React Native 上几个有趣的问题

Question

我想分享我的 React Native 项目。在这里，我遇到了一些问题。我曾多次尝试解决，但都失败了。谁能解决这个问题？

我已经检查了所有关于堆栈溢出的问题。我可以保证这是一个真正的新问题。

错误类型：react-native； 试过：3 - 5 次；

import React, {useState, useReducer,useEffect} from "react"
import {View, Text, StyleSheet, Image, Dimensions, TouchableOpacity} from "react-native"



import * as Location from "expo-location"

const screenWidth = Dimensions.get("screen").width

export const LandingScreen = () => {

  const[errorMsg, setErrorMsg] = useState("")
  const [address, setAddress] = useState<Location.Address>()
  const [displayAddress, setDisplayAddress] = useState("Waiting for current location")
  
  useEffect(() =>{

      (async () =>{
          let { status } = await Location.requestPermissionsAsync()

          if(status !== "granted"){
           setErrorMsg(
              "permissions not granted ,Allow the app to use location service"
              
            )
          }

          let location: any = await Location.getCurrentPositionAsync()

        const {coords} = location

        if(coords){
          const{latitude, longitude} = coords;
          let addressResponse: any = await Location.reverseGeocodeAsync({
            latitude,
            longitude
          });

          for(let item of addressResponse){
            setAddress(item)
            let currentAddress = `${item.name}, ${item.street}, ${item.postalCode}, ${item.city}`
            setDisplayAddress(currentAddress)

            /*if(address.length > 0){
              setTimeout(()=>{
                navigate("HomeScreen")
              },1000)
