Variables class

A utility class for managing and processing variables with support for environment variables, CLI arguments, and command execution.

This class handles variable substitution in strings using patterns like ${{VAR_NAME}} or ${VAR_NAME} and command execution using patterns like %{{COMMAND}} or %{COMMAND}.

Constructors

Variables(Map<String, dynamic> variables, ArgResults? globalResults)

Creates a new Variables instance with the specified variables and CLI results.

Variables.fromSystem(ArgResults? globalResults)

Creates a Variables instance using system environment variables
