Meteorflux:meteorflux with react

Hi. I am using the meteorflux:meteorflux package. But all the examples are for blaze.

I am trying to figure out how to have a react component subscribe to a state change

for example:

State.modify('State.User.userSignedIn', function(state = false) {
      email: ,
      password: Action.password
    }, (err) => {
      if (err) throw err;

      return true;

I am not sure how I subscribe to the state change in my react component.
The documentation says
4.- Views automatically render themselves again when State changes.
Is this true for react components too?
