Dart and package root -


I'm playing some code using the DART VM from the command line. The command is: 

  DART - check-package-root = / dART / package_ test_service.dart   
 Although I get an error:  
  gf_service.dart ': Error: Line 7 Position 1: Library Handler Import' Package Begins: Start / Start 'as Startup;   
 I'm confused with the DIR referenced by "pocket-root" argument, of course, looking at the "Start / Start Data" file, so it exists. The package-root folder is also correct.  
 Is there anything I remember?  
 Thanks   
 
 
 Normally you  -package-root  argument is not required, but the directory containing the script file should have a symbolic link to the package directory of your package.  Pub find  should create these simulations
