This is to avoid Windows Command Prompt window from changing the fonts and colors as it transitions into Powershell with its drawing progress bar. Instead simple console text will be printed: ``` C:\src\f\flutter>bin\flutter doctor Checking Dart SDK version... Downloading Dart SDK from Flutter engine 2c144c3eeb4b25fd78b90dd3e2a24c36f4201021... Expanding downloaded archive... Building flutter tool... ... ``` Fixes https://github.com/flutter/flutter/issues/74864
