yafsm 2.0.0

Yet another Dart FSM.

2.0.0

• Machine, state, and transition labels are now optional, final parameters.
• It is now possible to select a starting state dynamically with start and pstart.
• The $ syntax for streams is gone. Instead, you pass callbacks to functions, e.g. onEnter, onChange.
• Machines no longer need to be disposed, as all callbacks are executed synchronously.
• Transitions may now receive callbacks when they are confirmed to have triggered via onTrigger.
• States may now have any number of nested machines.
• Nested machines are now completely separate. For the class-based style, they must be a different class. This allows them to be reused multiple times.
• Nested machines may now dynamically determine their initial state, including based on data in root state, if parameterized.
• Machine toString has been redesigned to account for potentially multiple nested machines.
• Instructed Claude Code to test extensively the entire new implementation. AI-generated tests are isolated in separate files.

1.1.1

• Improved tests.
• Improved class-based example with extends.
• Slightly modified toString implementation to not used parentheses in the nested case.
  • For example, on -> (blue -> (bright)) is now on -> blue -> bright.

1.1.0

• Allow configuration of queuing behavior for machines at construction time.
• Breaking Change. The new default is to not queue, and the clear parameter no longer exists.

1.0.4

• Added support for state and transition guards.

1.0.3

• It is no longer possible to use pstate without ptransition on accident.
• Parameterized states store their data while active, accessible with the data getter.

1.0.2

• Make machines and states listenable in the same way using streams.

1.0.1

• Improve semantics around transition execution.

1.0.0

• Initial version.
