DropWidget<D extends Drip<DState> , DState, SelectedState> class
A widget that listens to a Drip and rebuilds when the Drip emits a new state. That state is then passed to the builder function. To avoid unnecessary rebuilds, the builder function is only called when the selector function returns a new value. The selector function is called with the current state of the Drip and should return a value that is used to determine whether the builder function should be called.
