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.


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 upgrade -y

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

Add Dart SDK repository

Import the GPG key by using –

sudo sh -c 'wget -qO- | apt-key add -'

Add the Dart SDK repository by using  –

sudo sh -c 'wget -qO- > /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 –

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

Setup environment variable

After installing Google Dart SDK add its bin directory to the PATH environment variable –

export PATH="$PATH:/usr/lib/dart/bin"

To change it to all the future terminal sessions use –

echo 'export PATH="$PATH:/usr/lib/dart/bin"' >> ~/.profile

Check Dart version

You can verify the Dart installation by checking the version installed on your system.
