Get the Dart SDK

If you’re using Debian/Ubuntu on AMD64 (64-bit Intel), you can choose one of the following options, both of which can update the SDK automatically when new versions are released.

• Install using apt-get
• Install a Debian package

Install using apt-get

Perform the following one-time setup:

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

Then install the stable release of the Dart SDK:

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

Or, to install the dev release of the Dart SDK, run the one-time setup commands followed by:

$ sudo sh -c 'wget -qO- https://storage.googleapis.com/download.dartlang.org/linux/debian/dart_unstable.list > /etc/apt/sources.list.d/dart_unstable.list'
$ sudo apt-get update
$ sudo apt-get install dart

Install a Debian package

Alternatively, download Dart SDK as Debian package in the .deb package format.

• Stable channel
• Dev channel

Modify PATH for access to all Dart binaries

After installing the SDK, add its bin directory to your PATH. For example, use the following command to change PATH in your active terminal session:

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

To change the PATH for future terminal sessions, use a command like this:

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

Install Homebrew, and then run:

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

To install a dev channel release, use --devel:

$ brew install dart -- --devel

Upgrade

To upgrade when a new release of Dart is available run:

$ brew upgrade dart

To install a stable channel release when a dev release is currently active, run:

$ brew unlink dart
$ brew install dart

To upgrade to a dev channel release when a stable release is currently active, run:

$ brew upgrade --force dart -- --devel

Switch release

To switch between locally installed dart releases run brew switch dart <version>. Examples:

$ brew switch dart 1.24.3
$ brew switch dart 2.1.0

If you aren’t sure which versions of dart you have installed, then run:

$ brew info dart

The command output lists the latest stable and dev versions at the top, followed by your locally installed versions.
