tree_state_machine
tree_state_machine is a Dart package for defining and executing hierarchical state machines.
Features
- Hierarchical state trees
- Asynchronous message processing
- Stream based event notifications
- Declarative state definitions
- Nested state machines
Overview
The tree_state_machine package provides APIs for defining a hierarchical tree of states, and
creating state machines that can manage an instance of a state tree. The state machine can be used
to dispatch messages to the current state for processing, and receive notifications as state
transitions occur.
Refer to UML state machines for further conceptual background on hierarchical state machines.
