找不到变量 atob
Screen1.js
import React,{useEffect} from 'react'
import {View,Text} from 'react-native'
import * as firebase from 'firebase/app';
import '@firebase/firestore';
const Screen1 = props =>{
useEffect(() =>
{
var dbh = firebase.firestore().collection("Jots").doc("note");
dbh.set({name:"pradeep"}) //The yellow warning is popped up in this line.
});
return(
<View>
<Text>Title</Text>
</View>
)
}
控制台

我只是按照博览会文档中的指南进行操作,但仍然不知道为什么会出现此问题.对此需要一个明确的解释.还有什么是 atob 变量?
I just followed the guide in the expo documentation but still don't know why this problem is occurring. Need a clear explanation on this. And also what is atob variable?
推荐答案
我尝试过降级,但这并不是我的解决方案.我不知道为什么.
I have tried downgrading but that's not resulted as a solution to me. I don't know why.
app.js中base64的全局导入解决了这个问题.
The global import of base64 in the app.js resolved this problem.
import {decode, encode} from 'base-64'
if (!global.btoa) { global.btoa = encode }
if (!global.atob) { global.atob = decode }
感谢您的回复.
