How to use the react-sweet-state.createSubscriber function in react-sweet-state

export const ThemeContainer = createContainer(
  Store,
  {
    onInit: () => ({ getState, dispatch }) => {
      // this gets currently called also when component remounts
      // so it is important to check state status and apply default only on first mount
      const { color } = getState();
      if (!color) {
        dispatch(actions.change());
      }
    },
  }
);

        const title = `Todo ${n}-${i + 1}`;
        dispatch(actions.add(title));
      });
    },
