How to rewrite components into react 16 form

an expandable and shrinking react component. Inside the component, there is a button to switch between shrinking and expanding, and pull down, pull up and expand in the internal support of the component, and throw onChange events when changing

.

how to rewrite this component to the format recommended by React16.4

import React from "react";
import styles from "./style.scss";

class ExpandedView extends React.Component {

  constructor(props) {
    super(props);
    this.state = {
      expanded: false,
    };

    // 
    this.containerNode = null;
    this.startX = 0;
    this.startY = 0;
    this.endX = 0;
    this.endY = 0;

    this.clickArrow = this.clickArrow.bind(this);
    this.onContainerTouchStart = this.onContainerTouchStart.bind(this);
    this.onContainerTouchEnd = this.onContainerTouchEnd.bind(this);
  }

  componentWillReceiveProps(nextProps) {
    const { expanded: newExpanded, onChange } = nextProps;

    if (this.state.expanded !== newExpanded) {
      onChange && onChange(newExpanded);
      this.setState({ expanded: newExpanded });
    }

  }

  async componentDidMount() {
    let { expanded, onChange } = this.props;

    onChange && onChange(expanded);
    this.setState({ expanded });

    if (this.containerNode) {
      this.containerNode.addEventListener("touchstart", this.onContainerTouchStart);
      this.containerNode.addEventListener("touchend", this.onContainerTouchEnd);
    }
  }

  componentWillUnmount() {
    if (this.containerNode) {
      this.containerNode.removeEventListener("touchstart", this.onContainerTouchStart);
      this.containerNode.removeEventListener("touchend", this.onContainerTouchEnd);
    }
  }

  onContainerTouchStart(e) {
    this.startX = e.touches[0].pageX;
    this.startY = e.touches[0].pageY;
  }

  onContainerTouchEnd(e) {

    let { onChange } = this.props;

    this.endX = e.changedTouches[0].pageX;
    this.endY = e.changedTouches[0].pageY;
    const direction = getDirection(this.startX, this.startY, this.endX, this.endY, 30);

    // 
    if (direction === "up") {
      this.setState({ expanded: true });
      onChange && onChange(true);

      // 
    } else if (direction === "down") {
      this.setState({ expanded: false });
      onChange && onChange(false);
    }
  }

  // 
  clickArrow() {
    let { onChange } = this.props;

    this.setState((prevState) => {
      let expanded = !prevState.expanded;

      onChange && onChange(expanded);

      return { expanded };
    });
  }

  render() {
    const { expanded } = this.state;

    return (
      <div
        ref={node => this.containerNode = node}
        className={cn(styles.container, { [styles.collapsed]: !expanded })}
      >
        <div className={styles["arrow-wrapper"]} onClick={() => this.clickArrow()} />
        <div className={cn(styles["collapsed-panel"], { [styles.hide]: expanded })}>
          <div>collapsed</div>
        </div>
        <div className={cn(styles["expanded-panel"], { [styles.hide]: !expanded })}>
          <div>expanded</div>
        </div>
      </div>
    );
  }
}

export default ExpandedView;

I rewrote it as


  static getDerivedStateFromProps(nextProps, prevState) {
    const { expanded: currentExpanded, onChange } = nextProps;

    if (currentExpanded !== prevState.expanded) {
      onChange && onChange(currentExpanded);

      return {
        expanded: currentExpanded,
      };
    }

    return null;
  }
After

, I found that the setState of clickArrow will also call getDerivedStateFromProps, which makes it impossible to switch between shrink and expand. How should I solve this problem?
should the behavior of a component like this control its own state be performed within the component or just throw an event so that the external component decides the value of expanded by passing props
