Configuration and personalization

2. Import and use AlertContainer

Now, we need to import the AlertContainer component. Normally you would do this in your input file, such as App.js or App.tsx.

import {AlertContainer} from 'rn-custom-alert-prompt';

export const App = () => {
  return (
    <View>
      <AlertContainer />
      {/* Rest of your app code */}
    </View>
  );
};

Usage

Alert component

This is the typical system alert with the big difference that we can customize it and it returns a promise with the user's response.

Basic usage

import {Text, TouchableOpacity, View} from  'react-native';
import {Alert} from  'rn-custom-alert-prompt';

const  MyComponent  = () => {

 const handlePress = () => {
   Alert.alert('Title', 'Description')
 }

 return (
   <View>
	  <TouchableOpacity onPress={handlePress} >
        <Text>Open Alert</Text>
      </TouchableOpacity>

 )
