Defines a state tree that can be used in conjunction with a TreeStateMachine.
- Implemented types
Constructors
-
StateTree.new(InitialChild initialChild, {required List<
StateConfig> childStates, List<FinalStateConfig> finalStates = const [], String? logName}) -
Constructs a state tree that is is composed of the states in the list of
childStates, and starts in the state identified by theinitialChild.factory -
StateTree.root(StateKey rootKey, InitialChild initialChild, {TransitionHandler? onEnter, TransitionHandler? onExit, MessageHandler? onMessage, required List<
StateConfig> childStates, List<FinalStateConfig> finalStates = const [], List<TreeStateFilter> ? filters, String? logName}) -
Constructs a state tree with a root state identified by
rootKey.factory
