  id: alert
  title: Alert

  Launches an alert dialog with the specified title and message.
  
  Optionally provide a list of buttons. Tapping any button will fire the respective onPress callback and dismiss the alert. By default, the only button will be an 'OK' button.
  
  This is an API that works both on Android and iOS and can show static alerts. To show an alert that prompts the user to enter some information, see `AlertIOS`; entering text in an alert is common on **iOS-only**

  ```js
  import React, { useState } from "react";
  import { View, StyleSheet, Button, Alert } from "react-native";
  
  export default function App() {
    const createTwoButtonAlert = () =>
      Alert.alert(
        "Alert Title",
        "My Alert Msg",
        [
          {
            text: "Cancel",
            onPress: () => console.log("Cancel Pressed"),
            style: "cancel"
          },
          { text: "OK", onPress: () => console.log("OK Pressed") }
        ],
        { cancelable: false }
      );
  
    const createThreeButtonAlert = () =>
      Alert.alert(
        "Alert Title",
        "My Alert Msg",
        [
          {
            text: "Ask me later",
            onPress: () => console.log("Ask me later pressed")
          },
          {
            text: "Cancel",
            onPress: () => console.log("Cancel Pressed"),
            style: "cancel"
          },
          { text: "OK", onPress: () => console.log("OK Pressed") }
        ],
        { cancelable: false }
      );
  
    return (
      <View style={styles.container}>
        <Button title="2-Button Alert" onPress={createTwoButtonAlert} />
  
        <Button title="3-Button Alert" onPress={createThreeButtonAlert} />
      </View>
    );
  }
  
  const styles = StyleSheet.create({
    container: {
      flex: 1,
      justifyContent: "space-around",
      alignItems: "center"
    }
  });
  ```
  
  ## iOS
  
  On iOS you can specify any number of buttons. Each button can optionally specify a style, which is one of 'default', 'cancel', or 'destructive'.
  
  ## Android
  
  On Android at most three buttons can be specified. Android has a concept of a neutral, negative and a positive button:
  
  - If you specify one button, it will be the 'positive' one (such as 'OK')
  - Two buttons mean 'negative', 'positive' (such as 'Cancel', 'OK')
  - Three buttons mean 'neutral', 'negative', 'positive' (such as 'Later', 'Cancel', 'OK')
  
  By default alerts on Android can be dismissed by tapping outside of the alert box. This event can be handled by providing an optional `options` parameter, with an `onDismiss` callback property `{ onDismiss: () => {} }`.
  
  Alternatively, the dismissing behavior can be disabled altogether by providing an optional options parameter with the cancelable property set to false i.e. `{ cancelable: false }`.
  
  Example usage:
  
  ```js
  // Works on both Android and iOS
  Alert.alert(
    'Alert Title',
    'My Alert Msg',
    [
      {
        text: 'Ask me later',
        onPress: () => console.log('Ask me later pressed')
      },
      {
        text: 'Cancel',
        onPress: () => console.log('Cancel Pressed'),
        style: 'cancel'
      },
      { text: 'OK', onPress: () => console.log('OK Pressed') }
    ],
    { cancelable: false }
  );
  ```
