Install the Dart SDK on Windows

Step 1: Install Chocolatey

Open PowerShell as administrator. Check the execution policy:

Get-ExecutionPolicy

Allow scripts for this session only:

Set-ExecutionPolicy Bypass -Scope Process -Force

Run the install command from the Chocolatey website:

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

Check it:

choco -v

Step 2: Install the Dart SDK

choco install dart-sdk

Step 3: Set the environment variables

Chocolatey adds Dart to the PATH. If dart is not found after you open a new window, add the bin folder of the SDK (for example C:\tools\dart-sdk\bin) to the PATH under System Properties, Environment Variables.

Step 4: Check the installation

Open a new PowerShell window:

dart --version

A first program

void main() {
  print('Hello, Dart!');
}
