Overview
Alien Signals is a reactive state management library for Dart and Flutter that leverages the concept of signals to enable efficient, fine-grained reactivity. It allows developers to create reactive variables and computations that automatically update when dependencies change, reducing boilerplate and improving performance. Designed with simplicity and speed in mind, it integrates seamlessly into Flutter apps, offering a lightweight alternative to traditional state management solutions. The library emphasizes minimal overhead and predictable updates through signal-based dependency tracking.
