I want to show an alert message immediately when I visit a specific page in my react native app. There should not be any Alert button, Alert should appear automatically whenever I visit the page. Thanks for your support.
import React, { useEffect, useState } from "react";
import {View, Text, StyleSheet, Alert} from 'react-native'
import { Ionicons } from '@expo/vector-icons';
const AlertTest = ({ navigation }) =>{
return (
<View style={{
backgroundColor: '#f1f1f1',justifyContent: 'center', alignItems: 'center',}}>
<Ionicons color="black" name="tv" size={100}/>
<Text>Hello World </Text>
</View>
);}
export default AlertTest;

import {View, Text, ToastAndroid} from "react-native";

const AlertTest = ({navigation}) => {
useEffect(() => {
alert("Some Alert");
// OR
ToastAndroid.show("Some Alert Toast", ToastAndroid.SHORT);
}, []);
return (
<View
style={{
backgroundColor: "#f1f1f1",
justifyContent: "center",
alignItems: "center",
}}>
<Ionicons color="black" name="tv" size={100} />
<Text>Hello World </Text>
</View>
);
};
export default AlertTest;

Please find the below code:
import React, { useEffect, useState } from "react";
import {View, Text, StyleSheet, Alert} from 'react-native'
import { Ionicons } from '@expo/vector-icons';
const AlertTest = ({ navigation }) =>{
useEffect(() => {
Alert.alert('Your alert msg here!')
},[])
return (
<View style={{
backgroundColor: '#f1f1f1',justifyContent: 'center', alignItems: 'center',}}>
<Ionicons color="black" name="tv" size={100}/>
<Text>Hello World </Text>
</View>
);}
export default AlertTest;
useEffect with [ ] will render one time only on-screen load.
Hope it will help you!
