null不是对象（评估RNtaptargetView.ShowSequence）

Question

我创建了项目expo，并安装了react-native-taptargetview，但是expo start我得到一个错误null不是一个对象（正在评估RNTapTargetView.ShowSequence）

import React, {useEffect,Component, useState, useCallback} from 'react';
import {View, Text, StyleSheet, Button,DeviceEventEmitter} from 'react-native';
import {
  AppTour,
  AppTourView,
  AppTourSequence,
} from 'react-native-taptargetview';
import TapTarget from './TapTarget';
export default class App extends Component{
  constructor(props) {
    super(props)

    this.appTourTargets = []
  }



  componentDidMount() {
    setTimeout(() => {
      let appTourSequence = new AppTourSequence()
      this.appTourTargets.forEach(appTourTarget => {
        appTourSequence.add(appTourTarget)
      })

      AppTour.ShowSequence(appTourSequence)
    }, 1000)
  }


  render() {
  return (
    <View style={styles.container}>
      <TapTarget
        SetAppTourTarget={appTourTarget => this.appTourTargets.push(appTourTarget)}
      />
    </View>
  );
}
}
const styles = StyleSheet.create({
  container: {
    flex: 1,
    width: '100%',
    marginTop:50,
  },
});

expo suport react-native-taptargetview？帮帮我
