Properties

expandProgress

public val expandProgress: Float

While in the middle of the animation, this represents the progress from 0f (collapsed) to 1f (expanded), or the other way around. If no animation is running, it's either 0f if the extra content is not showing, or 1f if the extra content is showing.

expanded

public var expanded: Boolean

Represents the current state of the component, true means it's showing the extra information. If its in the middle of an animation, the value of this field takes into account only the target of that animation.

Modifying this value triggers a change to show/hide the extra information.
