我的自定義組件上有一個函數，它基本上是一個回調，用于從調用它的地方重新呈現（this.setState（））組件。我正在為這些調用的正確語法而苦苦掙扎。你能幫忙嗎？自定義組件export class LanguageSelector extends Component {afterChange(callback: any){    callback();}導入 LanguageSelector 的其他組件：<LanguageSelector afterChange={() => { this.setState({}) }} ></LanguageSelector>語言選擇器    import React, { Component } from 'react';import {    View,} from 'react-native';import { TouchableOpacity } from 'react-native';import Flag from 'react-native-flags';import { Global } from '../global'import PropTypes from 'prop-types';export class LanguageSelector extends Component {    afterChange(callback: any) {        callback();    }    changeLang(lang: string) {        Global.localizedStrings.setLanguage(lang);        //this.setState({});    }    render() {        return (            <View style={{ paddingBottom: 10, flexDirection: "row", alignSelf: "flex-end" }}>                <TouchableOpacity onPress={() => this.changeLang('de')}>                    <Flag code="DE" size={32} />                </TouchableOpacity>                <TouchableOpacity onPress={() => this.changeLang('en-US')}>                    <Flag code="GB" size={32} />                </TouchableOpacity>            </View>        )    }}
