Overview
The posix package provides access to POSIX system APIs on macOS and Linux, enabling low-level system operations such as file manipulation, process control, and signal handling. It is designed for desktop applications requiring direct interaction with the underlying operating system. The package exposes native POSIX functions through a Dart interface, making it suitable for advanced system programming tasks. It supports macOS, Linux, Windows, Android, and iOS platforms, though full POSIX functionality is primarily available on macOS and Linux. This package is ideal for developers building tools that need fine-grained control over system resources.
