A fine-grained reactive programming library for Dart and Flutter applications with automatic dependency tracking.
Signals.dart is a reactive programming library for Dart and Flutter that implements a fine-grained reactivity system. It provides automatic dependency tracking and efficient state management through signals, allowing developers to build responsive applications with minimal boilerplate code.
Dart and Flutter developers building reactive applications who need efficient state management with automatic dependency tracking and surgical UI updates.
Developers choose Signals.dart for its fine-grained reactivity model that automatically tracks dependencies, lazy evaluation for performance optimization, and surgical rendering capabilities that minimize unnecessary widget rebuilds in Flutter applications.
Reactive programming made simple for Dart and Flutter
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Automatically tracks dependencies and frees them when not needed, based on Preact Signals, enabling efficient state updates without manual boilerplate.
Signals only compute values when read, optimizing performance by avoiding unnecessary calculations, as highlighted in the README.
Works across all Dart platforms including Flutter, Dart JS, Shelf Server, CLI, and VM, making it versatile for various project types.
Widgets rebuild only specific parts of the tree that need updating, reducing unnecessary renders in Flutter applications for better performance.
Compared to established libraries like Riverpod, signals.dart has fewer community resources, tutorials, and third-party integrations, requiring more DIY solutions.
Requires installing multiple packages (e.g., signals, signals_flutter) and configuring lints or hooks, which can add initial setup overhead compared to single-package solutions.
Adopting signals necessitates moving away from traditional Flutter state management patterns, which may involve a steeper learning curve for teams familiar with Provider or setState.
