下面是我的App.js代码:
import { StatusBar } from 'expo-status-bar';
import 'react-native-gesture-handler';
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import Home from './Root/Home'
import Profile from './Root/Profile'

我正在尝试用typescript实现这个,但它被证明是相当困难的。我也刚开始使用react native,所以我不知道我的ref是否正确,但这就是我目前所拥有的。
import * as React from 'react';
import { StyleSheet, Text, View, } from 'react-native';
import {Button} from 'react-native-elements';
import PhoneInput from 'react-native-phone-input';
我正在尝试在我的应用程序中实现React-Navigation。当我运行应用程序时,它崩溃了,并显示以下错误:
Element type is invalid: expected a string or class/function but got: object. You likely forgot to export your component from the file it's defined in.
我在这里搜索,但我尝试的任何解决方案都不起作用。这是我的代码:
索引:
import React, { Component } from 'react';

因此,我试图创建一个OTP身份验证流程。我在phoneInput屏幕上输入,然后移到OTP验证屏幕。在OTPvercification上,我的textInput无法工作。
App.js
import * as React from 'react'
import { Button, View, Text } from 'react-native'
import { NavigationContainer } from '@react-navigation/native'
import { createStackNavigator } from
我使用以下命令创建我的项目:
“创建-反应-本机应用程序AwesomeProject”
"cd AwesomeProject“
"npm启动“
当我在项目中使用"npm install --save react-navigation“命令进行react导航时,它会创建一个" react-navigation”文件夹,但当我启动项目“npm start”并运行ios模拟器时,它无法启动,并出现错误"Failed building JavaScript bundle".I want to go LogingForm.js to Status.js

在我的项目中,我遇到了上述错误,任何人都可以告诉我如何解决这个错误。
我面临的错误是:
useTheme错误:必须在NativeBaseConfigProvider中使用
此错误位于:
in Container
in ProductContainer (created by App)
in RCTView (created by View)
in View (created by App)
in App (created by ExpoRoot)
in ExpoRoot
in RCTView (created by View)
in View (created by AppContainer)
我在Expo中得到以下错误:“当使用对象作为参数调用导航时,您需要指定名称或键。” 我有一段调用LoginOptions的主要代码,包括: <LoginOptions title="Don't have a business account?" link="Create a free account" press="CreateAccount"/> 我试图将导航目的地作为“变量??-不确定正确的单词是什么”来传递。LoginOptions看起来像这样: import React from 'react';

嘿,我很难想出一个问题形式的正确流程。假设我有6个问题。我对它们的定义如下:
Dim firstStart As Boolean = True
Dim totalQs As Integer = 0
Dim currentQ As Integer = 0
Dim theAnswers() As String
Dim theQuestions() As String = {"Please scan barcode 1 then press NEXT", "" & _
"Plea
我对我的TextInput的关注点有问题。当我提交时,我想关注下一个TextInput。因为我的领航员,我对我的“这个”有问题。这是我的密码:
'use strict';
var React = require('react-native');
var styles = require('./common/styles.js');
var myStrings = require ('./common/strings-messages');
var name='';
var phone='';
