SelectRebuilder<S, E, A extends ReducerAction, T> class

Rebuild a portion of the widget tree when a selected portion of state changes.

The SelectRebuilder widget is designed be used in combination with ComponentWidget to scope rebuilding down to a specific section of the widget tree. This is because the ComponentWidget does not automatically rebuild on state change for performance reasons.

SelectRebuilder takes a store from the ComponentWidget and a select function that is responsible for taking in the stores state and returning the piece of that state which you want to trigger rebuild on. It also takes the bulider function in to build a widget based on changed value.
