How to maintain the final state when ScrollTrigger doesn't match the media

Go to solution Solved by GreenSock,

Recommended Posts

Context: I want the counting animation to happen only when the screen size is larger than 1024px 
So for example, starting number is 30 and the number will increment until the target number 50. 


However, when I resize the screen the number becomes 30 rather than staying at the target number 50. 


From the documentation, it seems like the ScrollTrigger will kill the animation and revert to its original state when the media query doesn't match

However, is there any way to maintain the final state? 

I'm using React and here is the code snippet

I'm new to this forum and GSAP  and thank you in advance for your help and guidance.

Here is the code 


import React, { useEffect } from "react"
import { gsap } from "gsap"
import { ScrollTrigger } from "gsap/ScrollTrigger"

const TestPage = () => {
  const stats = [{ finalNum: 50, startNum: 30 }]
  useEffect(() => {
      "(min-width: 1024px)": function () {
          trigger: "#counter-trigger",
          start: "-=350",
          end: "+=200",
          markers: true,
          animation: gsap.from(".mycounter", {
            duration: 0.55,
            innerText: stats[0].startNum,
            snap: {
              innerText: 1,
            once: true,
  }, [])

  return (
          height: "1000px",
          backgroundColor: "lightcoral",
        some stuff here
      <div my={100} id="counter-trigger">
        <span className="mycounter" style={{ fontSize: "80px" }}>

export default TestPage

You can return a cleanup function from your matchMedia function that'll get called when it doesn't match anymore, so just set it to whatever you want in there: 

  "(min-width: 1024px)": function () {
    return () => {
      document.querySelector("#mycounter").innerText = "50";

Does that help?
