Overview
A Dart library for programmatically creating, reading, and modifying source map files. It enables developers to work with source maps in build processes, debugging tools, and code transformation pipelines. The package supports standard source map formats and provides utilities to map minified code back to original source locations. Ideal for tooling that requires precise error tracking or debugging in compiled or transpiled code.
