我正在使用Expo和Firebase构建一个简单的跨平台应用程序。
我使用的是托管工作流，因为我不想接触原生代码。我还安装了react-native-firebase，因为这是我进入Firebase的"应用检查"功能的唯一途径。
我已经完全按照Expo和react-native-firebase的文档设置了我的应用程序，但是当我尝试向Firestore发出一个简单的请求时，我得到了以下错误：
Error: You have attempted to use a firebase module that's not installed on your Android project by calling firebase.app()
确保您拥有：
1.) imported the 'io.invertase.firebase.appReactNativeFirebaseAppPackage module in your MainApplication.java
2.)在RN "getPackages（）"方法列表中添加了新的ReactNativeFirebaseAppPackage（）行
在设置我的应用程序时，我安装了@react-native-firebase/app和@react-native-firebase/firestore，确保在app.json的插件中包含react-native-firebase，并将google-services.json和GoogleService-info.plist集成到项目的根目录中。
所以我不确定这里发生了什么。我错过了一个步骤吗？react-native-firebase在托管工作流中不工作吗？或者react-native-firebase与Firebase v9不兼容吗？我这样说是因为我使用的是名称空间方法来检索数据，而不是模块化：

useEffect(() => {
    const getDocs = async () => {
      const arr = []
      const snapshot = await firestore().collection("test-collection").get()
      snapshot.forEach((doc) => arr.push(doc.data()))
      setItem(snapshot)
    }
    getDocs()
  },[])

总之，以下是负责Firebase调用的整个组件：

• • 应用程序js**

import { useState,useEffect } from 'react'
import { StatusBar } from 'expo-status-bar';
import { StyleSheet, Text, View } from 'react-native';
import firestore from "@react-native-firebase/firestore"

export default function App() {

  const [item,setItem ] = useState([])

  useEffect(() => {
    const getDocs = async () => {
      const arr = []
      const snapshot = await firestore().collection("test-collection").get()
      snapshot.forEach((doc) => arr.push(doc.data()))
      setItem(snapshot)
    }
    getDocs()
  },[])

  console.log('item',item)

  return (
    <View style={styles.container}>
      <Text>Open up App.js to start working on your app!</Text>
      <StatusBar style="auto" />
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});
