I got an error like this:
Any one give suggestions that how to show the alert in Android and IOS in react-native

Answer 1

Are you sure you are including it from the correct path?
I get the same error when I imported Alert from react library and NOT react-native.
so the working thingie is:
import React, { Component } from 'react';
import { View, Alert } from 'react-native';
and the non-working one was:
import React, { Component, Alert } from 'react';
import { View } from 'react-native';

Answer 2

I think you forget to import Alert from react-native
import { Alert } from 'react-native';
and then you can show Alert like this
Alert.alert("Alert message");

Answer 3

We just need to import it correctly:
import { Alert } from 'react-native';
Then use it in your project as written in your code and it will work for both platforms :
Alert.alert('Alert', 'email is not valid, Please enter correct email', [{text: 'Ok'}]);
