SequentialStrategy class

Queues actions and processes them one at a time, preserving order.

Unlike TakeLeading which ignores new actions, this strategy waits for the current action to complete before processing the next one.

Use this strategy when actions must be processed in order and none should be dropped, such as saving operations or sequential API calls.

Example:

b.onWithStrategy<SaveAction>(
  sequential(),
  (state, action) async* {
    await api.save(action.data);
    yield SavedAction();
  },
);
