Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

XCode is installed (via the App Store)
XCode command line tools are installed (xcode-select --install will prompt up a dialog)
Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

Flutter

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.

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
