reactjs - React-Pose 动画退出问题

Question

我正在使用react-pose使窗口内和窗口外的通知动画化。

“进入”过渡非常流畅，但是退出时 - 动画非常激进。

有人遇到过这个问题吗？我可以在任何地方上传视频屏幕截图来说明问题(除了 YouTube)。

这是我的代码:

import React, { Component } from 'react';
import PropTypes from 'prop-types';
import { connect } from 'react-redux';
import posed, { PoseGroup } from "react-pose";

import classNames from 'classnames';
import "./index.scss";

import key from 'keymaster';
import Notification from '../../components/Notification';

const NotificationPose = posed.div({
  enter: { 
    opacity: 1, 
    x: '0%',
    transition: { 
      duration: 300, 
      ease: 'easeIn' 
    } 
  },
  exit: { 
    opacity: 0, 
    x: '100%',
    transition: {
      duration: 500,
      ease: 'easeOut'
    }
  }
});

class NotificationCentre extends Component {

  static propTypes = {
    notifications: PropTypes.array,
  };
  static defaultProps = {
    notifications: []
  };

  constructor(props) {
    super(props);
    this.className=this.keyScope='NotificationCentre';
  }
  render(){
    return (
      <div className={`${this.className}`}>
          <PoseGroup>
          {
            this.props.notifications.map((d, i) => {
              return (
                <NotificationPose key={`notification-anim-${i}`}>
                  <Notification
                    key={`notification-${i}`}
                    active={false}
                    {...d}/>
                </NotificationPose>

              );
            })
          }
          </PoseGroup>
      </div>
    );
  }
}

const mapDispatchToProps = dispatch => ({});
const mapStateToProps = state => ({
  tvShowsList: state.tvShows.fetchingTVShowsListHasSucceeded,
});

export default connect(mapStateToProps, mapDispatchToProps)(NotificationCentre);

PosedGroup 要求每个子项都有唯一的关键属性来跟踪进入和退出子项。

如文档中所示 ( Here )

Every child must be provided a unique key property for PoseGroup to track entering and exiting children.

避免使用数组索引作为键，因为输入的新元素将与删除的元素具有相同的键。相反，使用唯一的 ID，例如 notification.id，它将正常工作。
