PS C:\> dart --version
Dart SDK version: 3.2.4 (stable) (Thu Dec 21 19:13:53 2023 +0000) on "win_x64"

If your development machine doesn't return a Dart version, add the SDK location to your PATH:

  1. In the Windows search box, type env.
  2. Click Edit the system environment variables.
  3. Click Environment Variables....
  4. In the user variable section, select Path and click Edit....
