isActive

Whether a zoom or pan gesture is currently being applied to the content, or the content has not yet settled back to its resting state after such a gesture ended.

Becomes true only when a touch gesture is actually consumed as a zoom or pan (not merely when a finger touches down), and remains true through any follow-up animation (e.g. the snap-back animation of Modifier.snapBackZoomable), then returns to false once the content is at rest.

This can be used to decide whether to show additional UI that should only be visible while the user is interacting with the content, such as an overlay that displays the zoomed content above a clipping parent.
