The invertible package is a Dart library designed to define and work with invertible functions—functions that can be reversed to retrieve the original input. It supports composing multiple invertible functions while preserving their invertibility, enabling safe and predictable transformations. Ideal for mathematical operations, data processing pipelines, and reversible computations, it ensures correctness through type safety and clear function contracts. The library is lightweight and compatible across all major platforms, making it suitable for cross-platform applications requiring bidirectional logic.
