React Native - Alert

React Native - Alert

In this chapter, we will understand how to create custom Alert component.

Step 1: App.js

import React from 'react'
import AlertExample from './alert_example.js'

const App = () => {
   return (
      
   )
}
export default App

Step 2: alert_example.js

We will create a button for triggering the showAlert function.

import React from 'react'
import { Alert, Text, TouchableOpacity, StyleSheet } from 'react-native'

const AlertExample = () => {
   const showAlert = () =>{
      Alert.alert(
         'You need to...'
      )
   }
   return (
      
         Alert
      
   )
}
export default AlertExample

const styles = StyleSheet.create ({
   button: {
      backgroundColor: '#4ba37b',
      width: 100,
      borderRadius: 50,
      alignItems: 'center',
      marginTop: 100
   }
})
