类型错误：组件不是添加forwardRef的函数

Question

您好，我试图将forwardRef添加到子组件，但在添加forwardRef时得到以下信息： TypeError: Component is not a function

该组件定义如下：

import React from 'react';
import { forwardRef } from 'react';
import { TextInputFocusEventData } from 'react-native';
import { NativeSyntheticEvent, StyleSheet } from 'react-native';
import { Input, InputProps } from 'react-native-elements';
import { Metrics, Colors } from '../../theme';
import Icons from '../Icons';


const CustomTextInput2 = forwardRef<TextInput, ICustomtextnputProps>((props, ref) => {
    const { name, required } = props;

    return (
        <Input
            rightIcon={<Icons name="right" />}
            placeholder={name?.concat(required ? '*' : '')}
            inputContainerStyle={styles.inputContainer}
            inputStyle={styles.inputText}
            {...props}
        />
    )
});
....

这是堆栈跟踪：

ExceptionsManager.js:180 TypeError: Component is not a function

我需要更改什么才能将forwardRef 添加到该组件吗？

通过 React.forwardRef 包装组件并从父组件传递 ref 后，您需要重新加载应用程序！我现在遇到了这个问题，看到了相同的错误消息，只需重新加载应用程序即可解决
