React Native with Node.js后端中出错

我收到的错误：

应用程序屏幕上没有显示任何内容，但当我登录控制台时，它正在从终端中的服务器获取数据

应用程序屏幕feedscreen.js

import React, {useEffect, useState} from 'react';
import {ActivityIndicator, Text, View, FlatList} from 'react-native';
import stylesheet from '../src/styles/HomeStyle';
import AsyncStorage from '@react-native-community/async-storage';

const FeedScreen = props => {

  const [text, setText] = useState('loading');
  const Boiler = async () => {
    const token = await AsyncStorage.getItem('token');
    fetch('http://192.168.*.*:3000/post', {
      headers: new Headers({
        Authorization: 'Bearer ' + token,
      }),
    })
      .then(res => res.json())
      .then(data => {
        console.log(data);
        setText(data.text);
      });
  };
  useEffect(() => {
    Boiler();
  }, []);

  return (
    <View style={stylesheet.container}>
      <Text>{text}</Text>
    </View>
  );
};

export default FeedScreen;

setText（数据[0].text）
但这只能返回一个数据yyes，如果要显示所有数据，可以使用FlatList。如果
