible

exit

enter

None

25.

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

It controls the size of the fade area.

It defines the background color of the fade.

It sets the duration of the fade.

It specifies which composable should be visible.

None
