How to install Dart in Ubuntu?

Dart is a programming language designed for the development of mobile, desktop, web, and server applications. It is an object-oriented, garbage-collected language that has syntax similar to the C programming language.

Dart can be compiled to either native code or JavaScript. It is developed and maintained by Google.

In this article, I will discuss how to install the Dart programming language in Ubuntu.

Prerequisites

You should have access to a user account with sudo privileges.

Installing Dart in Ubuntu

You can follow the instructions that are given below to install the Dart programming language on a Ubuntu system.

Before installing Dart make sure the local package repository is updated –

sudo apt update
sudo apt upgrade -y

Next, use the following command to install HTTPS support for apt –

sudo apt install apt-transport-https 

Add Dart SDK repository

Import the GPG key by using –

sudo sh -c 'wget -qO- https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -'

Add the Dart SDK repository by usingĀ  –

sudo sh -c 'wget -qO- https://storage.googleapis.com/download.dartlang.org/linux/debian/dart_stable.list > /etc/apt/sources.list.d/dart_stable.list'

Installing Dart

Once the Dart SDK repository gets added to your system, use the given command to refresh the local package repository –

sudo apt update

Run the following command to install Dart on your system –

sudo apt install dart

Press y and then enter if it asks for your confirmation.

Setup environment variable
