Alternative installation methods

Download SDK archives

Download platform-specific SDK archives from the Dart SDK archive.

Available for all channels:

• Stable: Production-ready releases
• Beta: Preview of upcoming stable releases
• Dev: Latest development builds

After downloading, extract the archive and add the bin directory to your PATH.

Build from source

For advanced users, you can build the Dart SDK from source.

1. Install dependencies

   Linux:

   sudo apt-get install git python3 curl xz-utils
   

   macOS:

   • Install Xcode from the App Store

   Windows:

   • Install Visual Studio 2017 or newer with “Desktop development with C++”
   • Install Windows 10 SDK
2. Install depot_tools

   git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
   export PATH="$PATH:$PWD/depot_tools"
   
3. Get the source

   mkdir dart-sdk
   cd dart-sdk
   fetch dart
   
4. Build the SDK

   cd sdk
   ./tools/build.py --mode release create_sdk
   

Building from source is typically only needed for SDK contributors or for testing unreleased features.
