* import { animationFrameScheduler } from 'rxjs'; * * const div = document.querySelector('div'); * * animationFrameScheduler.schedule(function(height) { * div.style.height = height + "px"; * * this.schedule(height + 1); // `this` references currently executing Action, * // which we reschedule with new state * }, 0, 0); * * // You will see a div element growing in height * ``` * * @static true * @name animationFrame * @owner Scheduler */ export declare const animationFrame: AnimationFrameScheduler;
