Installing different versions of open jdk through Homebrew(assuming already installed) and already having Java 8.

We need to install a tool called jenv - Java version manager which is similar to nvm(nodeJs version manager).

brew install jenv

Export the jenv path to .bash_profile or .zshrc - whatever you are using. I am using .zshrc

Install with Homebrew:

$ brew install postgresql@14

(The version number 14 needs to be explicitly stated. The @ mark designates a version number is specified. If you need an older version of postgres, use postgresql@13, for example.)

Attempting mysql -u root fails with Access denied for user 'root'@'localhost immediately after doing brew install mariadb and starting mariadb with brew services start mariadb.

To fix it (with MariaDB still running):

1. sudo mysql then enter your Mac user password
2. ALTER USER 'root'@'localhost' IDENTIFIED BY 'newrootpassword'; replacing newrootpassword with the password you wish to use for the MariaDB root user.
3. Ctrl-C to exit mysql.

You should then be able to connect to MariaDB with mysql -u root -p, then entering the root password when prompted.

You should not use the Open SSH client that comes with Git for Windows. Instead, Windows 10 has its own implementation of Open SSH that is integrated with the system. To achieve this:

1. Start the ssh-agent from Windows Services:

• Type Services in the Start Menu or Win+R and then type services.msc to launch the Services window;
• Find the OpenSSH Authentication Agent in the list and double click on it;
• In the OpenSSH Authentication Agent Properties window that appears, choose Automatic from the Startup type: dropdown and click Start from Service status:. Make sure it now says Service status: Running.

2. Configure Git to use the Windows 10 implementation of OpenSSH by issuing the following command in Powershell:

git config --global core.sshCommand C:/Windows/System32/OpenSSH/ssh.exe

Widget

A widget is the basic type of controller in Flutter Material. There are two type of basic Widget we can extend our classes: StatefulWidget or StatelessWidget.

Stateful

StatefulWidget are all the widget that interally have a dynamic value that can change during usage. It can receive an input value in the constructor or reference to functions. You need to create two classes like:

import 'package:flutter/material.dart';
import 'dart:ui' as ui;
import 'package:flutter/services.dart' show rootBundle;
import 'dart:async';
import 'dart:typed_data';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
