Install Dart on your machine

on Saturday, 25th of July, 2020

In order to run Dart on your machine, you'll need to install the Dart SDK.

The following instructions install Dart 2. This book will be using Dart 2; Dart 1 will not work! If you already have the Dart SDK on your machine, ensure that it's version 2.0.0 or greater.

Installing the Dart SDK is straight forward if you use the command line. To check if you have Dart installed already, use the which dart command (on MacOS).

$ which dart

# should print 
=> /usr/local/bin/dart

Otherwise, install the SDK using the instructions for your machines operating system.

Mac OS

If you're using a Mac, it's likely that you have a program called Homebrew on your computer. If not, you need to install it. Homebrew is a command-line program that lets you download and manage software packages from the terminal.

We can install it easily from the command line. First, check to see if its installed:

$ brew -v

If your terminal prints Homebrew 1.x.x, then you're good to go. Otherwise, you need to install Homebrew. You can find instructions for installing Homebrew via the command line at https://brew.sh.

Homebrew will walk you through the steps in your terminal.

Second, install Dart SDK. Thanks to Homebrew, this is incredibly easy.

$ brew tap dart-lang/dart
$ brew install dart

Now, in your terminal, run this command to make sure everything is in its right place:

$ dart -v

=> Dart VM version: 2.x.x...

Windows

On Windows, the easiest way to install Dart is via the package manager, Chocolately. With Chocolatey on your machine, you simply have to run:

C:\> choco install dart-sdk

Linux

The easiest way to install on Ubuntu is with this series of steps. Using all these commands will ensure that Dart automatically updates whenever the newest version is released.

A one-time setup step:

$ sudo apt-get update
$ sudo apt-get install apt-transport-https
$ sudo sh -c 'curl https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -'
$ sudo sh -c 'curl https://storage.googleapis.com/download.dartlang.org/linux/debian/dart_stable.list > /etc/apt/sources.list.d/dart_stable.list'

Now, install the Dart SDK:

$ sudo apt-get update
$ sudo apt-get install dart
