mycomponent.js

import * as React from 'react';
import {View, Text, Keyboard} from 'react-native';

const MyComponent = () => {
  const [showText, setShowText] = React.useState(true);

  // Use keyboard event (https://reactnative.dev/docs/keyboard)
  React.useEffect(() => {
    Keyboard.addListener('keyboardDidShow', _keyboardDidShow);
    Keyboard.addListener('keyboardDidHide', _keyboardDidHide);

    // cleanup function
    return () => {
      Keyboard.removeListener('keyboardDidShow', _keyboardDidShow);
      Keyboard.removeListener('keyboardDidHide', _keyboardDidHide);
    };
  }, []);

  const _keyboardDidShow = () => setShowText(false);
  const _keyboardDidHide = () => setShowText(true);

  if (showText) {
    return (
      <View>
        <Text>Bear, Beets, Battlestar Galactica</Text>
      </View>
    );
  }
  return null;
};

export {MyComponent};
