# This command works like bash magic.sh
   You have to create "magic.ps1" file and put some commands in there like
  # flutter clean
  # flutter pub get
To run it "powershell -File <FileName>"
  
  both commads will run synchronously
  
  first "flutter clean" will run
  then "flutter pub get" will run

  the powershell in VScode 
  
  if you dont want to use powershell command you can use 
  bash command
