### AccessibilityInfo Example

Source: https://reactnative-archive-august-2023.netlify.app/docs/accessibilityinfo

This example demonstrates how to check if reduce motion is enabled and if a screen reader is active. It also sets up listeners to update the UI when these states change.

```javascript
import React, {useState, useEffect} from 'react';
import {AccessibilityInfo, View, Text, StyleSheet} from 'react-native';

const App = () => {
  const [reduceMotionEnabled, setReduceMotionEnabled] = useState(false);
  const [screenReaderEnabled, setScreenReaderEnabled] = useState(false);

  useEffect(() => {
    const reduceMotionChangedSubscription = AccessibilityInfo.addEventListener(
      'reduceMotionChanged',
      isReduceMotionEnabled => {
        setReduceMotionEnabled(isReduceMotionEnabled);
      },
    );
    const screenReaderChangedSubscription = AccessibilityInfo.addEventListener(
      'screenReaderChanged',
      isScreenReaderEnabled => {
        setScreenReaderEnabled(isScreenReaderEnabled);
      },
    );

    AccessibilityInfo.isReduceMotionEnabled().then(isReduceMotionEnabled => {
      setReduceMotionEnabled(isReduceMotionEnabled);
    });
    AccessibilityInfo.isScreenReaderEnabled().then(isScreenReaderEnabled => {
      setScreenReaderEnabled(isScreenReaderEnabled);
    });

    return () => {
      reduceMotionChangedSubscription.remove();
      screenReaderChangedSubscription.remove();
    };
  }, []);

  return (
    <View style={styles.container}>
      <Text style={styles.status}>
        The reduce motion is {reduceMotionEnabled ? 'enabled' : 'disabled'}.
      </Text>
      <Text style={styles.status}>
        The screen reader is {screenReaderEnabled ? 'enabled' : 'disabled'}.
      </Text>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
  status: {
    margin: 30,
  },
});

export default App;
```
