通过State重新渲染地图点位后，老的点位不会清除掉，并且点位会随着地图拖动而移动

"react": "16.0.0", "react-native": "0.50.4", "react-native-amap3d": "^0.8.0", 更新到最新版本后，通过state重新渲染地图上的点位，老的点位不会被清除掉。新加的点位会随着地图的移动而移动。 之前我提过类似的bug，之前解决了。但是现在又出现了。 这是链接 代码如下

` import React, {Component} from 'react' import {StyleSheet, Image, View} from 'react-native' import {MapView, Marker} from 'react-native-amap3d'

export default class MarkerExample extends Component { static navigationOptions = { title: '添加标记', }

state = { list: [1, 2, 3, 4, 5, 6], }

_renderImageMarker = () => <Image style={styles.customIcon} source={require('../../images/flag.png')}/>

_update = () => this.setState({list: [11, 12, 13, 14, 15, 16]})

render() { return {this.state.list.map(item => <Marker key={item} icon={this._renderImageMarker} title={'Marker' + item} coordinate={{ latitude: 39.906901 + (item * 0.01), longitude: 116.397972 + (item * 0.01), }} /> )} } }

const styles = StyleSheet.create({ customIcon: { width: 40, height: 40, }, })`
