StateGraph<Event, State> class
State graph.
Defined by States and Events. Makes transitions based on graph and (optionally) globalEvents.
Constructors
-
StateGraph(Map<
Type, Map< graph, {Map<Type, StateTransitionEntry< >State, Event> >Type, StateTransitionEntry< globalEvents = const {}})State, Event> > - State graph.
Properties
-
globalEvents
→ Map<
Type, StateTransitionEntry< State, Event> > -
Optional map of global events which can be called in any
State.final -
graph
→ Map<
Type, Map< Type, StateTransitionEntry< >State, Event> > -

Methods
-
call(
State state, Event event) → State -
Makes transition from
stateoneventbased on graph. -
callSideEffect(
State state, Event event) → void -
Calls side effect defined in graph for
stateandevent. -
findTransitionEntry(
State state, Event event) → StateTransitionEntry< State, Event> ? -
Finds graph's StateTransitionEntry for
stateandevent. If there's no such entry, globalEvents lookup is made. If no entry is found,nullis returned. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

toString(
) → String -
