The following example is coding in typescript with Hooks.

import React, { useState, useEffect } from "react";

........

const App = () => {

   const [showScrollView, setShowScrollView] = useState(false);

   ......

   const onPress = () => {
    // toggle true or false
    setShowScrollView(!showScrollView);
  }

  ......

      
        {showScrollView ? () : null}
      
  ......

}
