Packages
This repository uses a Melos-managed monorepo layout:
| Package | Description | Version |
|---|---|---|
| flutter_compositions | Core reactive composition primitives for Flutter | |
| flutter_compositions_lints | Custom lint rules to enforce best practices |
Quick Example
Features
- Vue-inspired API – Familiar
ref,computed,watch, andwatchEffect - Fine-grained reactivity – Powered by
alien_signals - Composable logic – Extract and reuse stateful logic with custom composables
- Type-safe DI –
provide/injectwithInjectionKey - Built-in composables – Controllers, animations, async data, and more
- Zero boilerplate – Single
setup()function replaces multiple lifecycle methods - Lint rules – Custom lints enforce best practices
Development
This is a Melos monorepo. To get started:
# Install Melos flutter pub global activate melos # Bootstrap the workspace melos bootstrap # Run tests across all packages melos run test # Run analysis melos run analyze
Running the Example App
cd packages/flutter_compositions/example
flutter run
Contributing
Contributions are welcome! Please feel free to submit a Pull Request.
Acknowledgments
Flutter Compositions is built upon excellent work from the open source community:
- alien_signals – Provides the core reactivity system with fine-grained signal-based state management
- flutter_hooks – Inspired composable patterns and demonstrated the viability of composition APIs in Flutter
We are grateful to these projects and their maintainers for paving the way.
