问无法对已卸载的组件调用setState (或forceUpdate)。react-image-gallery上的内存泄漏

EN

class MyGallery extends Component {
    constructor(props) {
    super(props);
    this.state = {
      mediaSrc: [],
      isFullScreen: false
    };
  }

  componentWillMount() {
    const mediaSrc = this.props.myObject.pictures.map((picture) => {
      return { original: picture, thumbnail: picture };
    });
    this.setState({ mediaSrc });
  }

  _onImageClick(event) {
    if (this.state.isFullScreen) {
      this._imageGallery.exitFullScreen();
      this.setState({ isFullScreen: false });
    } else {
      this._imageGallery.fullScreen();
      this.setState({ isFullScreen: true });
    }
  }

  render() {
    return (
      <div className="dish row">
        <figure className="center col-12" >
          <div className="dish__preview_container">
            <ImageGallery
              ref={i => this._imageGallery = i}
              items={this.state.mediaSrc}
              onClick={this._onImageClick.bind(this)}
              showFullscreenButton={false}
              showIndex
              showPlayButton={false}
              showThumbnails={false}
            />
         </div>
      );
  }
}

MyGallery.propTypes = {
  myObject: PropTypes.object.isRequired,
}

Warning: Can't call setState (or forceUpdate) on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in the componentWillUnmount method.
