我试图调用FlatList的onEndReached上的函数，但它不起作用。
我在最后调用了this.state.pageNo，但它没有更新。我想在无限滚动中使用这个逻辑，但现在不能让它工作。

import React, { Component } from "react";
 import {
  View,
  Text,
  StyleSheet,
  Button,
  TouchableOpacity,
  FlatList,
  Alert
  } from "react-native";

 class InfiniteScrollRedux extends Component {
   constructor(props) {
      super(props);
      this.state = {
        loading: false,
        pageNo: 1,
        data: [
            { id: 1, name: "Name01" },
            { id: 2, name: "Name02" },
            { id: 3, name: "Name03" },
            { id: 4, name: "Name04" },
            { id: 5, name: "Name05" },
            { id: 6, name: "Name06" }
        ]
    };
}

myFunction = () => {
    this.setState({ pageNo: this.state.pageNo++ });
};

render() {
    return (
        <View>
            <FlatList
                data={this.state.data}
                renderItem={({ item }) => (
                    <View style={mystyle.mainCard}>
                        <Text style={mystyle.titleText}> {item.id} </Text>
                        <View style={{ marginTop: 200 }} />
                        <Text style={mystyle.nameText}> {item.name} </Text>
                    </View>
                )}
                keyExtractor={item => item.id}
                onEndReached={this.myFunction}
                onEndThreshold={0}
            />
            <Text style={{ margin: 20, padding: 20, fontSize: 20 }}>
                {this.state.pageNo}
            </Text>
        </View>
      );
   }
}

const mystyle = StyleSheet.create({
 mainCard: {
    backgroundColor: "#2F4F4F",
    marginBottom: 1,
    padding: 5
},
titleText: {
    fontSize: 20,
    color: "#F0FFFF"
},
nameText: {
    fontSize: 14,
    color: "#F0FFFF"
 }
 });

 export default InfiniteScrollRedux;
