我正在使用 react-native 构建一个随机应用程序。我正在尝试创建一个通过按钮激活的操作表,但我不断收到此错误。当我第一次运行该应用程序时它工作正常,但是当我再次重新加载该应用程序时,我每次都会收到此错误。我尝试使用我在网上找到的许多其他东西,但得到了相同的结果。请帮忙,我是 react-native 的新手 :(
import React from 'react';
import {Text, View, StyleSheet, TextInput, TouchableOpacity, Button} from 'react- native';

showActionSheet = () => {
this.ActionSheet.show()
}

TouchableOpacity.defaultProps = { activeOpacity: 0.8 };
const AppButton = ({ onPress, title }) => (
<TouchableOpacity onPress={onPress} style={styles.appContainer}>
<Text style={styles.appButtonText}>{title}</Text>
</TouchableOpacity>
);
const forgotpassword = () => {
