flutter를 실행해보려고 dart를 설치하는 문서/영상을 찾아보니

Powershell 에서 커맨드명령으로 실행하더군요

파워쉘을 윈도우즈 버전으로 먼저 설치합니다.

powershell.exe -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((

New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPRO FILE%chocolateybin"

그후에 파워쉘에서 

dart를 설치합니다.

Get-BinRoot is going to be deprecated in v1 and removed in v2. It has been replaced with Get-ToolsLocation (starting with v0.9.10), however many packages no longer require a special separate directory since package folders no longer have versions on them. Some do though and should continue to use Get-ToolsLocation.
