Overview
A Flutter/Dart library for implementing finite state machines, enabling developers to define and manage legal state transitions with ease. It provides clear event-driven state changes and supports listening to state entry, exit, and transition events. Ideal for modeling complex workflows where state consistency and predictable behavior are critical. The package is platform-agnostic, supporting all major Flutter platforms. It promotes clean, maintainable code by decoupling state logic from UI components.
Use cases
- Managing multi-step user flows
- Modeling application lifecycle states
- Handling asynchronous workflows
- Implementing form validation state machines
- Enforcing business rule compliance
Key features
- Event-driven state transitions
- Callbacks for state entry/exit/transitions
- Type-safe state definitions
- Support for nested and hierarchical states
- Extensible and testable design
Suitable for
- Developers building complex stateful apps
- Teams needing deterministic state management
- Projects requiring auditability of state changes
- Applications with strict workflow rules
Considerations
- Steeper learning curve for beginners
- Requires careful planning of state graph
- May introduce overhead in simple state scenarios
- Limited built-in UI integration
