javascript - stop sequenced animation in React Native -

i have sequenced animation started button a, how can stop animation button b？thank you

store animation in state variable , call start or stop when click button:

constructor() {     super(props);      var my_animation = ... // define animation here      this.state = {         my_animation: my_animation;     } }  startanimation() {     this.state.my_animation.start(); }  stopanimation() {     this.state.my_animation.stop(); }  render() {     <button onpress={() => this.startanimation()} />     <button onpress={() => this.stopanimation()} /> } 

for more info on start , stop see https://facebook.github.io/react-native/docs/animations.html
