outerController property Null safety

ScrollController outerController

The ScrollController provided to the ScrollView in NestedScrollView.headerSliverBuilder.

This is equivalent to NestedScrollView.controller, if provided.

Manipulating the ScrollPosition of this controller pushes the inner body sliver(s) down. The position of the innerController will be set to ScrollPosition.minScrollExtent, unless you use ScrollPosition.setPixels. Visually, the inner body will be scrolled to its beginning.
