이제 거의 끝났습니다! 삭제 아이콘을 TouchableOpacity 컴포넌트로 감싸고 onPress Props를 설정해주세요.

components/TodoItem.js

import React from 'react';
import {View, Text, StyleSheet, Image, TouchableOpacity} from 'react-native';
import Icon from 'react-native-vector-icons/MaterialIcons';

function TodoItem({id, text, done, onToggle, onRemove}) {
  return (
    <View style={styles.item}>
      <TouchableOpacity onPress={() => onToggle(id)}>
        <View style={[styles.circle, done && styles.filled]}>
          {done && (
            <Image
              source={require('../assets/icons/check_white/check_white.png')}
            />
          )}
        </View>
      </TouchableOpacity>
      <Text style={[styles.text, done && styles.lineThrough]}>{text}</Text>
      {done ? (
        <TouchableOpacity onPress={() => onRemove(id)}>
          <Icon name="delete" size={32} color="red" />
        </TouchableOpacity>
      ) : (
        <View style={styles.removePlaceholder} />
      )}
    </View>
  );
}
