Overview
The args package provides a robust way to parse command-line arguments in Dart applications, supporting GNU and POSIX-style options. It enables developers to define structured parsers for flags, switches, and positional arguments, converting raw input into a clean, usable format. Ideal for CLI tools, scripts, and console applications, it simplifies argument handling with intuitive APIs and strong type safety. The package is lightweight, well-documented, and compatible across all major platforms including mobile, web, and desktop.
