ViewportChangedEvent class

Occurs when the visible section of the Mini App is changed. eventHandler receives an object with the single field isStateStable. If isStateStable is true, the resizing of the Mini App is finished. If it is false, the resizing is ongoing (the user is expanding or collapsing the Mini App or an animated object is playing). The current value of the visible section’s height is available in this.viewportHeight.
