How to switch OpenSSL version on Mac using Homebrew?

Scenario: you have both OpenSSL 1.0 and 1.1 installed (using Brew) in your OSX system and you want to switch the current active version without removing other versions that already installed. Here is how to do it.

Step 1 - List all OpenSSL versions

$ ls -al /usr/local/Cellar/openssl*

/usr/local/Cellar/openssl:

import 'package:flutter/material.dart';
import 'package:shared_preferences/shared_preferences.dart';

//https://stackoverflow.com/a/53107519/10409567
void main() async {
  // load the shared preferences from disk before the app is started
  WidgetsFlutterBinding.ensureInitialized();
  final prefs = await SharedPreferences.getInstance();

  // create new theme controller, which will get the currently selected from shared preferences
