None

13.

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.

None

14.

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

Modify the layout of a composable.

Repeat animations indefinitely.

Control animation duration and easing.

Set a specific position for animations.

None

15.

What does the expandIn() function do?

Slides content into view from the left.

Reveals content using both horizontal and vertical clipping.

Shrinks content from view along both axes.

Fades content in without resizing it.

None

16.

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

To delay the start of an animation.

To make an animation loop a specified number of times.

To make an animation faster.

To create a smooth fade effect.

None

17.

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

0.5

1.0

2.0

None

18.

Which parameter is mandatory when using the AnimatedVisibility composable?

visible

enter

exit

None

19.

What does the expandVertically() animation effect do?

Fades the content out of view.

Slides the content into view horizontally.

Shrinks the content vertically before disappearing.

Expands the content into view vertically.

None

20.

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

The default fade animation is applied.

The content slides into view.

The content shrinks out of view.

No animations are applied when showing or hiding the content.

None

21.

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

22.

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 animates with a subtle fade.

It instantly shows or hides the content.

None

23.

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

expandHorizontally

fadeOut

shrinkVertically

slideOutHorizontally

None

25.

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

Determines the content of the composable.
