snapTo

Immediately sets the value to target without animation.

If an animation is running, it is cancelled. When notify is true (the default) a synchronous state update is triggered so readers re-render to reflect the new value immediately. Pass notify = false to set the value silently — e.g. to seed a start value right before retarget, where a re-render would schedule a relayout that races the first animation frame.

Must be called on the main thread.
