Get the Dart SDK

The Dart SDK has the libraries and command-line tools that you need to develop Dart web, command-line, and server apps. If you’re developing only mobile apps, then you don’t need the Dart SDK; just install Flutter.

To learn about other tools you can use for Dart development, see the Dart tools page. To learn about what’s in the SDK, see Dart SDK overview.

Install the Dart SDK

As the following instructions show, you can use a package manager to easily install and update the Dart SDK. Alternatively, you can build the SDK from source or download the SDK as a zip file.

Choose one of these options:

Install using Chocolatey

To use Chocolatey to install a stable release of the Dart SDK, run this command:

C:\> choco install dart-sdk

To install a dev release, run this command:

C:\> choco install dart-sdk --pre

To upgrade the Dart SDK, run this command (add --pre to upgrade the dev release):

C:\> choco upgrade dart-sdk

Install using a setup wizard

Alternatively, use the community-supported Dart SDK installer for Windows. You can use the wizard to install stable or dev versions of the Dart SDK.

Windows Dart Setup Wizard

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

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.

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.

About release channels and version strings

The Dart SDK has two release channels:

  • stable channel: stable releases, updated no more frequently than every 6 weeks; currently [calculating].
  • dev channel: prereleases, usually updated 1/week; currently [calculating].

Stable channel releases of the Dart SDK have version strings like 1.24.3 and 2.1.0. They consist of dot-separated integers, with no hyphens or letters.

Dev channel releases of the Dart SDK (prereleases) have additional characters, starting with a hyphen (-). For example, Dart 2 prereleases have version numbers starting with 2.0.0-dev such as 2.0.0-dev.69.5.

You can get stable and dev channel releases using the instructions above, or you can download the SDK as a zip file.
