    Symmetic encryption

For symmetic encryption, you can use the following:
To encrypt:
openssl aes-256-cbc -salt -a -e -in plaintext.txt -out encrypted.txt

To decrypt:
	import 'package:flutter/material.dart';

	class OverlayWithHole extends StatelessWidget {
	@override
	Widget build(BuildContext context) {
	return Scaffold(
	appBar: AppBar(title: Text("Flutterclutter: Holes")),
	body: _getExperimentOne()
	);
	}
