BoxScrollView class Null safety

A ScrollView that uses a single child layout model.

ScrollViews are often decorated with Scrollbars and overscroll indicators, which are managed by the inherited ScrollBehavior. Placing a ScrollConfiguration above a ScrollView can modify these behaviors for that ScrollView, or can be managed app-wide by providing a ScrollBehavior to MaterialApp.scrollBehavior or CupertinoApp.scrollBehavior.
