Overview
A Dart library designed to simplify configuration management by sourcing values from configuration files, command-line arguments, and environment variables. It enables developers to build flexible CLI tools that adapt to different environments without hardcoding settings. The package supports multiple platforms including Android, iOS, macOS, Windows, and Linux, making it ideal for cross-platform command-line applications. By prioritizing configuration sources in a defined order, it ensures predictable behavior and easy overrides during development, testing, and deployment.
