Hello, I’m doing an application in reactnative and I’m trying to set a state but it doesn’t work, can you help me? follows the source(Obs the handleClickFooter function which does not arrow the state)

import React, { Component } from 'react';
import {
  StyleSheet, Text, View, Image, Button, Platform,
  TouchableOpacity,
  FlatList, Alert
} from "react-native"
import { androidClientId } from "./superSecretKey"

export default class App extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
      tela: "home"
    }
  }

  render() {
    return (
      <View style={styles.container}>
          <LoggedInPage name={this.state.login.name} photoUrl={this.state.login.photoUrl} />
      </View>
    )
  }
}

handleClickFooter = (param) => {
  try {
    this.setState({ tela: param }, () => {
      Alert.alert(this.state.tela)
    })
