HeroControllerScopeModifier class

An inherited widget to host a hero controller.

The hosted hero controller will be picked up by the navigator in the child subtree. Once a navigator picks up this controller, the navigator will bar any navigator below its subtree from receiving this controller.

The hero controller inside the HeroControllerScope can only subscribe to one navigator at a time. An assertion will be thrown if the hero controller subscribes to more than one navigators. This can happen when there are multiple navigators under the same HeroControllerScope in parallel.
